Where to Buy Pediatric Blood Collection Tubes in the U.S.: Manufacturers and Distributors

Summary

• U.S. buyers can purchase pediatric blood collection tubes from manufacturers such as BD, Greiner Bio-One, and SARSTEDT, as well as from distributors including McKesson, Cardinal Health, Medline, Fisher Scientific, Avantor, and Henry Schein.
• The most important purchasing factors are tube type, required specimen volume, additive, material, closure, compatibility with laboratory instruments, regulatory status, and the supplier’s ability to maintain lot consistency and cold-chain or storage requirements.
• Hospitals, pediatric practices, laboratories, and mobile collection services should validate tube performance with their testing laboratory before changing products and should maintain documented purchasing, inventory, and quality-control procedures.

Pediatric blood collection requires supplies that are designed for small specimen volumes, limited venous access, and the special handling needs of infants and children. A tube that is appropriate for an adult phlebotomy procedure may be unsuitable for a premature infant, a child requiring repeated testing, or a laboratory assay that accepts only a small quantity of plasma or serum. For that reason, hospitals, physician offices, pediatric clinics, reference laboratories, and outpatient collection centers usually purchase specialized pediatric blood collection tubes rather than relying only on standard adult evacuated tubes.

In the United States, buyers can obtain pediatric blood collection tubes through two main channels. The first channel is direct purchasing from manufacturers that develop and produce collection systems. The second is purchasing through medical and laboratory distributors that carry multiple brands and can combine tubes with needles, lancets, microtainers, specimen labels, transport bags, and other supplies. Some organizations use both channels: a distributor for routine orders and a direct manufacturer relationship for contracts, validation support, or high-volume purchasing.

Common suppliers and brands in the U.S. market include Becton, Dickinson and Company, commonly known as BD; Greiner Bio-One; SARSTEDT; and several broad-line distributors such as McKesson, Cardinal Health, Medline, Fisher Scientific, Avantor, and Henry Schein. Product availability can vary by state, purchasing contract, laboratory system, and distributor inventory. A product listed in a national catalog may not be available for every account, so purchasers should confirm current stock, minimum order quantities, expiration dating, and shipping conditions before placing an order.

What Are Pediatric Blood Collection Tubes?

Pediatric blood collection tubes are small-volume specimen containers used to collect, transport, and prepare blood from infants and children. They may be designed for venous blood collection, capillary collection, or both, depending on the product. Some tubes are miniature versions of conventional evacuated tubes, while others are non-evacuated microtubes intended to receive blood from a heel stick, finger stick, butterfly collection, or syringe transfer.

The term “pediatric tube” can refer to several different products. A small tube with a serum Separator Gel is used for chemistry or serology testing. A tube containing ethylenediaminetetraacetic acid, or EDTA, is used for hematology tests such as a complete blood count. A Sodium Citrate tube is used for selected coagulation studies. A Heparin tube may be used for plasma chemistry or other assays. There are also specialized tubes for blood gases, trace elements, glucose, molecular testing, and newborn screening.

The correct tube is determined by the laboratory test, not simply by the patient’s age. Pediatric patients can require the same additive as adults, but the tube must often be available in a lower fill volume. This is particularly important in neonatal intensive care units, pediatric intensive care units, oncology services, and specialty clinics where blood loss from testing can accumulate over time.

Major U.S. Manufacturers of Pediatric Blood Collection Tubes

BD

BD is one of the best-known manufacturers of blood collection products in the United States. Its portfolio includes the BD Microtainer family and related Capillary Blood Collection products. These products are commonly used in pediatric and neonatal settings for small-volume capillary specimens. Depending on the specific catalog number, BD products may include tubes with serum, plasma, EDTA, Heparin, or other configurations.

BD Microtainer products are often purchased by hospitals, pediatric offices, urgent care centers, and clinical laboratories that already use BD needles, holders, and evacuated collection tubes. One advantage of purchasing from an established system manufacturer is the ability to standardize collection accessories, labels, tube racks, and staff training. Buyers should still review the exact product instructions because tube design, additive, fill volume, and specimen-processing requirements differ among catalog numbers.

BD products are sold through direct corporate contracts and through major U.S. distributors. Large health systems may receive contract pricing through a group purchasing organization, while smaller practices may purchase through a local medical distributor or laboratory supply catalog. When comparing prices, purchasers should include the cost of compatible lancets, transfer devices, specimen cups, racks, and shipping rather than comparing the tube price alone.

