Preparation of serum cups for a lipids panel designed to test cholesterol levels in a patient's blood. Serum (/ ˈ s ɪər ə m /) is the fluid and solvent component of blood which does not play a role in clotting. [1] It may be defined as blood plasma without the clotting factors, or as blood with all cells and clotting factors removed.
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.
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.
Crystalloid or colloid solutions such as human serum albumin or plasma protein fraction, are preferable to FFP for volume replacement.
