[Fast and effective method of extracting and separating progesterone from blood plasma]

A qualitatively new method is proposed for extraction and separation of progesterone from blood plasms, substituting the imported reagent hexane for the homeoproduced diethyl ether and the separating technique via freezing. The technical changes proposed improve the percentage of extraction of progesterone in blood plasma from 80 per cent to 95 per cent, making the method more sensitive to low concentrations of blood plasma progesterone.
