The Semen Detection Test Strip gives instant results. A positive result turns the test strip bright purple. The semen detection test is a real evidence test, not a consumer toy. It is used in the field and in laboratories by forensic scientists. Unlike consumer tests sold online, there are no liquid chemicals to mix, allowing for failsafe results. You can optionally test several items with a single strip. To do so, cut the strip into pieces. Your order includes cotton swabs and nitrile gloves to use with the semen test Common Questions How old can the stain be? The stain can be several years old if it has not been washed or degraded by heat or conditions. What is the purpose of the swab? Use the swab to transfer the stain from the item onto the AP test strip or PSA solution. This allows the stain to be undisturbed and available to be retested. What if I want to do DNA tests? Store the stained item in a un-sealed container and allow to air dry. About the Semen Test This is a real evidence test, not a toy. It is used in the field and in laboratories by scientists.

Rub the stain for at least 15 seconds to transfer the suspect stain to the swab. Open the Test Strip Open the test strip. The thick strip may split into two thin strips. If so both pieces can be used separately to do a test. Apply the Swab to the Strip Place the moistened swab with the stain on the test strip. If the swab is dry you can moisten it lightly. Purple in 15 Seconds: Positive Semen will make the test turn purple in 15 seconds. Other body fluids may cause a reaction that takes longer than 15 seconds and is light in color.

Review: Appears to be a reliable test kit - I cut the test strip paper in half to test a sample from 1) controlled group known substance (dried semen) and 2) suspected yet unknown substance (which after the test I suspect was merely dried vaginal discharge). I placed a small amount of water on each sample, then scrubbed each one with a new swab (3 are included in the kit) to ensure the substance transferred. The known sample initially was light color but within seconds turned to the darker color seen indicating that the test strip had a reaction to the semen. The unknown substance was light color and didn't change color at all indicating no test strip reaction and therefore negative. Review: Worked perfectly. Thank you seller - I am so glad I bought this. Wish I had taken pictures but didn’t. I had a known sample, a sample where husband admitted that it probably was after lying about it for 4+ months and one I wasn’t sure about. Tested all 3. The known and the one he admitted too turned dark right away and the other did not. Least I know the most recent isn’t . Also I was able to cut it in pieces which was nice. ## Features - The Semen Detection Test Strip gives instant results. A positive result turns the test strip bright purple.

We have a 5 pack available elsewhere here if you need more. The strips are big enough to cut in half if you want to get dbl the tests. **Q: Does this work if the semen is a few days old?** A: Yes i tested on aprox 2 weeks old and tested positive **Q: so the instructions say bright purple.. any variation of purple? violet?** A: The color should be deep and fast. You can cut the test strip into 3 parts and do a practice test on one of the parts using a known positive sample. Then you can see for yourself the color. Again it should be deep purple and not pink and it should be fast, in 15 seconds. **Q: How old can stain be** A: The stain can be several years old if not degraded by heat or environment. Acid phosphatase, is the enzyme the test looks for and that does degrade over time due to heat, etc. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Appears to be a reliable test kit *by C***D on October 8, 2020* I cut the test strip paper in half to test a sample from 1) controlled group known substance (dried semen) and 2) suspected yet unknown substance (which after the test I suspect was merely dried vaginal discharge).

Thank you seller *by J***J on May 16, 2026* I am so glad I bought this. Wish I had taken pictures but didn’t. I had a known sample, a sample where husband admitted that it probably was after lying about it for 4+ months and one I wasn’t sure about. Tested all 3.

We always turn our pockets inside out, but never the jeans - odd, then minds start to race with one thought being that someone turned the jeans to smell the crouch!, Gross-right. That idea was followed by finding a whitish stain on the family room futon - a spot just large enough to be...well, we bought this semen test kit. No gloves were included. The test strip is sandwiched between two thin plastic sheets, one clear and one solid white. Had to guess that the clear side would be the one to put the sample on, so the white side would be the base. Pulled apart this packaging while holding the sample, which is moist and should not dry out, on the cotton swab in hand. The test strip pulls up sticking to the clear top plastic and not instead staying glued to the white base. You see the dilemma - hands full, one pulling, one with swab - which should not dry - pulling, test strip surface not glued down, NO Gloves AND a test strip that is a (no matter what you do) Do Not Touch!!! There is a second swab - for reasons that would led us to another story - this second swab is still in the small open plastic-foil type bag, as luck would have it, close at hand (pun, yes) grabbed the second swab with pinky of the hand without the first swab - which Still should not dry - while that hand held the white base side...confused...using this never moist swab, managed to hold down the strip onto the white base while continuing to pull the clear top plastic Finally off, then took the Hope-it-was-Still-Moist swab and swabbed the surface of the test strip. Four different instructions all from the manufacturer, including a video on their web site, a separate YouTube, step-by-step directions on their web site and on the package - all to some important degree different, yet all consistent on one point - Do Not Touch! And still Gloves were seen everywhere except enclosed in the kit. ## Frequently Bought Together - Crime Scene Semen Detection Test, Single Pack - HQRP 390 nM 51 LED Flashlight Blacklight for Hotel Room Inspection, Saliva Sperm Identification, Pet Urine Detection, Scorpion Hunting, Security Control, Leak Detection, etc. - Crime Scene Semen Detection Test - P30 Antigen, Includes Supplies and Directions to Perform A Single Test - Used in Forensic Science Labs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/11241251-crime-scene-semen-detection-test-single-pack](https://www.desertcart.at/products/11241251-crime-scene-semen-detection-test-single-pack) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-06-09*
