What color tube is used for coagulation?
A blue top tube used for coagulation testing should be drawn before any other tubes containing additives. This includes tubes containing other anticoagulants and/or plastic serum tubes containing clot activators. A serum tube that does not contain an additive can be collected before the blue top tube.
What colored top is used for coagulation test?
2. Blue Top – Tube contains Sodium Citrate. Most often used for coagulation studies.
What are coagulation tubes?
Vitrex Coagulation Tubes are used to collect venous blood for coagulation tests. Coagulation Tubes have a buffered sodium citrate solution of 0.109 mol/l (3.2%) or 0.129 mol/l (3.8%). Double Tube technology provides an excellent condition for the test of PT and APTT values.
What color tube has heparin?
Green-top tube: Contains sodium heparin or lithium heparin. Use: Heparinized whole blood or plasma. Send plasma in a plastic transport tube labeled “Plasma, Sodium Heparin” or “Plasma, Lithium Heparin.” Send whole blood in a green-top tube.
Is PTT for heparin or coumadin?
PTT is still being used to monitor standard heparin therapy. Warfarin (Coumadin ®) anticoagulation therapy—the PTT is not used to monitor warfarin therapy, but PTT may be prolonged by warfarin at high dose. Typically, the prothrombin time/international normalized ratio (PT/INR) is used to monitor warfarin therapy.
What color tube is PT INR?
Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate. Evacuated collection tubes must be filled to completion to ensure a proper blood-to-anticoagulant ratio.
What is a gray top tube?
A blood collection tube containing powdered sodium fluoride and/or potassium oxalate, which inhibits glycolysis; ‘gray tops’ are used for glucose tolerance testing because glycolysis in the red cells would cause false-low glucose, for measuring lactate—transported on ice—lactate tolerance.
What is the red test tube used for?
Red-top tube, glass This tube is a plain glass Vacutainer® containing no clot activators, anticoagulants, preservatives or separator material. These tubes can be used for Blood Bank tests.
Which tubes are anticoagulants?
Pink-top tube (EDTA) This tube contains EDTA as an anticoagulant. These tubes are preferred for blood bank tests. NOTE: After the tube has been filled with blood, immediately invert the tube 8-10 times to mix and ensure adequate anticoagulation of the specimen.

What does green top tube test for?
Green top tube with sodium or lithium heparin: used for plasma or whole blood determinations. EDTA tubes: includes Lavender top, Pink top (used for blood bank testing), Tan top (used for lead testing), and Royal Blue top with EDTA (used for trace metal whole blood or plasma determinations).
What is the black tube used for?
An evacuated blood collection tube with a black stopper indicating that it contains sodium citrate as anticoagulant; used for determination of the Westergren erythrocyte sedimentation rate.
What color tube do you use for coagulation test?
Coagulation Tube Collection. Specimens for coagulation should be collected in 3.2% Sodium Citrate light blue top tubes. Be careful to not only notice the volume of blood in each tube as described below, but the number of tubes that may be required for the suggested test (s). + Specimens should be kept as Whole Blood and at Room Temperature if

It contains 3.2% sodium citrate as its anticoagulant. Mixing the blood inside the tube a few times is also recommended to form the plasma.
