The tube contains an anticoagulant. The acceptable anticoagulant is the concentration of sodium citrate 3.2%. The tubes must be filled to within 90% of the full collection volume. The tube should be then inverted a few times, gently and as soon as possible, for proper mixing with the anticoagulant. The total time between sample collection and testing should not exceed 24 hours.

International normalized ratio (INR) is the preferred test of choice for patients taking vitamin K antagonists (VKA). It can also be used to assess the risk of bleeding or the coagulation status of the patients. Patients taking oral anticoagulants are required to monitor INR to adjust the VKA doses because these vary between patients.

A normal INR is 1.0. Each increase of 0.1 means the blood is slightly thinner (it takes longer to clot). INR is related to the prothrombin time (PT). If there is serious liver disease and cirrhosis, the liver may not produce the proper amount of proteins and then the blood is not able to clot as it should. When your provider is evaluating the function of your liver, a high INR usually means that the liver is not working as well as it could because it is not making the blood clot normally.
