Liebermann's test for steroids

Protein precipitation is another simple pretreatment technique. The protein content of human body fluids and tissues is considerable, from about 6% by weight in plasma to greater than 50% by weight in liver and other organs. Numerous reagents have been developed to precipitate protein; two that are commonly used in drug analysis are trichloroacetic acid (10-15% in water) and tungstic acid (10% sodium tungstate in water and used in conjunction with 3n sulfuric acid). Once proteins have been precipitated, separation of aqueous and solid protein must occur by filtration or centrifugation.
