Pediatric Blood Collection Tubes: U.S. Suppliers, Types, and Purchasing Guide

Summary

• U.S. buyers can purchase pediatric blood collection tubes from manufacturers and distributors such as BD, Greiner Bio-One, Cardinal Health, McKesson Medical-Surgical, Medline, and Fisher Scientific.
• The most important purchasing factors are tube type, specimen volume, additive, testing requirements, device compatibility, regulatory status, shelf life, and supply reliability.
• Microcollection Tubes, pediatric serum tubes, EDTA tubes, Heparin tubes, and specialty trace-element tubes are commonly used for children, but the correct product depends on the laboratory’s validated testing procedures.

Pediatric blood collection requires equipment designed to obtain an accurate specimen while minimizing discomfort and blood loss. For hospitals, physician offices, pediatric clinics, outpatient laboratories, Mobile Phlebotomy services, and research facilities, the choice of blood collection tube is an important purchasing decision. Pediatric tubes are generally smaller than standard adult tubes and are designed for low-volume collection, capillary sampling, or both.

In the United States, buyers can source pediatric blood collection tubes directly from manufacturers, through national medical-surgical distributors, from laboratory supply companies, and through regional healthcare purchasing organizations. Commonly available brands and distribution channels include BD, Greiner Bio-One, Cardinal Health, McKesson Medical-Surgical, Medline, Fisher Scientific, and other authorized laboratory suppliers. Some suppliers sell their own private-label products, while others distribute tubes manufactured by established diagnostic companies.

The market is broad, but not every “pediatric tube” is interchangeable. Tubes differ according to specimen type, additive, fill volume, closure color, material, testing application, and whether they are intended for venous or capillary blood. A tube that works for a complete blood count may be unsuitable for coagulation testing, chemistry, blood gas analysis, or trace-element testing.

What Are Pediatric Blood Collection Tubes?

Pediatric blood collection tubes are small-volume tubes used to collect blood from infants, children, and patients for whom a standard adult tube would remove an unnecessarily large amount of blood. They may be used with a heel-stick or finger-stick collection device, a small-gauge needle, a butterfly set, or a pediatric blood collection system.

Many pediatric tubes are Microcollection Tubes. These products often hold approximately 0.25 to 1.0 milliliter of blood, although actual capacity varies by product and test. Some pediatric venous tubes have capacities of approximately 1 to 3 milliliters. By comparison, common adult evacuated tubes may collect roughly 3 to 10 milliliters, depending on the tube and laboratory application.

Small-volume tubes can be particularly important in neonatal and pediatric care. A 2023 report from the Centers for Disease Control and Prevention estimated that approximately 3.6 million births occurred in the United States in 2022. Every newborn may require screening or diagnostic testing, and many neonatal intensive care patients need repeated laboratory evaluations. In these settings, reducing unnecessary blood loss is a clinical and operational priority.

The World Health Organization has also emphasized the importance of minimizing blood loss from pediatric and neonatal patients. Although exact allowable blood-loss limits depend on the child’s age, weight, clinical condition, and treatment environment, small-volume collection systems help laboratories and clinicians work within those limits.

Leading U.S. Suppliers and Distribution Channels

BD

BD, formerly known as Becton, Dickinson and Company, is one of the best-known manufacturers of blood collection products in the United States. Its product portfolio includes evacuated blood collection tubes, microcollection containers, Capillary Blood Collection products, needles, safety devices, and specimen-management products.

Hospitals and laboratories commonly evaluate BD pediatric and microcollection products when they want to standardize collection supplies across multiple departments. BD products are often available through large medical distributors, group purchasing organizations, and laboratory supply catalogs. Depending on the product line, buyers may find tubes intended for hematology, chemistry, blood banking, glucose testing, or other applications.

When purchasing BD pediatric tubes, procurement teams should verify the exact product number rather than relying only on the color of the cap. Tube colors may follow common conventions, but color coding can vary by manufacturer and product family. The buyer should confirm the additive, nominal draw volume, specimen type, and instrument compatibility before placing an order.

