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.
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.
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.
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.
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.

A Partial Thromboplastin Time (PTT) test primarily assesses the efficacy of the intrinsic and common coagulation pathways, and it is commonly used to monitor patients on anticoagulant therapy with unfractionated heparin. Heparin acts by enhancing the activity of antithrombin III, which inhibits thrombin and factor Xa, thereby preventing blood clot formation. The PTT can also be affected by other anticoagulants like direct thrombin inhibitors or factor Xa inhibitors, but heparin is the most commonly associated anticoagulant with this test.
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.
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.
A blue tube is typically used for coagulation tests, most commonly for prothrombin time (PT) and activated partial thromboplastin time (aPTT). These tests assess the blood's ability to clot and are crucial for monitoring patients on anticoagulant therapy or for diagnosing bleeding disorders. The blue tube usually contains sodium citrate as an anticoagulant, which helps preserve the sample for accurate testing.
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.
A lavender/purple top tube (containing EDTA anticoagulant) is typically used for an iron test. This anticoagulant helps preserve the sample for accurate testing.
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.
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.
