Top U.S. Suppliers of Red-Top Blood Collection Tubes: Brands, Pricing, and Buying Guide
Summary
- Major U.S. suppliers of red-top blood collection tubes include BD, Greiner Bio-One, Cardinal Health, McKesson Medical-Surgical, Medline, Fisher Scientific, Avantor, and Thermo Fisher Scientific.
- Red-top tubes are generally used for serum testing and may be manufactured from glass or plastic, with or without Clot Activator; the correct choice depends on the laboratory’s test requirements and analyzer validation.
- Healthcare purchasers should compare tube specifications, certifications, packaging, minimum order quantities, shipping conditions, back-order history, and total acquisition cost before selecting a supplier.
Red-top blood collection tubes remain a standard item in many hospitals, physician offices, independent laboratories, reference laboratories, urgent care centers, Mobile Phlebotomy services, and research facilities across the United States. These tubes are commonly associated with serum collection and are used for a broad range of chemistry, serology, immunology, Therapeutic Drug Monitoring, and other laboratory procedures.
Although the red-top tube is familiar to experienced phlebotomists, purchasing the correct product is more complicated than simply ordering a tube with a red cap. Manufacturers offer red-top tubes in different materials, sizes, draw volumes, interior treatments, and packaging configurations. Some contain no additive, while others include a Clot Activator. A facility that substitutes one version for another without checking laboratory requirements may create specimen quality problems, rejected samples, or inaccurate Test Results.
In the United States, red-top blood collection tubes are sold through several types of suppliers. These include original manufacturers, national medical-surgical distributors, laboratory supply companies, group purchasing organizations, and specialized diagnostic product distributors. The most recognizable names include BD, Greiner Bio-One, Cardinal Health, McKesson Medical-Surgical, Medline, Fisher Scientific, Avantor, and Thermo Fisher Scientific. Availability can vary by state, contract, product size, manufacturer, and inventory conditions.
What Are Red-Top Blood Collection Tubes?
A red-top blood collection tube is generally designed to collect whole blood that will clot so the laboratory can separate serum. Unlike lavender-top tubes, which contain EDTA for hematology testing, or light-blue tubes, which contain Sodium Citrate for coagulation studies, conventional red-top tubes typically do not contain an anticoagulant.
There are two broad categories of red-top tubes commonly encountered in U.S. purchasing:
-
Plain red-top tubes: These tubes contain no Anticoagulant and no Clot Activator. They may be made from glass or plastic and are used when a laboratory requires naturally clotted blood or a specimen free of clot-activator material.
-
Red-top tubes with Clot Activator: These plastic tubes contain a substance that accelerates clot formation. They are sometimes identified as serum tubes, red/gray tubes, or other manufacturer-specific designs, so purchasers must read the product description carefully.
The color of the cap is not sufficient to determine the tube’s contents. Cap colors are widely standardized in clinical practice, but variations exist among manufacturers and product families. A red cap may identify a plain serum tube, a serum tube with Clot Activator, or a tube intended for a specialized application. The package insert, manufacturer catalog number, and laboratory procedure should always control the purchasing decision.
Leading U.S. Suppliers of Red-Top Tubes
BD
BD is one of the largest and best-known manufacturers of blood collection products in the United States. Its Vacutainer product family is widely used in hospitals, physician offices, and clinical laboratories. BD offers multiple serum collection tube configurations, including products with red caps, different draw volumes, plastic or glass construction, and clot-activator options.
BD products are commonly purchased directly through institutional contracts or indirectly through distributors such as McKesson, Cardinal Health, Medline, and laboratory supply companies. The company’s broad product portfolio makes it an important option for facilities that want to standardize collection tubes, needles, holders, transfer devices, and safety products from one manufacturer.
When evaluating BD red-top tubes, purchasers should verify the exact catalog number, tube material, nominal draw volume, sterility status, expiration date, and whether the tube contains Clot Activator. A product described generally as a “red-top tube” may not be interchangeable with another BD serum tube.
Greiner Bio-One
Greiner Bio-One is another major manufacturer of evacuated blood collection systems sold in the United States. Its VACUETTE product line includes serum tubes and other specimen collection tubes. Depending on the specific product, red-top or serum collection tubes may be available with no additive or with Clot Activator.
Greiner Bio-One products are used by hospitals, outpatient laboratories, research organizations, and large medical practices. The company emphasizes standardized evacuated collection systems and offers tubes in a variety of sizes. Purchasers may find Greiner tubes through direct sales representatives, national distributors, laboratory suppliers, and regional medical supply vendors.
Because product terminology can vary, a buyer should confirm whether a Greiner tube is intended for serum, plasma, trace-element testing, molecular testing, or another application. The red-cap color should be considered together with the printed label, additive description, and package insert.
Cardinal Health
Cardinal Health is a major U.S. healthcare distributor and also offers medical products under its own brand families. Hospitals, ambulatory surgery centers, physician groups, laboratories, and long-term care organizations frequently use Cardinal Health as a primary source for phlebotomy supplies.
Cardinal Health may provide red-top tubes manufactured by BD, Greiner Bio-One, or other approved suppliers, as well as private-label or house-brand alternatives in some categories. Its value to purchasers is often based on distribution reach, contract pricing, consolidated invoicing, and the ability to order tubes along with needles, syringes, gloves, disinfectants, specimen bags, and other consumables.
Organizations purchasing through Cardinal Health should review the manufacturer and catalog number shown on the quote or purchase order. If a laboratory has validated a specific tube, switching to a distributor-branded alternative may require laboratory approval before implementation.
McKesson Medical-Surgical
McKesson Medical-Surgical is one of the largest distributors of medical supplies in the United States. It supplies products to hospitals, clinics, laboratories, physician offices, home health agencies, and other healthcare organizations. Red-top blood collection tubes are commonly available through McKesson’s laboratory and phlebotomy product categories.
McKesson can be useful for facilities that want to combine phlebotomy purchasing with broader medical-surgical procurement. A single order may include serum tubes, EDTA tubes, citrate tubes, alcohol pads, tourniquets, gauze, labels, sharps containers, and specimen transport materials.
Availability depends on the customer’s account, regional distribution center, contract terms, and manufacturer inventory. Buyers should ask whether the quoted item is a regular-stock product, a special-order product, or a substitute. They should also determine whether the shipment will be split across multiple fulfillment centers, since split shipments can complicate inventory control.
Medline Industries
Medline Industries supplies hospitals, outpatient centers, physician practices, laboratories, nursing facilities, and other Healthcare Providers. The company distributes a wide range of blood collection and specimen management products, including serum tubes and related accessories.
Medline is often attractive to buyers seeking private-label options, standardized packaging, or a consolidated supply contract. Depending on the product, a red-top tube may be sold under the Medline brand or sourced from an established manufacturer. The purchaser should not rely on the brand name alone; the actual tube specifications must be checked.
Medline and other large distributors may offer tiered pricing based on annual usage. A clinic purchasing several hundred tubes per month may receive a different price than a small office purchasing one case every few months. However, lower unit pricing may be offset by case-pack requirements, freight charges, storage costs, or expiration-related waste.
Fisher Scientific
Fisher Scientific is a major laboratory supply distributor serving clinical laboratories, biotechnology companies, universities, pharmaceutical manufacturers, government agencies, and research institutions. Its catalog commonly includes serum collection tubes from several manufacturers, including BD, Greiner Bio-One, and other laboratory brands.
Fisher Scientific is particularly useful for laboratories that need to compare multiple tube designs or purchase clinical and research supplies through the same procurement system. Red-top tubes may be listed under serum collection tubes, evacuated blood collection tubes, diagnostic specimen containers, or laboratory plasticware categories.
Research buyers should be especially careful when selecting a product from a broad laboratory catalog. A tube may be suitable for general serum collection but not approved for a particular clinical assay. For regulated clinical testing, the laboratory director or quality department should confirm that the selected tube is acceptable for the intended procedure.
