DNA Twin Test

DNA Twin Test – Conclusively Determine Twin Zygosity

The DNA Twin Test is the most reliable way to determine whether a set of twins are identical (monozygotic) or fraternal (dizygotic). 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 email and/or mail.

Do the test kits expire?
