What a lab test can tell you

1. Is it semen? A yes or no answer.
2. Whose DNA is it? Male or female, and whether it is from one person or more.
3. Is it your partner’s? If you also send something of your partner’s, like a toothbrush or hair with the root, the lab can compare them.

A lab can’t name a stranger. Only police can search the DNA database. But a test can show that the DNA is not your partner’s, and for many people that is the answer they need.

Why go through us, not straight to a lab

• Discreet. Results come to us, not to a shared email or letterbox.
• The right test first. We start with the stain check and only go to DNA if it is positive, so you don’t pay for tests you don’t need.
• A sample that counts. We tell you how to collect and post it so it isn’t wasted.
• Plain answers. Lab reports are full of science words. We explain what it means for you.
• The next step. If the result raises more questions, we can find out who with surveillance or a background check.

How it works

1. Call or message us. Tell us what you found. We’ll suggest the right test.
2. The lab posts you a kit. You post the item straight to the lab. We never handle it.
3. Results come to us. We write you a clear report and talk you through your options.

Pricing

Pricing depends on which tests you need. Call or message us and we’ll give you the exact price before you start.

How to keep the sample useful

• Don’t wash it, and handle it as little as you can
• Let it dry, then put it in a paper bag or envelope, not plastic
• Keep it somewhere cool and dry until the kit arrives

Common questions

Can the test tell me who the other person is?

No. Only police can search the DNA database. The test can show if the DNA is male or female, if it is one person or more, and if it matches your partner.

What do I need for a comparison with my partner?

Something only your partner uses, like a toothbrush, a used cup, or hair pulled out with the root. We will tell you what works best.

Will my partner find out?

Not from us. The kit and the results are handled discreetly, and results come to us rather than to your home.

What if the result is positive?

We explain what it means and the options from there, such as surveillance to find out who your partner is seeing.
