Twins DNA Test

Twin zygosity testing is used to differentiate identical (the same DNA) and fraternal (different DNA) twins or multiplets (triplets, quadruplets, etc.). This test requires a DNA sample from at least two alleged twin siblings. It is a useful test to determine blood or organ compatibility. Our test only requires a simple cheek swab which can be collected with our easy to use, at-home, collection kit. Should you be unable to collect a swab from any of the parties involved, you may choose to submit an alternative forensic sample at an additional charge. All aspects of private DNA diagnostic tests are kept completely confidential.

If you would like to collect samples without waiting for the kit to arrive, visit our instruction page for cheek swabs and hair samples collection.


$199 (for 2 individuals, +$99 for each additional individual)

*Additional fees for alternative samples

*All prices are subject to HST for Canadian residents.

We always give you the option of password protecting your case!
