DNA Sibling Test

Find out whether individuals are full siblings, half siblings, or not related.

This DNA Sibling Test (Private Home Kit) is an ideal way to determine the likelihood that individuals are full siblings, half siblings or not related, when the parent(s) in question are not available for testing. The mouth swab can be collected quickly and discreetly in the privacy of your own home and sent to our laboratory for analysis. You will receive your results by mail or email or both.

FAQ

What if the parties to be tested live in different cities, can you split the kit?

The collection components are individually barcoded and will be tested together once the samples arrive at the laboratory. To order a split kit, please write the following into the Order notes box of the online order form “Please split kit”. Please also indicate the name and address to send each component. For example, please state “send one Sibling’s portion to… (specify name and address)” and “send the other Sibling’s portion to… (specify name and address)”.
