serum separation procedure
Routine blood separation is a necessary step in clinical experiments, so we often see centrifuges used to separate blood in the blood testing department of hospitals. Most clinical tests do not test whole blood, but mainly use serum that has fibrinogen removed as the main test object. However, serum separation is not a simple matter. It requires a series of procedures to obtain effective serum samples to achieve experimental purposes.
1、 What is serum?
The essence of blood coagulation is that it contains fibrinogen, which can be transformed into insoluble fibrin, and then interwoven into a network, trapping a large number of blood cells to form gel like blood clots. Generally, after the collected blood sample tube is placed for about 1 hour, the clot after coagulation contracts and hardens, resulting in the extrusion of a clear yellow liquid called serum.

2、 Serum Separation Procedure
There are many methods for serum separation, so the procedures vary. There are generally two common methods:
