An improved fluorometric method for measurement of plasma glutathione is introduced. 10% trich loroacetic acid and pH 8.3 phosphate buffer solution were used instead of 25% HPO3 and pH 8.0 phosphate buffer solution respectively and the method might be performed under room temperature. The repetition tests and recovery tests of the method were favorable giving a sensitivity of 25ng /ml and a linear standard curve to at least 2500ng/ml. Plasma glutathione determined by this method in 39 healthy blood donators showed a result of 15.125± 3, 38μmol/L and no any sexual difference. The method is sensitve, accurate and less expensive.