Avantor and VWR
Avantor supplies laboratory, biopharmaceutical, healthcare, and research organizations. VWR, which operates within the Avantor portfolio, is a familiar source for laboratory consumables and specimen collection products. Its customers include universities, hospitals, pharmaceutical companies, contract research organizations, and industrial laboratories.
Avantor and VWR may offer red-top tubes from multiple manufacturers, including standard evacuated serum tubes and specialized tubes for research workflows. Their distribution model can be helpful when a purchaser needs tubes along with pipettes, centrifuge supplies, preservatives, labels, transport materials, and laboratory safety products.
Before ordering, customers should distinguish between products intended for human diagnostic use and those intended only for research use. A research-use-only tube may not be appropriate for patient testing unless the laboratory has completed the necessary evaluation and documentation.
Thermo Fisher Scientific
Thermo Fisher Scientific serves clinical laboratories, research laboratories, hospitals, pharmaceutical companies, universities, and government institutions. Through its laboratory supply and diagnostic product channels, it may offer serum collection tubes and related phlebotomy products from different manufacturers.
Thermo Fisher can be a practical supplier for laboratories that already purchase centrifuges, pipette supplies, specimen processing products, reagents, or research consumables from the company. Buyers should still verify whether the tube is a clinical collection device, a research product, or a general laboratory container.
The distinction matters because product labeling, quality documentation, intended use, and regulatory status may differ. A tube used for patient specimens should be compatible with the laboratory’s validated Workflow and should meet the facility’s requirements for traceability and Quality Control.
Other Sources for Red-Top Tubes
In addition to the major manufacturers and national distributors, red-top tubes may be available from regional medical suppliers, laboratory equipment dealers, group purchasing organizations, specialty diagnostic distributors, and online business-to-business marketplaces. Some physician-office supply companies also sell smaller case quantities to independent practices.
Regional suppliers can sometimes provide more personalized service, faster delivery, or lower freight costs than national distributors. They may also help small practices select compatible tube holders, needles, labels, specimen bags, and shipping materials. The disadvantage is that regional vendors may carry fewer brands and may have less reliable access during national shortages.
Group purchasing organizations can negotiate substantial contract discounts for hospitals and large healthcare systems. Reported savings vary by product category, volume, contract structure, and member participation. A negotiated price is not necessarily the lowest total cost if the organization must purchase large quantities, accept limited substitutions, or pay additional distribution fees.
How Much Do Red-Top Tubes Cost?
The price of red-top blood collection tubes varies considerably. Important factors include manufacturer, tube material, tube size, additive, sterility, packaging, order volume, contract status, and shipping destination. A small office may pay more per tube when purchasing a single box, while a hospital may obtain lower unit pricing through a multi-case contract.
In broad market terms, standard evacuated serum tubes are often priced from several cents to more than one dollar per tube, depending on the configuration and purchasing channel. Specialty tubes, low-volume tubes, glass tubes, sterile products, and individually packaged products can cost substantially more. Prices may also rise during supply shortages or when a buyer requires a particular brand with limited substitutes.
Published catalog pricing is not always the final price paid by a healthcare organization. Contract customers may receive discounts that are not visible in public listings. Conversely, a low catalog price may exclude handling, freight, fuel surcharges, or minimum-order fees.
For accurate comparison, purchasers should calculate total landed cost rather than unit price alone. A useful calculation includes the following:
-
Product price per tube or per case.
-
Freight, handling, and delivery fees.
-
Discounts, rebates, and contract credits.
-
Expected waste caused by expiration, damage, or incorrect ordering.
-
Administrative costs related to multiple vendors and invoices.
-
Costs associated with emergency purchases when routine inventory is unavailable.
Important Specifications to Compare
Tube Material
Red-top tubes may be made from glass or plastic. Glass tubes can be preferred for certain laboratory procedures, while plastic tubes are lighter and less likely to break during handling and transport. Plastic also reduces the risk of broken glass in phlebotomy areas and specimen-processing departments.