Greiner Bio-One

Greiner Bio-One is another major manufacturer with a presence in the U.S. laboratory market. Its MiniCollect line is associated with small-volume blood collection and is used for capillary or low-volume specimen collection in pediatric and other patients. Product configurations can include serum, lithium Heparin, and K2EDTA tubes, among others, depending on the market and application.

Greiner Bio-One’s products are distributed through laboratory and healthcare supply channels. Laboratories that use Greiner Bio-One’s VACUETTE system for adult blood collection may prefer to use MiniCollect products to maintain brand consistency. However, the important purchasing question is whether the pediatric tube is validated for the particular analyzer and test menu used by the facility. A compatible tube must produce acceptable results after centrifugation, separation, transport, and storage.

Greiner Bio-One also supplies related products such as capillary collection devices, safety accessories, and specimen handling products. This can be useful for organizations attempting to reduce the number of brands and vendors used across several departments.

SARSTEDT

SARSTEDT manufactures small-volume blood collection products, including its Microvette line. Microvette tubes are used in many laboratories for Capillary Blood Collection and may be available with serum, EDTA, Heparin, fluoride, or other additive configurations. Some versions are designed to support collection from the end or side of the tube, which may be useful for specific pediatric collection workflows.

SARSTEDT products are available from laboratory distributors and may also be obtained through institutional contracts. Because the company offers a broad range of specimen containers and collection systems, buyers may be able to consolidate pediatric tubes with urine, saliva, transport, and other laboratory supplies. As with all pediatric collection products, the buyer should confirm the intended collection method and the laboratory’s acceptance criteria before substituting one tube for another.

Other Specialized and Regional Manufacturers

In addition to the largest collection-system manufacturers, the U.S. market includes specialized manufacturers of capillary tubes, blood gas products, trace-element collection tubes, newborn screening cards, and microcollection containers. Some of these suppliers focus on a narrow laboratory application rather than offering a full line of Venipuncture supplies.

Availability may also come from regional distributors that sell private-label or specialty products. A private-label product can be suitable when it has appropriate regulatory documentation, consistent lot performance, and laboratory validation. However, purchasers should not assume that a private-label microtube is interchangeable with a branded tube simply because the container size appears similar.

Major U.S. Distributors That May Sell Pediatric Tubes

McKesson

McKesson is a major healthcare distributor serving hospitals, physician practices, pharmacies, and other healthcare organizations. Its medical and laboratory supply catalogs commonly include pediatric and Capillary Blood Collection products from leading manufacturers. Availability depends on the customer’s account, distribution center, contract terms, and regional inventory.

McKesson can be convenient for buyers that already purchase gloves, syringes, dressings, sharps containers, and other clinical supplies through the same account. The company’s distribution model may also support recurring orders and consolidated invoices. Buyers should check whether the listed product is sold by the case, box, or individual unit and whether a substitute-product policy could result in a different brand being shipped.

Cardinal Health

Cardinal Health is another large U.S. healthcare distributor that supplies hospitals, ambulatory centers, laboratories, and physician offices. Pediatric Microcollection Tubes may be available through its laboratory and medical supply channels, including products from established manufacturers.

For larger organizations, Cardinal Health may support supply agreements, electronic ordering, automated replenishment, and product standardization. A purchasing department should ask whether a tube is covered by an existing enterprise agreement and whether the agreement specifies a particular manufacturer or allows equivalent products. This distinction matters because laboratories may have validated only one brand or one catalog number.

Medline

Medline distributes a broad range of medical and laboratory supplies. Pediatric blood collection tubes may be available as branded products, Medline products, or products sourced through its laboratory supply portfolio. Medline is often used by outpatient practices and health systems that want one vendor for clinical consumables, infection prevention supplies, procedure products, and specimen collection items.

When buying from a broad-line distributor, the purchaser should review the product description carefully. Terms such as “micro,” “pediatric,” “capillary,” and “mini” are not always used consistently between manufacturers. The product description should identify the additive, nominal volume, tube material, closure type, collection method, and intended testing application.

Fisher Scientific

Fisher Scientific serves research laboratories, clinical laboratories, hospitals, universities, and biotechnology organizations. Its catalog commonly includes products from several blood collection manufacturers, including small-volume tubes and microcollection systems. Fisher can be especially useful for laboratories that need both clinical collection supplies and research-grade consumables.

Fisher’s catalog structure allows buyers to compare brands and package sizes, but product selection still requires technical review. A tube intended for clinical chemistry is not automatically suitable for hematology, coagulation, or trace-element testing. In addition, some products sold through laboratory catalogs may be intended for research use rather than routine clinical diagnosis. The product’s labeling and regulatory status should therefore be reviewed before purchase.

Avantor and VWR

Avantor, including the VWR distribution channel, supplies laboratory and healthcare organizations throughout the United States. Buyers may find pediatric tubes, microcollection products, specimen containers, racks, centrifuge accessories, and transport materials through its catalog.

Avantor and VWR are often useful for hospitals, academic medical centers, reference laboratories, and research institutions that purchase a wide variety of laboratory items. Their product range can make it easier to consolidate orders, but the same need for technical evaluation applies. A laboratory should verify whether the tube is approved or cleared for the intended clinical use and whether its performance has been assessed on the facility’s instruments.

Henry Schein

Henry Schein is a major distributor serving dental, medical, and specialty healthcare practices. Pediatric blood collection tubes may be available through its medical supply business, particularly for physician offices, pediatric practices, and outpatient clinics. Henry Schein may also offer related products such as pediatric needles, safety lancets, gloves, labels, and sharps containers.

Small practices should pay attention to package sizes and expiration dates. A clinic that performs only a few pediatric blood draws each week may spend more per tube when buying a small package, but it may reduce waste from expired inventory. Conversely, high-volume clinics may benefit from case quantities if they have adequate storage and predictable demand.

How to Identify the Correct Pediatric Tube

Choosing a supplier is only part of the purchasing process. The tube must match the test, collection technique, and laboratory Workflow. The following factors should be documented before an order is approved.

1. Additive: Determine whether the test requires serum, EDTA plasma, heparinized plasma, citrate plasma, fluoride-preserved blood, or another specimen type.

2. Collection volume: Confirm the minimum and maximum acceptable volume. A nominal tube capacity is not always the same as the laboratory’s minimum validated volume.

3. Collection method: Establish whether the tube is intended for capillary collection, venous collection, blood transferred from a syringe, or use with a specific collection device.

4. Patient population: Consider neonates, premature infants, children with difficult venous access, and patients requiring serial testing.

5. Specimen processing: Verify centrifugation speed, separation time, mixing requirements, Clotting Time, and storage conditions.

6. Instrument compatibility: Check whether the analyzer, automation line, centrifuge, and aliquoting equipment can accept the tube dimensions and closure.

7. Regulatory status: Review whether the product is labeled for clinical diagnostic use in the United States and whether the manufacturer provides the required documentation.

8. Lot and expiration control: Confirm that the supplier can provide sufficient shelf life and reliable lot information for quality-control records.

Important Product Categories

Serum and Serum Separator Microtubes

Serum microtubes are commonly used for chemistry, immunology, and selected serology tests. Some contain a Clot Activator, while others include a Separator Gel. A gel separator can help separate serum from cells after centrifugation, but performance may depend on the assay, specimen volume, centrifuge settings, and transport conditions.

Pediatric serum tubes are frequently used in outpatient clinics and hospital phlebotomy departments. Buyers should confirm whether the laboratory requires a plain tube, Clot Activator, or gel separator. A specimen collected in the wrong serum configuration may require recollection, which can be especially difficult for young patients.

EDTA Microtubes

EDTA tubes are generally associated with hematology testing, including complete blood counts and selected morphology or reticulocyte procedures. The blood-to-additive ratio and adequate mixing are important. Underfilling, clotting, excessive delay, or vigorous shaking can affect results.

Because pediatric specimens may be very small, staff should follow the manufacturer’s instructions for the minimum fill volume. The laboratory should also define procedures for rejecting clotted, hemolyzed, or insufficient specimens.

Heparin Microtubes

Heparin tubes are used for selected plasma chemistry tests and other laboratory applications. Lithium Heparin is common in clinical chemistry, but the appropriate additive depends on the test. Pediatric Heparin tubes may be available with or without Separator Gel.

Buyers should be cautious about substituting a Heparin tube from one manufacturer for another. Differences in gel, tube material, Heparin concentration, or surface treatment may affect certain assays.

Citrate and Blood Gas Products

Sodium Citrate tubes are used for coagulation testing and generally require a carefully controlled blood-to-additive ratio. Small-volume citrate products can be helpful in pediatrics, but not every coagulation analyzer or laboratory procedure accepts them. The laboratory director or technical supervisor should approve the product before routine use.

Blood gas collection may require specialized capillary tubes, balanced Heparin, or dedicated blood gas syringes. These products should not be selected solely based on their small size. Oxygen exposure, air bubbles, temperature, transport time, and analyzer requirements can all affect blood gas results.

Regulatory and Quality Considerations in the United States

U.S. purchasers should consider the regulatory classification and labeling of each product. The Food and Drug Administration regulates medical devices, including many blood collection tubes and specimen collection systems. A product’s intended use, labeling, manufacturer documentation, and applicable clearance or registration information should be reviewed by the organization’s quality or regulatory department.

Clinical laboratories operating under the Clinical Laboratory Improvement Amendments must maintain procedures that support accurate and reliable testing. Tube changes may require verification or validation under the laboratory’s quality system. The laboratory may need to assess Specimen Integrity, bias, precision, carryover, clotting, hemolysis, and analyzer compatibility before adopting a new tube.

The Clinical and Laboratory Standards Institute publishes widely used guidance for venous and Capillary Blood Collection, order of draw, specimen handling, and other laboratory processes. Organizations also commonly use guidance from the Centers for Disease Control and Prevention, the Occupational Safety and Health Administration, professional laboratory associations, and accreditation bodies.

OSHA’s Bloodborne Pathogens Standard is relevant to the safe handling of blood collection equipment and contaminated materials. Pediatric tubes should be used with appropriate personal protective equipment, sharps Safety Procedures, leak-resistant transport packaging, and approved sharps disposal systems. Purchasing teams should evaluate the tube as part of the entire collection process rather than as an isolated item.

Market and Demand Considerations

The need for pediatric blood collection products is supported by the scale of pediatric healthcare in the United States. The U.S. Census Bureau has consistently reported that children under 18 represent roughly one-fifth of the U.S. population, although the exact share changes by year. The United States also records approximately 3.5 to 4 million births annually, creating a substantial need for neonatal bilirubin, glucose, blood gas, newborn screening, and other testing services.

The Centers for Disease Control and Prevention’s newborn screening programs test millions of newborns each year for congenital, metabolic, endocrine, hemoglobin, and other conditions. Many newborn screening procedures use dried blood spot cards rather than ordinary collection tubes, but hospitals and laboratories still require microcollection devices for confirmatory and related testing.

Hospital utilization data from federal sources, including the Healthcare Cost and Utilization Project, show that children account for millions of emergency department visits and hospital encounters in the United States each year. Not every encounter requires blood collection, but the volume illustrates why pediatric-compatible supplies are needed across emergency departments, inpatient units, outpatient clinics, and specialty services.

Demand is also influenced by the expansion of Point-Of-Care Testing, home-based healthcare, pediatric oncology, chronic disease monitoring, and laboratory medicine protocols designed to reduce blood loss. A small-volume tube may support a lower-volume analyzer, but it does not eliminate the need for careful collection technique and appropriate laboratory oversight.

How to Compare Suppliers

Price is important, but it should not be the only purchasing criterion. A low unit price can become expensive if the product has a short expiration period, high breakage, inconsistent availability, or poor compatibility with the laboratory’s Workflow. Buyers should compare the total cost of ownership.

1. Unit and case price: Compare the price per usable tube, including case quantity, shipping, handling, and contract discounts.

2. Availability: Ask whether the supplier maintains domestic inventory and how it manages backorders or substitutions.

3. Expiration dating: Request the minimum shelf life guaranteed at shipment, especially for low-volume pediatric practices.

4. Product consistency: Determine whether the supplier can provide the same manufacturer and catalog number for recurring orders.

5. Technical support: Evaluate access to instructions for use, certificates, safety documentation, and validation information.

6. Shipping conditions: Verify whether the product requires temperature-controlled transportation or special protection from freezing and heat.

7. Order flexibility: Compare minimum order quantities, standing orders, emergency delivery, and automatic replenishment options.

8. Recall communication: Confirm how the distributor communicates recalls, field corrections, and lot-specific notices.

Purchasing Through a Group Purchasing Organization

Many U.S. hospitals and health systems purchase medical supplies through group purchasing organizations, often called GPOs. GPO contracts can provide negotiated pricing and standardized product lists. They may also simplify contract administration and reduce the number of individual vendor relationships.

