After blood collection, gently reverse the blood collection tube for 4 to 5 times, mix the sample, and wait for the sample to fully coagulate
It needs to be placed for 30min, the centrifugation radius is 8cm, and the centrifugation speed is maintained at 3500-4000r / min for 10min. Serum and blood
The clot is completely separated by the separating glue, and the serum sample can be directly detected on the machine or transferred to the matching test cup of the instrument. With this
Only under these conditions can high-quality serum samples be prepared, which shows that the separation of gel is effective. If the centrifugal speed is too low, it will affect the separation
The strength of the gel is relatively weak, the separation gel does not rotate well or the blood in it is centrifuged without complete coagulation, and fibrin condensate may appear
Staying in serum or colloidal layer may cause hemolysis. Except for emergency treatment, general biochemical examination is better to completely coagulate the blood
After fixation, the fruit was well preserved by centrifugation.
