The TMP Presumptive Semen Test Kit is administered by first collecting a negative control by testing an unstained sample. Next, a sample of the suspected stain should be collected using either a piece of filter paper or a cotton-tipped swab. One drop of each of the TMP reagents is then applied to the collected sample. A positive presumptive result for the presence of semen is indicated if the sample turns a bright blue color within seconds.
Presumptive Semen Test Kit – TMP
This Kit is a reliable laboratory test for presumptively indicating the presence of semen (acid phosphatase) on a suspected stain. TMP tests are the best-suited method for testing suspected stains, as it is more sensitive to the presence of acid phosphatase than other presumptive tests.