Greiner Bio-One

Greiner Bio-One is another major supplier of blood collection tubes used by U.S. laboratories and healthcare organizations. The company is widely associated with VACUETTE blood collection systems, including pediatric and low-volume tubes, capillary collection products, and accessories.

Greiner’s product range may include tubes for serum, plasma, hematology, coagulation, and specialty testing. Its products are distributed in the United States through laboratory supply companies, healthcare distributors, and direct institutional purchasing arrangements.

Greiner Bio-One tubes are often considered by laboratories that want an alternative to other major evacuated tube brands or that use analyzers validated with Greiner products. Buyers should examine whether the tube is intended for venous blood, capillary blood, or a particular collection device. A pediatric tube designed for capillary collection may not perform identically when used with a venous draw.

Cardinal Health

Cardinal Health is one of the largest healthcare distribution companies in the United States. It supplies hospitals, ambulatory surgery centers, physician practices, laboratories, pharmacies, and other healthcare organizations. Cardinal Health distributes products from multiple manufacturers and also offers private-label medical products in some categories.

For organizations already using Cardinal Health as a primary distributor, purchasing pediatric blood collection tubes through its medical-surgical catalog can simplify ordering, invoicing, inventory management, and shipment consolidation. Depending on the account and product category, buyers may find tubes from BD, Greiner Bio-One, and other manufacturers.

Cardinal Health is especially relevant for large health systems that want to manage pediatric tubes alongside needles, lancets, syringes, specimen bags, labels, sharps containers, and personal protective equipment. Consolidating these products can reduce the number of purchase orders and deliveries, although the lowest unit price is not always the same as the lowest total cost.

McKesson Medical-Surgical

McKesson Medical-Surgical is another major U.S. distributor that supplies laboratory and phlebotomy products. Its catalog typically includes blood collection tubes, microcollection products, lancets, safety needles, butterfly sets, specimen transport supplies, and laboratory consumables.

McKesson is commonly used by physician offices, clinics, hospitals, home healthcare organizations, and independent laboratories. Buyers may find both nationally recognized brands and private-label options. Pediatric tubes are often listed by specimen type, tube additive, cap color, draw volume, and packaging quantity.

McKesson can be a practical source for smaller practices that do not have the purchasing volume to negotiate directly with a manufacturer. However, product availability may vary by distribution center, contract, and regional inventory. Practices should confirm whether a listed product is in stock, backordered, substituted, or subject to minimum-order requirements.

Medline

Medline is a large medical-supply manufacturer and distributor serving hospitals, clinics, laboratories, long-term-care facilities, and other Healthcare Providers. Its catalog includes phlebotomy supplies, specimen collection products, safety devices, exam gloves, procedure kits, and laboratory accessories.

Medline may offer pediatric and Microcollection Tubes under its own brand or distribute products made by other manufacturers. Its value for healthcare organizations often comes from broad product availability and the ability to combine several categories of supplies in one purchasing program.

When reviewing Medline pediatric tubes, purchasers should read the technical description carefully. A product labeled “microtainer,” “microcollection tube,” or “pediatric tube” may have a different intended use, fill volume, or additive from another product with a similar name. The manufacturer’s instructions for use should be reviewed before clinical adoption.

Fisher Scientific

Fisher Scientific is a major laboratory supply distributor serving clinical laboratories, academic institutions, biotechnology companies, hospitals, and research organizations. Its catalog includes pediatric blood collection tubes from several manufacturers, along with centrifuge products, pipettes, specimen containers, labels, transport supplies, and laboratory safety equipment.

Fisher Scientific is particularly useful for laboratories that need to compare brands or source specialty tubes. For example, a laboratory may use standard pediatric EDTA tubes for hematology while also purchasing low-volume serum tubes, Heparin tubes, or trace-element tubes for specialized testing.

Research institutions may also prefer Fisher Scientific because its catalog supports both clinical and nonclinical workflows. Nevertheless, research-use-only products must not be substituted for clinical diagnostic products unless the intended use, regulatory status, and laboratory procedures permit that application.

