Serum sample preparation requires about 30 minutes of waiting time before it can be centrifuged and then analyzed. [23] However, coagulation can be hastened down to a few minutes by adding thrombin or similar agents to the serum sample. [25] Compared to serum, 15–20% larger volume of plasma can be obtained from a blood sample of certain size.
Blood serum and blood plasma are similar, but serum does not contain any clotting factors such as fibrinogen, prothrombin, thromboplastin and many others. Serum includes all proteins not used in coagulation (clotting) and all the electrolytes, antibodies, antigens, hormones and any exogenous substances, such as drugs and microorganisms.
Fibrinogen from plasma samples will be seen in the beta gamma region. Fibrinogen, a beta-2 protein, is found in normal plasma but absent in normal serum. Occasionally, blood drawn from heparinized patients does not fully clot, resulting in a visible fibrinogen band between the beta and gamma globulins. [citation needed]
