Definitions
- the present invention relates to a method for removing fibrinogen contained in serum or plasma, and a member for the method.
- Blood tests are widely used in clinical tests to diagnose diseases. Most blood tests are serum tests, and the serum required for the test is usually blood clots with different specific gravities, such as fibrin and blood cells, obtained by coagulating blood collected in a blood test container and then centrifuging. It is separated from the gel-like mass in which the components are mixed. Blood test containers are supplemented with coagulation-promoting components to coagulate blood, which used to be adsorbable inorganic substances, etc., or that enzymes such as thrombin and snake venom have recently been used. As a result, the coagulation time is shortened and the time required for obtaining test results is shortened, thereby improving convenience.
