Have found a stain on a bedsheet or garment that made you suspect cheating in your relationship? A semen screen test may help you find the answers you need.
IDTO DNA has more than 22 years of experience providing relationship DNA testing and forensic DNA testing services nationwide. Our team helps clients understand their testing options while maintaining confidentiality and professional handling of all submitted samples.
How to detect sperm on bed sheets?
Here are the most common methods for detecting sperm on bed sheets:
- Use a UV light in a darkened room: Keep in mind that other biological substances like saliva also fluoresce under UV light, so this method isn’t definitive on its own.
- Look for a yellowish stain: Dried sperm may leave a yellowish discoloration on the fabric, though this varies depending on the color of the sheets and is not conclusive proof on its own.
- Forensic Lab Testing: For the most conclusive results, a fabric sample can be sent to a forensic laboratory. DNA analysis can not only confirm the presence of sperm but also identify the individual it came from.
How much does a sperm detection kit cost?
Pricing starts for a sperm detection kit at $199.99. Below are our testing options.
This confidential test detects biological material containing DNA that is not consistent with the submitted reference samples (e.g., your own or your partner’s) on personal items such as clothing, bedding, or condoms. The analysis confirms the presence of semen but does not generate full DNA profiles or identify a specific individual.

Not sure which infidelity DNA test is right for your situation? Semen Screening is often the recommended starting point when the presence of biological material is unknown. Male/Female DNA Detection may be more appropriate when a stain or biological sample has already been identified. Use our DNA Sample Viability Checker to assess your sample before ordering.
DNA evidence that cannot fit inside the prepaid FedEx return envelope may require special shipping arrangements. Contact IDTO DNA at 888-204-0583 to discuss your evidence and determine the most appropriate testing and shipping option for your specific situation.
Frequently Asked Questions
Results are typically available within two to three business days after the laboratory receives all DNA samples. Once testing is complete, your results will be emailed to you, and a hard copy will also be mailed to your home.
Yes. Semen DNA testing is a reliable detection method. However, the laboratory’s ability to confirm the presence of semen on a submitted garment or personal item depends on the condition of the sample and how well it has been stored and preserved prior to submission.
No. Semen DNA Detection Testing results is informational analysis that does meet chain of custody establishment guidelines.
The length of time sperm may remain detectable on clothing or bed linens depends largely on the condition of the item and how it has been stored and preserved. Environmental exposure and improper storage can degrade biological material and DNA over time.
Common factors that may affect detection include:
- Exposure to direct sunlight
- Whether the item has been washed
- Contact with chemicals such as bleach
- The presence of moisture
- Storage conditions that may promote bacterial growth
In our experience assisting clients with semen detection testing, samples submitted for analysis have ranged from items only a few days old to items that were several months—and in some cases even a couple of years old. Whether detectable results can be produced depends largely on the environmental conditions and storage of the item prior to testing.
Upon completion of your semen detection test, you will receive a report summarizing the laboratory’s findings. The report will indicate either a positive result, meaning the presence of male semen was detected on the submitted item, or a negative result, meaning no male semen was detected.
Yes. IDTO DNA and its partner laboratory do not share any personal or genetic information with third-party companies. All information provided to our partner laboratory is kept secure and will only be released to third parties with the explicit consent of the participants involved or by court order. Specimen samples on file are kept for an average of 3 months, then destroyed
The primary difference between a semen screen strip test and a laboratory semen screen test using a garment is the level of analysis performed.
A semen screen strip test is an inexpensive, over-the-counter screening tool that can be purchased online or in some retail stores. The test provides a presumptive result within minutes and is designed to indicate whether semen may be present on a surface or garment. Because it is a screening test, the result is not considered a comprehensive laboratory analysis.
A laboratory semen screen test using a garment involves submitting the actual item, such as underwear, bedding, or clothing, to our partner laboratory for analysis. The laboratory analyzes the garment for the presence of semen and male DNA. Results are typically available within 2–3 business days after the laboratory receives the sample.
The accuracy of any laboratory analysis depends on the condition of the garment, the amount of biological material present, and how the item was stored before submission.