Regional Medical and Laboratory Distributors

Regional distributors remain important suppliers for pediatric practices and community laboratories. These companies may serve a particular state or group of states and can sometimes offer more responsive customer service, local inventory, or customized delivery schedules.

Some regional distributors specialize in laboratory products, while others focus on general medical supplies. Buyers should ask whether the distributor is authorized to sell the product, whether it maintains appropriate storage conditions, and how it handles lot tracking, recalls, damaged goods, and expiration-date concerns.

Regional distributors can also help smaller facilities obtain mixed orders. A pediatric clinic may need only several cases of tubes per year, making a local distributor a useful source when national suppliers impose case-pack requirements or have lengthy lead times.

Common Types of Pediatric Blood Collection Tubes

EDTA Microcollection Tubes

EDTA tubes are commonly used for hematology testing, including complete blood counts. EDTA prevents clotting by binding calcium. Pediatric EDTA tubes are frequently available in purple or lavender-cap formats, although cap colors should never be the only basis for identification.

These tubes may be used for hemoglobin, hematocrit, red blood cell indices, white blood cell counts, platelet counts, and other hematology procedures. The correct blood-to-additive ratio is important. Underfilling, overfilling, inadequate mixing, or clot formation can lead to rejected specimens or inaccurate results.

Serum and Serum Separator Tubes

Pediatric serum tubes are used for chemistry, immunology, serology, and selected hormone or therapeutic-drug tests. Some include a Clot Activator, while others include a gel separator. The tube may be used for a small-volume venous sample or capillary specimen, depending on the manufacturer’s instructions.

Serum separator tubes can reduce handling time by separating serum from the clot after centrifugation. However, laboratories should validate the product with their analyzers and test menu. Gel composition, sample volume, centrifugation requirements, and possible interference can differ between product lines.

Heparin Tubes

Heparin tubes are commonly used to obtain plasma for chemistry testing. Lithium Heparin is frequently used, although the appropriate formulation depends on the laboratory test. Pediatric Heparin tubes may be green-cap or contain another manufacturer-specific color designation.

Heparin tubes can be useful when rapid plasma processing is preferred or when a laboratory method requires plasma rather than serum. Buyers should ensure that the selected tube does not contain an additive that interferes with the intended test. For example, some tests require a specific type of Heparin, while others may not accept heparinized specimens at all.

Coagulation Tubes

Sodium Citrate tubes are used for coagulation testing, including Prothrombin Time and Activated Partial Thromboplastin Time. These tubes are commonly associated with light-blue caps. Pediatric coagulation tubes may be available in reduced-volume formats, but the required blood-to-citrate ratio remains critical.

A tube that is substantially underfilled may produce an invalid result because the ratio of blood to Anticoagulant is incorrect. This is one reason pediatric coagulation collection requires careful attention to the manufacturer’s minimum fill line and the laboratory’s acceptance criteria.

Glucose and Specialty Tubes

Some pediatric collection tubes contain Sodium Fluoride, Potassium Oxalate, or another additive intended to preserve glucose or support a specialized test. Other tubes are designed for lead, trace-element, Toxicology, Blood Culture, or molecular testing.

Lead and trace-element testing requires particular attention to contamination control. A standard tube may contain trace amounts of metals or other substances that can affect results. Buyers should select a tube specifically cleared or validated for the intended trace-element test and should follow the laboratory’s collection order and contamination-prevention procedures.

How to Compare Suppliers Before Ordering

Confirm the Intended Clinical Use

The first purchasing question should be: What test or group of tests will be performed? A tube for a complete blood count is different from a tube for a coagulation panel, Blood Culture, Chemistry Test, or lead screening. The laboratory should identify the required specimen type and additive before comparing prices.

Review Volume and Minimum Fill Requirements

Nominal tube capacity does not always equal the minimum volume required for testing. A tube may hold 0.5 milliliter but require a particular fill volume for reliable processing. The laboratory should compare the tube’s draw volume with the analyzer’s dead volume, repeat-testing needs, and sample volume requirements.

This issue is especially important in neonatal care. A tube that appears small may still be too large for a very-low-birth-weight infant, while an extremely small tube may not provide enough specimen for the laboratory’s Workflow.

