ABSTRACT:
A method of gamma glutamyltransferase (GGT) analysis is suitable for use with hemolyzed fluid or dried whole blood samples which avoids the need for protein precipitation or centrifugation of the sample. Analysis is by first mixing a fluid or dried whole blood sample with a phosphate buffered saline solution containing a non-ionic biological detergent. The mixture is then vigorously agitated for one hour at room temperature. The activity of the GGT is then determined by reacting the mixture with a GGT substrate. Color is developed by a diazo coupling reaction with the enzyme reaction product. The intensity of the color is then measured.
