How do I collect the DNA samples?

Once you have received your kit, simply follow the instructions included to collect your samples.

Rub the swab gently and painlessly on the inside of the cheek to collect cheek cells. Enough swabs are provided to test two siblings and the biological mother, if available for testing.

If you would like to test three siblings, please select this option when placing your order, and additional swabs will be included in your kit (fees apply). 

Is a parent's sample required?

For the most conclusive result, we do ask that the biological mother also provides a cheek swab sample, if possible.

However, this is not essential, and we can still perform a sibling DNA test without the mother’s sample. 

Your test kit will contain enough cheek swabs to collect DNA from two siblings and the biological mother (if available).

When will I receive my kit?

Simply buy your test online now, and we’ll mail it out to you immediately.

Your test kit will be sent directly to your chosen address in discreet, plain packaging, for complete confidentiality.

Can kits be sent to two addresses?

What is peace of mind testing?

At AlphaBiolabs, we offer peace of mind testing with all our DNA testing kits.

As the name suggests, a peace of mind DNA test is for personal use only.  

The results of these tests can give you the answers you need, but they cannot be used for legal purposes or in court proceedings.

Peace of mind tests also allow you to collect your samples quickly and easily at home, without the need to use a more costly and time-consuming third-party to verify the DNA sample collection.

Our money-back guarantee

AlphaBiolabs guarantees that we will produce the most accurate results possible from your DNA test samples.

In the rare case that we cannot provide a result with the samples provided, we will either send a new kit and re-test at no cost to you, or offer a 100% no-hassle refund.
