Twin determination is a genetic test to determine whether twins, triplets, etc… are identical (monozygotic) or fraternal (dizygotic). These results are intended for personal use only and are not accredited for legal purposes.
Upon payment (prices are inclusive of VAT) you will be sent a pack containing instructions and the required number of cheek swab kits to perform zygosity testing on your samples. The kit remains in date for 6 months and can be completed and returned at any time during that period.
In the highly unlikely case that we are unable to produce satisfactory results from the original samples, you will be given the choice to either receive a full refund or for us to repeat the test at no extra charge (until satisfactory results can be given).
If you have any problems with payment, wish to cancel this twin determination request, or have any other queries, please contact:
