Description
Microtainer® Blood Collection Tube, NaFl/Na2EDTA, 400–600 µL
The Microtainer® Blood Collection Tube with sodium fluoride (NaF) and dipotassium ethylenediaminetetraacetic acid (Na2EDTA) is a small-volume, additive-containing tube designed for capillary blood collection and handling. With a 400–600 µL draw range, it supports pediatric, geriatric, and difficult-venipuncture workflows where minimizing blood volume is important. The tube is intended for the collection, transport, and processing of whole blood specimens for in vitro diagnostic (IVD) testing in accordance with laboratory policies and validated methods.
Na2EDTA functions as an anticoagulant by chelating calcium to help maintain whole blood integrity, while NaF is commonly used as a glycolysis inhibitor to help preserve glucose concentrations during the pre-analytical phase. Together, these additives support specimen stability for assays where glycolysis control and anticoagulation are required. As with all blood collection devices, performance depends on correct fill volume, proper mixing, timely transport, and adherence to the test manufacturer’s specimen requirements.
Key features
- Small-volume collection: 400–600 µL capacity supports micro-sampling needs.
- Dual additive formulation: NaFl/Na2EDTA for anticoagulated whole blood with glycolysis inhibition.
- Designed for capillary collection: Suitable for fingerstick or heelstick workflows when used with appropriate lancets and collection technique.
- Specimen handling support: Enables standardized collection and downstream processing in clinical laboratories.
- Traceable workflow: Compatible with common laboratory identification and accessioning practices (labeling per facility protocol).
Intended use and compatibility
This tube is used to collect capillary whole blood for laboratory testing where NaF/EDTA specimen type is specified. Laboratories should confirm assay requirements, including acceptable tube type, minimum volume, mixing instructions, and stability limits, before use. If plasma separation is required, follow validated centrifugation parameters and tube-handling guidance established by your laboratory and instrument manufacturer.
Recommended collection and handling
- Prepare the patient and collection site according to facility policy and standard precautions.
- Collect capillary blood using an approved technique and fill the tube within the specified 400–600 µL range.
- Immediately mix by gentle inversion as required by your laboratory procedure to ensure additive distribution; avoid vigorous shaking.
- Label the specimen at the point of collection and transport promptly under appropriate conditions.
- Process, store, and test within stability limits defined by the assay manufacturer and laboratory validation.

Quality and safety notes
Use only by trained personnel following institutional policies, applicable regulations, and standard precautions for bloodborne pathogens. Do not use tubes that are expired, damaged, or improperly stored. Underfilling or overfilling may affect additive-to-blood ratio and test results. Dispose of used devices and sharps in approved biohazard containers. For detailed instructions and applicable warnings, consult the manufacturer’s product labeling and your laboratory’s procedures.
