Blue top tube which contains citrate.
The correct color tube for a thrombin test is typically a light blue tube. This tube contains sodium citrate as an anticoagulant, which is needed for coagulation studies.
Blue test tubes are typically used for blood coagulation (BC) tests.
The color of the top tube for HgA1C blood test is lavender. This type of tube contains EDTA as an anticoagulant additive to prevent blood coagulation.
A laboratory test where venous blood is clotted in a test tube is called a serum clotting test. Once the blood sample clots, it is centrifuged to separate the liquid portion (serum) from the clot, which can then be used for various diagnostic tests.
A light blue-top tube containing sodium citrate is typically used for collecting blood samples for coagulation profiles. The sodium citrate helps prevent blood from clotting during the test by chelating calcium.
A test tube is a common laboratory tool used to hold and mix small quantities of substances during scientific experiments. Due to its versatility and practicality, test tubes have become a symbol often associated with scientific research and experimentation.
A light blue tube typically requires a 1.9 ratio of anticoagulant to blood. This tube is often used for coagulation studies.
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 lavender or pink top tube is typically used for a PT (prothrombin time) test. This is the color used for collecting samples for coagulation studies.
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.
The color of the tube that is most often used for hematology CBC tests are
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.
