FAQS on bd vacutainer k2 edta

Q: What is the primary use of BD Vacutainer K2 EDTA tubes?

A: BD Vacutainer K2 EDTA tubes are designed for blood collection to prevent clotting. They contain spray-coated K2 EDTA anticoagulant, ensuring sample integrity for hematology and molecular testing. These tubes are commonly used for CBC, blood typing, and DNA analysis.

Q: How much blood can a 10 mL EDTA Vacutainer tube hold?

A: A 10 mL EDTA Vacutainer tube typically holds up to 10 mL of blood. The fill volume is calibrated to ensure the correct blood-to-anticoagulant ratio. Overfilling or underfilling may compromise test accuracy.

Q: What distinguishes BD K2 EDTA tubes from other EDTA Vacutainer types?

A: BD K2 EDTA tubes use potassium ethylenediaminetetraacetic acid in spray-dried form, while alternatives like K3 EDTA use liquid anticoagulant. K2 EDTA minimizes dilution effects, improving precision for cell counts. Always verify the anticoagulant type for test compatibility.

Q: How should I mix blood in BD Vacutainer K2 EDTA tubes after collection?

A: Gently invert the tube 8–10 times immediately after collection to ensure proper mixing. Avoid vigorous shaking to prevent hemolysis. Follow manufacturer guidelines to maintain sample quality.

Q: Are BD Vacutainer K2 EDTA tubes suitable for long-term storage?

A: These tubes are ideal for short-term storage at room temperature (up to 6 hours). For longer storage, separate plasma within 2 hours and freeze it at -20°C or lower. Always adhere to lab-specific protocols for stability.
