light blue
A light blue tube is typically used for a prothrombin time (PT) test.
The tube color typically used for a prothrombin time (PT) blood test is a light blue-top tube containing sodium citrate as an anticoagulant.
The prothrombin test specifically evaluates the presence of factors VIIa, V, and X, prothrombin, and fibrinogen.
The INR has basically replaced the prothrombin time, or PT.
A light blue-top tube containing sodium citrate is typically used for a prothrombin time (PT) test, which is used to assess blood clotting function.
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.
A light blue tube is typically used to draw blood for a prothrombin time (PT) test. This tube contains sodium citrate as the anticoagulant, which helps preserve the blood sample for accurate testing.
A light blue stopper tube is typically used to collect blood specimens for prothrombin time tests. The light blue stopper indicates the presence of sodium citrate as an anticoagulant, which is important for accurate testing of clotting factors.
The color top tube used for prothrombin time (PT) is typically light blue. This tube contains sodium citrate as an anticoagulant, which is necessary to prevent blood clotting during PT testing.
A red-top tube is typically used to test for herpes antibodies through a blood test. The blood sample is collected into the red-top tube, which does not contain any preservatives or anticoagulants. It is important to check with the specific laboratory or healthcare provider for their preferred collection tube.
The preferred tube for collecting blood for an A1C test is a lavender/purple top tube, which contains the anticoagulant EDTA. This tube is used to prevent blood from clotting during testing.
The test is also known as the pro time or PT test.