Check Regulatory and Quality Information

Clinical blood collection tubes sold in the United States are generally regulated as medical devices. Depending on the product and intended use, the manufacturer may identify a Food and Drug Administration clearance, registration, listing, or another applicable regulatory pathway. Buyers should request current regulatory and quality documentation when necessary.

Purchasers should also review certificates of analysis when available, lot information, quality-system certifications, and the manufacturer’s instructions for use. ISO 13485 certification can indicate that a manufacturer operates a medical-device quality-management system, but certification alone does not prove that a particular tube is suitable for every laboratory test.

Evaluate Compatibility With Laboratory Instruments

A pediatric tube must be compatible with the laboratory’s centrifuges, racks, carriers, aliquoting systems, barcode printers, automation tracks, and analyzers. Some small tubes require adapters or special racks. Others may not be accepted by automated systems designed for adult tubes.

Before switching brands, the laboratory should determine whether the tube can be loaded safely, whether the barcode can be scanned, whether the tube fits the centrifuge rotor, and whether the analyzer recognizes the container. An inexpensive tube can create significant costs if it requires manual processing or causes frequent Specimen Rejection.

Compare Total Cost Rather Than Unit Price

The purchase price is only one component of the total cost. Other factors include shipping, minimum-order quantities, storage space, special racks, adapters, labels, waste, expired inventory, specimen recollection, and staff time.

For example, a tube costing a few cents less may not be financially beneficial if it has a short remaining shelf life or requires a separate ordering process. Hospitals should also consider whether a supplier offers standing orders, automatic replenishment, electronic purchasing integration, and emergency delivery.

U.S. Purchasing Considerations

Distributor Contracts and Group Purchasing

Many U.S. hospitals buy through group purchasing organizations or negotiated distributor contracts. These agreements may provide discounted pricing, standardized products, and volume-based rebates. However, a contracted product may not always be the best clinical choice for every pediatric department.

Clinical engineering, laboratory leadership, infection prevention, nursing, and supply-chain personnel should participate in product evaluation. A purchasing decision should balance contract pricing with specimen quality, patient safety, staff training, and laboratory validation requirements.

Inventory and Backorder Planning

Blood collection tubes are consumable products, and supply interruptions can affect patient care. The Covid-19 pandemic demonstrated how quickly medical and laboratory supply chains can experience shortages. In 2020 and 2021, hospitals reported disruptions involving collection tubes, swabs, reagents, personal protective equipment, and other diagnostic supplies.

Facilities should establish par levels based on average usage, seasonal demand, supplier lead time, and emergency requirements. A common approach is to maintain a primary product and a preapproved alternative. However, the alternative should be evaluated and validated before an emergency occurs.

Buyers should monitor lot numbers and expiration dates using a first-expire, first-out system. Excessive purchasing may appear prudent during a shortage, but overstock can lead to expired tubes, wasted money, and storage problems.

Packaging and Storage

Pediatric tubes may be sold in boxes, bags, trays, or cases. Packaging quantities vary substantially. A small pediatric office may prefer smaller boxes to reduce expiration waste, while a large hospital may favor case quantities for lower per-unit pricing.

Most blood collection tubes should be stored in a clean, dry environment within the temperature range specified by the manufacturer. Exposure to excessive heat, cold, moisture, sunlight, or mechanical damage can affect product performance. Tubes should remain in their original packaging until needed, and damaged or cracked tubes should be removed from inventory.

Important Standards for Collection and Handling

Tube selection is only one part of specimen quality. The Clinical and Laboratory Standards Institute publishes widely used guidance for venous and Capillary Blood Collection, including recommendations related to patient identification, order of draw, tube mixing, transport, and specimen handling.

Capillary collection requires a suitable puncture site and an appropriate collection sequence. Excessive squeezing of the puncture site may cause tissue-fluid contamination or hemolysis. The first drop may need to be removed depending on the collection procedure and test requirements. Staff should follow the tube manufacturer’s instructions and the laboratory’s approved procedure.

