The present invention relates to a forensic test strip and method for the detection of semen. This strip is comprised of a paper element coated with reagents which react to the presence of acid phosphatase (AP), an enzyme found in semen, and is sandwiched between a clear plastic cover and an opaque plastic backing. This assembly is peeled apart, the paper element exposed to a source of semen, and the clear cover replaced. A positive test is characterized by a bright purple color, which easily can be seen through the clear cover. An adhesive backing is provided, which allows an investigator conveniently to affix the test strip directly to a notebook.
