Trennung von Plasma oder Serum von Vollblut

摘要

The method of the invention is for preparing a plasma or serum sample from whole blood and comprises mixing an aqueous solution of an inorganic salt or an amino acid or salt thereof with the whole blood in an amount of 20 % or less of the whole blood volume so that concentration of said inorganic salt or said amino acid or salt thereof becomes 10 to 200 mu mol/l ml whole blood, and then, filtering the whole blood to remove blood cell components. According to the method of the invention, plasma separation from whole blood can be achieved efficiently, and recovered volume of plasma can be increased. By selecting reagent, good plasma which has no deviation in component viewpoint, and which is possible to measure in the same level accuracy as a plasma obtained hy centrifuging, can be obtained through a simple filtration operation.