The laboratory should determine whether the intended test has a validated preference for glass, plastic, or a specific tube manufacturer. Material can affect clot formation, centrifugation, specimen stability, and compatibility with automated processing equipment.
Clot Activator
Plain red-top tubes and clot-activator tubes are not automatically interchangeable. A Clot Activator may shorten the time needed before centrifugation, which can improve Workflow in emergency departments and high-volume outpatient centers. However, some assays or laboratory procedures may require serum collected without an activator.
The buyer should confirm whether the tube is labeled as plain, serum, or serum separator and should review the additive information. If there is uncertainty, the laboratory supervisor, pathologist, or technical director should be consulted.
Draw Volume and Tube Size
Common tube sizes include approximately 2 milliliters, 3.5 milliliters, 5 milliliters, 7 milliliters, and 10 milliliters, although exact capacities vary by manufacturer. Smaller tubes can be valuable for pediatric patients, Geriatric Patients, Oncology Patients, and other individuals for whom blood conservation is important.
Tube dimensions also matter. A tube that fits one centrifuge rotor or automation line may not fit another. Purchasers should check the tube’s height, diameter, fill volume, cap design, and compatibility with racks and carriers.
Expiration Date and Shelf Life
Evacuated tubes have expiration dates because the vacuum may change over time and additives may lose performance. If the tube’s vacuum is reduced, the tube may not fill to the intended volume. This can create problems with blood-to-additive ratios, specimen volume, and laboratory processing.
Healthcare facilities should request adequate remaining shelf life at delivery. A large discount may not be beneficial if the facility cannot use the entire case before expiration. Inventory software or a first-expire, first-out system can reduce waste.
Regulatory and Quality Documentation
Clinical purchasers should confirm that the product is labeled for its intended use in the United States and that the supplier can provide relevant quality documentation. Depending on the product and organization, documentation may include certificates of analysis, lot information, manufacturer instructions, safety information, and regulatory status.
The U.S. Food and Drug Administration regulates medical devices, including many blood collection systems. The exact regulatory pathway depends on the product and intended use. Buyers should not assume that every tube listed in a laboratory catalog is cleared or suitable for diagnostic patient testing.
Why Tube Selection Affects Specimen Quality
Laboratory errors are often divided into pre-analytical, analytical, and post-analytical categories. The pre-analytical phase includes patient identification, tube selection, Venipuncture, filling, mixing, transport, processing, and storage. Various laboratory quality studies have found that pre-analytical issues account for a large majority of laboratory errors, with frequently cited estimates ranging from approximately pre-analytical errors. The exact percentage varies by study design, laboratory setting, and definition of error, but the purchasing decision clearly affects this phase.
Choosing the wrong red-top tube can contribute to several problems:
-
Insufficient serum volume for the requested test.
-
Delayed clot formation or incomplete clotting.
-
Hemolysis caused by unsuitable collection or handling conditions.
-
Specimen Rejection because the tube is not approved for the assay.
-
Incorrect results caused by additive interference or tube-material effects.
-
Processing delays when a tube does not work with the facility’s centrifuge or automation system.
For these reasons, procurement should involve phlebotomy leaders and laboratory personnel rather than relying exclusively on a purchasing department. A less expensive tube may create greater costs if it increases recollections, delays testing, or requires staff to change established procedures.
Supply Chain Considerations in the United States
The Covid-19 pandemic demonstrated how quickly medical supply chains can be disrupted. Blood collection tubes, swabs, personal protective equipment, and other consumables experienced demand surges, transportation delays, manufacturing interruptions, and allocation controls. Although market conditions have changed, healthcare organizations continue to treat critical collection supplies as strategic inventory items.
Large U.S. suppliers generally provide more robust distribution networks than small vendors, but no supplier is immune to shortages. A facility that depends on one brand should maintain an approved alternative when possible. However, substitutions should be evaluated and documented by the laboratory before they are introduced into routine testing.
Purchasing teams should monitor usage trends rather than ordering based only on historical averages. Emergency department volume, seasonal respiratory illness, new testing programs, staffing changes, and changes in outpatient services can alter tube consumption. A basic safety-stock calculation should consider average daily use, supplier lead time, demand variability, and the consequences of stockout.
