What tube do you use for heparin?
What tube do you use for heparin?
Green-top tube: Contains sodium heparin or lithium heparin. Use: Heparinized whole blood or plasma.
What are heparinized tubes?
VACUETTE® Blood Collection Tubes (Heparin) Heparin VACUETTE® heparin tubes are coated on the inside wall with spray-dried lithium, ammonium or sodium heparin and are used to determine analytes in clinical chemistry. The additive acts as an anticoagulant, and blocks the clotting cascade.
When would you use a heparin tube?
Green-top tube (sodium heparin): Tube contains sodium heparin as an anticoagulant. This tube is used for preparing heparinized plasma, whole blood, and bone marrow specimens. Note: Tube should be inverted several times immediately after blood collection to prevent coagulation.
What do the different Colours of Vacutainers mean?
Orange or Grey/ Yellow ‘Tiger’ Top: Orange or Grey/Yellow ‘Tiger’ top vacutainers are utilized for STAT serum testing. They contain Thrombin, a rapid clot activator. 3. Green: Green top vacutainers contains Sodium Heparin or Lithium Heparin that inactivate thrombin and thromboplastin.
Do you centrifuge EDTA tubes?
Plasma preparation Collect whole blood into commercially available anticoagulant-treated tubes e.g., EDTA-treated (lavender tops) or citrate-treated (light blue tops). Cells are removed from plasma by centrifugation for 10 minutes at 1,000–2,000 x g using a refrigerated centrifuge.
When do you use a BD Vacutainer heparin tube?

How is the heparin applied to the tube wall?
The green top heparin tubes contain either the lithium or sodium salt of the heparin anticoagulant. Lithium heparin should not be used for lithium determinations. How is the heparin applied to the tube wall?
How much sodium is in a heparin tube?
When the Sodium Heparin tubes are filled to the proper volume, the sodium results will only be 1 to 2 mmol/L higher.
