Acid Phosphatase is an enzyme secreted by the prostate gland that is present in large amounts in seminal fluid. It is not unique to the prostate and can be found in other biological fluids including vaginal secretions. It is therefore considered a presumptive chemical test for the presence of semen and semen must be confirmed by other means (sperm detection, PSA or DNA extraction).

WARNING – IF YOUR TEST IS POSITIVE USING THIS KIT, PLEASE CONFIRM WITH PSA OR DNA

Any AP test (home or laboratory) can produce false positive and negative results.
