| acid phosphatase test for semen | A screening test for semen by determining acid phosphatase content; because seminal fluid contains high concentrations of acid phosphatase, while other body fluids and extraneous foreign materials have very low concentrations, high values of acid phosphatase on vaginal aspirate or lavage, or on wash fluid from stains, render positive identification of semen, even if the male is aspermic.

| Gomori's non-specific acid phosphatase stain | <technique> A method in which formalin-fixed frozen sections are incubated in a substrate containing sodium beta-glycerophosphate and lead nitrate at pH 5.0; the insoluble lead phosphate produced is treated with ammonium sulfide to give a black lead sulfide. (05 Mar 2000) |
| Gomori's non-specific alkaline phosphatase stain | <technique> A calcium-cobalt sulfide method using frozen sections or cold acetone-or formalin-fixed paraffin sections, plus sodium beta-glycerophosphate as a substrate at pH 9.0 to 9.5 with Mg++ as activator; calcium ions precipitate the liberated phosphate, cobalt salt replaces the calcium phosphate, and ammonium sulfide converts the product to a black cobalt sulfide.
