The thrombin time (TT), also known as the thrombin clotting time (TCT), is a blood test that measures the time it takes for a clot to form in the plasma of a blood sample containing anticoagulant, after an excess of thrombin has been added. [1] It is used to diagnose blood coagulation disorders and to assess the effectiveness of fibrinolytic ...
Sodium polyanethol sulfonate (anticoagulant) and growth media for microorganisms: Usually drawn first for minimal risk of contamination. [1] Two bottles are typically collected in one blood draw; one for aerobic organisms and one for anaerobic organisms. [2] Blue ("light blue") Sodium citrate (weak calcium chelator/anticoagulant)
Blue ("light blue") Sodium citrate (weak calcium chelator/anticoagulant) Coagulation tests such as prothrombin time (PT) and partial thromboplastin time (PTT) and thrombin time (TT). Tube must be filled to the proper line. Plain red No additive: Serum: Total complement activity, cryoglobulins: Gold (sometimes red and grey "tiger top" [10])
International normalized ratio (INR) which is a derivative of prothrombin time is a measurement of blood coagulation in the circulatory system. Both are used to determine the clotting rate of blood, which can be affected by anticoagulant usage, liver damage and Vitamin K levels. The preferred range of INR levels for a patient on anticoagulation ...
From outside New England were Manhattan Silver Plate in Lyons, New York; and Standard Silver Company, Ltd. in Toronto, Ontario, Canada. [3] [2] Into the 20th century, many silver designs carry either the International Silver Company brand, or the pre-existing brand continues, or both are listed as the design maker.
These tubes should be used with care when measuring drug or hormone levels because the drug or hormone may diffuse from the serum into the gel, causing a reduction in measured level.

For example, a blue-top tube is a 5 ml test tube containing sodium citrate as an anticoagulant, used to collect blood for coagulation and glucose-6-phosphate dehydrogenase testing. [5] Small vials used in medicine may have a snap-top (also called a hinge cap) molded as part of the vial.