Some hospitals maintain several weeks of critical phlebotomy inventory, while smaller offices may keep only a few weeks of supply because of limited storage space. The appropriate level depends on local demand and supplier reliability. Facilities should avoid excessive stockpiling when tubes have limited remaining shelf life or storage conditions are difficult to control.
Questions to Ask a Supplier
Before placing an order, the purchaser should request specific information from the supplier. A written quote is preferable to a general verbal description because it creates a record of the exact product being purchased.
-
What is the manufacturer’s name and catalog number?
-
Is the tube plain or does it contain Clot Activator?
-
What material is the tube made from?
-
What is the nominal draw volume?
-
What is the case quantity and inner-box quantity?
-
How much shelf life will remain when the product ships?
-
Is the product intended for clinical diagnostic use or research use only?
-
Is the tube compatible with the facility’s centrifuge, automation line, and specimen racks?
-
What are the current lead time and back-order policies?
-
What substitute products may be shipped if the selected product is unavailable?
-
Are freight charges, handling charges, or minimum-order fees applied?
-
Can the supplier provide lot traceability and recall notification?
Choosing Between Direct and Distributor Purchasing
Buying directly from a manufacturer may provide access to technical representatives, product training, lot information, and long-term supply agreements. Direct purchasing can make sense for large health systems with predictable demand and centralized laboratory operations.
Distributor purchasing is often more convenient for smaller organizations and facilities that need many types of supplies. A distributor can consolidate orders, simplify accounts payable, and provide access to several brands. Distributors may also offer local inventory and more flexible order quantities.
The best approach may be a dual-source strategy. A facility can designate one supplier as its primary source and another as an approved backup. This reduces dependence on a single warehouse or manufacturer while preserving standardization. Any backup product should be assessed before an urgent shortage occurs.
Practical Buying Recommendations
For a hospital or large laboratory, the purchasing process should begin with a product standardization review. The laboratory can identify every red-top tube currently in use, the assays associated with each product, the average monthly consumption, and the costs of rejected specimens or recollections. The organization can then determine whether one tube can meet most needs or whether separate plain and clot-activator products are necessary.
For a physician office or urgent care center, simplicity and reliable delivery may be the highest priorities. The practice should select a tube that is accepted by its reference laboratory and can be ordered consistently in manageable case quantities. Staff should be trained to recognize the tube and follow the laboratory’s instructions for inversion, clotting, centrifugation, and transport.
For Mobile Phlebotomy services, packaging and transport are especially important. The organization should consider tube durability, temperature exposure, specimen labeling, leak prevention, and the ability to transport samples safely from multiple collection locations. A low-priced tube is not a good choice if it increases breakage or causes specimens to arrive outside stability limits.
Final Assessment of U.S. Supplier Options
Organizations purchasing red-top blood collection tubes in the United States have several reliable options. BD and Greiner Bio-One are prominent manufacturers of evacuated blood collection systems. Cardinal Health, McKesson Medical-Surgical, and Medline are major distributors that can support broad healthcare procurement programs. Fisher Scientific, Avantor, VWR, and Thermo Fisher Scientific provide access to a wide range of clinical and laboratory products from multiple brands.
Regional distributors and specialty laboratory vendors may also be appropriate, particularly when a facility needs smaller quantities, local service, or a specialized tube. The correct supplier is not necessarily the one offering the lowest advertised price. Product compatibility, regulatory status, technical support, delivery reliability, remaining shelf life, and substitution policies are equally important.
The safest purchasing decision begins by identifying the exact tube required by the laboratory: plain or Clot Activator, glass or plastic, draw volume, cap design, intended test use, and compatibility with existing equipment. After those specifications are established, buyers can compare quotes from manufacturers and distributors on a true total-cost basis. By involving laboratory professionals in procurement and maintaining an approved backup source, U.S. healthcare organizations can reduce supply risk while protecting specimen quality and patient care.
