Infidelity Test Questions You May Have

Which Infidelity test do I need?

The Semen Detection, Saliva Detection, and Blood Detection Infidelity tests are positive/negative tests.  They will tell you if the substance is present on your sample.  And, this may be all you need to know to answer your questions.  However, if you are a man wanting to know if the semen is yours, or a woman wanting to know a stain contains another woman's DNA, you'll need to do a DNA Comparison test and submit a sample of your DNA as a cheek swab.
 

If you only want to know if male, female, or a mixture of DNA is present on your sample–you want the DNA Detection Test.

If you are still not sure which one of the infidelity tests you need, call us at 800-908-9117 or send us a  and we'll assist you in selecting the appropriate test for you needs.

If you think there is a chance you have left your DNA on the sample by handling the area to be tested with your bare hands, we recommend you order the DNA Comparison Test and send a cheek swab from yourself.  This will eliminate you as a contributor to any DNA that may be found.

 

What can I send to be tested for proof of infidelity?

We can test almost anything for signs of infidelity: clothing – sheets – towels – sanitary pads – tampons – tissues – sex toys – condoms.  If you have something you want tested with one of our DNA infidelity tests but aren't sure about sending it check out the list below, or call us at 800-908-9117.  Have you found a stain on furniture, a car seat, or an item that would be missed?  If you have a suspicious stain you would like tested but can't send the item, you can send a swab of the area instead.  The instructions are here.

If you want to send an item for Infidelity DNA testing please note:

Items with a 90% or higher success rate of obtaining DNA:  Fresh semen on swab or fabric (if no vasectomy), mucus/sputum on tissue, napkin, etc, toothbrush

Items with a 60-90% success rate:  blood stain on fabric, tissue, gauze, etc., saliva stain, fingernail clippings (5-10 clippings), diabetic test strips (multiple strips recommended), ear swabs, cigarette butts (multiple preferred), tampon/feminine pad, drinking straw, dental floss

Items with 60% or less success rate:  hair (roots must be visible, 7-10 hairs needed), razor, comb/brush, chewing tobacco (less than three days old), jewelry, chewing gum (sugarless preferred), soda can/drinking glass, clothing (hats, bandannas, clothing worn next to skin) envelope flaps/stamps, condom

 

Will a vasectomy affect the test?

A vasectomy will not affect the ability to perform a semen detection test.  Our test looks for a protein that is present whether or not a man has had a vasectomy.  It can, however, affect the DNA infidelity tests.   DNA is present in highest concentrations in the sperm cells, so an absence of sperm can mean that no DNA will be detected.  DNA can also be found in skin, blood, or tissue cells that might be in the semen.  So while detecting DNA in semen from a vasectomized male is unlikely, it's not impossible.

Can I do a semen detection, then a DNA infidelity test if the semen test is positive?

Sure.  If you want to wait and get the semen detection test results first, then decide if you want or need one of the DNA infidelity tests, that's OK.  All the infidelity test samples are kept for 60 days after the results are issued, so you have time to decide if you want further testing, or if you have all the answers you need.  If you decide you want one of the DNA infidelity tests after you get your results, you will be given a discount code for $25 off any DNA Detection or DNA Comparison test--just contact us and we'll walk you through the process.

How old can a sample be?

A woman can discharge fluids from sexual activity for 5-7 days. How long you can detect any semen in the discharge depends on how the item has been stored. For semen detection testing, as long as the item hasn’t been laundered and the stain is still visible it can be testable for years.

DNA can also last for years as long as the item has been kept dry, and stored in a cool, dark place away from heat and direct sunlight.  Never store samples for infidelity tests in a plastic bag.  Plastic traps heat and moisture which can degrade the DNA making it more difficult to get a complete DNA profile.

Can I get my sample back?

Sure.  Just add the sample return to your order at checkout.  You only need to add it once no matter how many samples you have.  If you want to wait and get your test results first, that's OK.  All samples for infidelity tests are kept for 60 days after the results are issued if you don't add the return to your initial order.  You can decide you want the sample returned or if you want further DNA or other testing at any time during that period.  Just contact us and we'll help you arrange it.  All returns are processed on the 1st and 15th of the month.

Can My Results Be Used in Court?

Chain of custody refers to the paperwork trail documenting the way a sample is collected and handled throughout the entire infidelity testing process. Since you will be collecting the samples yourself and submitting them privately, you will not have a strict chain of custody and the test results you receive will be noted as "informational only". Strictly speaking, for results to have a strict chain of custody, the samples must be collected by an unrelated third party such as a hospital, clinic, ME’s office, funeral director, law enforcement, etc. For obvious reasons this rigorous identification and handling procedure is not always going to be possible with infidelity testing.  Courts and legal official know this, and the weight an agency will give the results is up to the agency.

What Our Customers Say

I didn’t know anything about infidelity tests until I called and talked to you guys.  Now my mind is at ease knowing my wife isn’t cheating on me and I can get through my day without constant worry.  Thanks!

Luis G

My boyfriend kept accusing me of cheating when I wasn’t.  I finally sent in a pair of my own underwear to prove to him that I hadn’t been with another man.  It was a far stretch to go, but now he believes me when I tell him he’s the only one.
