Blood plasma has a density of approximately 1,025 kg/m 3 (1.025 g/ml). [8] Blood serum is blood plasma without clotting factors. [5] Plasmapheresis is a medical therapy that involves blood plasma extraction, treatment, and reintegration.
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.

About 55% of blood is blood plasma, a fluid that is the blood's liquid medium, which by itself is straw-yellow in color. The blood plasma volume totals of 2.7–3.0 liters (2.8–3.2 quarts) in an average human.
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.
[2] [3] The buffy coat is usually whitish in color, but is sometimes green if the blood sample contains large amounts of neutrophils, which are high in green-colored myeloperoxidase. Human blood after separation by centrifugation. Plasma (upper layer), buffy coat (middle, white-colored layer) and erythrocyte (red blood cell) layer (bottom) can ...
The gel in SST II tubes (which appears slightly less opaque) is supposed [weasel words] to have less effect on drug levels in serum. [citation needed] Blood samples should be allowed time to form a clot at room temperature for 30–60 min. [6]