After collection, additive tubes generally require gentle inversion. Vigorous shaking can cause hemolysis, while inadequate mixing can permit clot formation. The number of inversions varies by tube type and manufacturer. Pediatric patients may also require shorter processing times because small specimens leave less opportunity for repeat analysis.

Specimen labeling is equally important. The label should be applied according to facility policy and should include the required patient identifiers, collection date and time, collector information, and accession or encounter information when applicable. Misidentified specimens are a major patient-safety concern regardless of tube brand.

Questions to Ask a Pediatric Tube Supplier

1. Is the product intended for capillary collection, venous collection, or both?
2. What is the nominal draw volume and the minimum acceptable fill volume?
3. What additive does the tube contain, and what tests is it validated for?
4. Is the tube intended for clinical diagnostic use in the United States?
5. What are the product’s storage conditions and shelf life?
6. What is the minimum order quantity and typical lead time?
7. Can the supplier provide lot tracking and expiration-date information?
8. Is the tube compatible with the facility’s centrifuges, racks, analyzers, and automation systems?
9. Are adapters or special carriers required?
10. What is the supplier’s policy for damaged, short-dated, recalled, or backordered products?

Recommended Supplier Selection Process

A structured evaluation helps prevent purchasing errors. The laboratory can begin by listing the pediatric tests performed, the required specimen types, the average monthly volume, and the smallest patient populations served. The team can then identify candidate products from two or more suppliers.

Next, the laboratory should compare technical specifications, pricing, delivery terms, and regulatory documentation. Samples should be evaluated in the actual clinical Workflow. This may include testing the tubes with routine analyzers, centrifuges, barcode systems, pneumatic tube transport, and manual processing procedures.

Validation should include specimen quality, clotting, hemolysis, gel performance, fill-volume adequacy, barcode readability, and compatibility with reference intervals or established laboratory procedures. If results from a new tube are compared with results from a current tube, the laboratory should use an appropriate verification plan.

Once a product is approved, the facility should update its supply catalog, collection manuals, electronic ordering system, training materials, and nursing or phlebotomy procedures. Staff should be informed about differences in cap color, minimum fill lines, inversion requirements, and collection order.

Which Supplier Is Best for Different Buyers?

Large hospitals and integrated health systems may benefit from purchasing BD or Greiner Bio-One products through a national distributor such as Cardinal Health, McKesson Medical-Surgical, or Medline. This approach can support systemwide standardization and centralized inventory control.

Independent laboratories may prefer Fisher Scientific or a specialized laboratory distributor because these channels often provide access to multiple brands and specialty tubes. A laboratory with unusual testing requirements may need to source products from more than one manufacturer.

Pediatric offices and outpatient clinics may value a distributor that offers small case quantities, dependable delivery, and customer support. McKesson, Medline, Cardinal Health, and regional medical suppliers may be practical options depending on contract pricing and local availability.

Neonatal intensive care units and children’s hospitals should prioritize low-volume performance, specimen conservation, instrument compatibility, and clinical validation. The best supplier is not necessarily the one offering the lowest listed price. Reliability, technical support, and the ability to maintain continuity during shortages may be more important.

Final Considerations for U.S. Buyers

Several established companies sell pediatric blood collection tubes in the United States. BD and Greiner Bio-One are prominent manufacturers. Cardinal Health, McKesson Medical-Surgical, Medline, and Fisher Scientific are major distribution channels that may carry products from these and other manufacturers. Regional laboratory and medical suppliers can also be valuable sources, especially for smaller practices or facilities requiring personalized service.

The correct product depends on the patient, collection method, blood volume, additive, laboratory test, and equipment used for processing. Buyers should avoid selecting tubes based only on brand name, color, or price. They should confirm the intended use, review the manufacturer’s instructions, verify regulatory status, and involve laboratory professionals in the evaluation.

For pediatric and neonatal patients, blood conservation should remain central to the purchasing decision. A properly selected low-volume tube can help reduce unnecessary blood loss, improve specimen quality, and limit recollection. A carefully managed supplier relationship can also protect the facility from shortages, expired inventory, and disruptive product substitutions.
