Sodium citrate is the most common anticoagulant used for coagulation tests like prothrombin time (PT) and activated partial thromboplastin time (aPTT). It prevents blood from clotting by binding to calcium, allowing for accurate measurement of clotting time.

What the common anticoagulant used in the vacuum tube?

The most common anticoagulant used in vacuum tubes for blood collection is ethylenediaminetetraacetic acid (EDTA). It is effective in preserving blood samples by binding to calcium ions, preventing coagulation.


What color tube for coagulation profile?

Light blue is typically the color of the tube used for coagulation profiles. It contains sodium citrate as an anticoagulant to prevent blood from clotting during testing.


What color tube in phlebotomy is used for PTT blood test?

The light blue tube is typically used for PTT (Partial Thromboplastin Time) blood test in phlebotomy. It contains sodium citrate as an anticoagulant to prevent blood clotting for accurate testing of blood coagulation.


What color tube that requires a 1.9 ratio of anticoagulant to blood?

A light blue tube typically requires a 1.9 ratio of anticoagulant to blood. This tube is often used for coagulation studies.

A red tube with no anticoagulant is typically used for an AFP test.


What color tube is needed for Direct Combs RH test?

The Direct Combs RH test typically requires a lavender/purple top tube, which contains EDTA anticoagulant to prevent blood coagulation. This type of tube is used for collecting blood samples for hematology tests, including the Direct Coombs test.


What color is citrate tube in blood drawing?

A citrate tube used for blood drawing is usually light blue in color. This tube contains sodium citrate, which is an anticoagulant used for coagulation studies.


What color tube to use for an iron test?

A lavender/purple top tube (containing EDTA anticoagulant) is typically used for an iron test. This anticoagulant helps preserve the sample for accurate testing.


What color tube do you use for coagulation test?

Light Blue. The additive in these tubes is usually Na+ Citrate and there is a marking on the test tube to indicate the minimum fill. Blood must come at least up to the line or it will not be acceptable.


What is the effect of decrease calcium in coagulation?

It hinders it. EDTA, a commonly used anticoagulant, works by chelating calcium. This also has the consequence that large volumes of blood transfusions causes calcium deficiency.


What is the anticoagulant used in this type of blood test?

The anticoagulant commonly used for blood tests is ethylenediaminetetraacetic acid (EDTA). It helps prevent the blood sample from clotting by binding to calcium ions, which are necessary for the blood to form clots.


What tube do i use for a coagulation specimen?

You would typically use a light blue-top tube containing sodium citrate for coagulation testing. This type of tube is used to prevent blood from clotting by binding calcium ions, which are essential for the coagulation process. It is important to fill the tube to the proper fill line to maintain the correct blood-to-anticoagulant ratio.