However, a GPO contract does not replace clinical evaluation. A pediatric unit may need a tube that is not on the standard adult collection contract. Before switching products, the laboratory, nursing department, infection prevention team, Supply Chain department, and clinical leadership should review the proposed change.

Contract language should be examined for product substitutions. Some agreements allow the distributor to ship an equivalent product during a shortage. If the laboratory requires a specific tube, the purchasing organization should establish a no-substitution rule or a formal approval process for alternatives.

Inventory Management for Pediatric Tubes

Pediatric collection tubes are often used in lower quantities than adult tubes, which increases the risk of unnoticed expiration. A basic inventory system should track catalog number, manufacturer, additive, lot number, expiration date, storage location, par level, and reorder point.

First-expiring, first-out rotation is appropriate for most nonperishable collection tubes. Storage areas should remain clean, dry, and within the manufacturer’s stated temperature range. Boxes should not be stored where they can be crushed, exposed to moisture, or contaminated by chemicals. Staff should inspect packaging before use and quarantine damaged or questionable products.

Demand forecasting should account for seasonal changes, vaccination and respiratory illness activity, school physicals, neonatal census, oncology schedules, and laboratory test volume. A hospital may need greater stock during respiratory virus seasons or periods of increased emergency department activity. A small pediatric office may require a smaller standing order with rapid replenishment capability.

Questions to Ask Before Ordering

Before selecting a U.S. supplier, a purchasing team can ask the following questions:

1. Is the tube intended for the exact specimen type and test being performed?

2. Is the product labeled for clinical diagnostic use in the United States?

3. What is the recommended and minimum collection volume?

4. Can the laboratory use the tube with its current centrifuge and analyzer?

5. What is the expected shelf life when the product is shipped?

6. Does the distributor guarantee a specific manufacturer and catalog number?

7. Are there restrictions on transferring blood from a syringe or collecting by capillary technique?

8. How are backorders, substitutions, recalls, and damaged shipments handled?

9. Can the supplier provide lot documentation and technical instructions?

10. What quantity is appropriate for the organization’s monthly use?

Best Overall Buying Strategy

For most U.S. healthcare organizations, the best purchasing strategy is to begin with the laboratory’s testing requirements and then identify two or three qualified supply channels. A large hospital may compare direct contracts with BD, Greiner Bio-One, or SARSTEDT against pricing from Cardinal Health, McKesson, Medline, Fisher Scientific, or Avantor. A pediatric practice may prefer a distributor that provides small quantities, predictable shipping, and related phlebotomy supplies.

Organizations should avoid choosing a tube solely because it is the least expensive or because it resembles an existing product. The collection tube affects specimen quality, laboratory Workflow, staff training, and patient experience. In pediatric care, a failed collection can result in an additional needle stick, delayed diagnosis, increased anxiety, and avoidable blood loss.

A formal evaluation should include a product comparison, laboratory approval, staff training, and a defined transition date. During the transition, staff should know how to identify the old and new products, what tests are approved for each tube, and which tubes should not be mixed in the same Workflow. Any change should be monitored through recollection rates, rejected specimens, hemolysis rates, clotting incidents, turnaround time, and user feedback.

Conclusion

Several major U.S. manufacturers and distributors sell pediatric blood collection tubes. BD offers the widely used Microtainer family, Greiner Bio-One supplies MiniCollect products, and SARSTEDT provides Microvette and related microcollection systems. Hospitals and clinics can also purchase these and other brands through McKesson, Cardinal Health, Medline, Fisher Scientific, Avantor and VWR, Henry Schein, group purchasing organizations, and regional laboratory distributors.

The most suitable supplier depends on the organization’s test menu, patient population, purchasing volume, contract arrangements, inventory capacity, and laboratory validation requirements. A pediatric tube should be selected by additive, specimen volume, collection method, and instrument compatibility rather than by general product name. Buyers should also evaluate regulatory documentation, shelf life, shipping reliability, lot control, technical support, and substitution policies.

Because tube performance can vary by manufacturer and assay, the final decision should be made jointly by Supply Chain personnel and qualified laboratory or clinical leaders. With appropriate validation and inventory controls, U.S. healthcare organizations can obtain pediatric blood collection tubes that support accurate testing while helping reduce unnecessary specimen volume and repeat collections.
