Why Choose The AlphaBiolabs Home Twin Test Kit

Twin DNA testing is used to establish whether multiple children (such as twins, triplets, quadruplets, etc.) from the same birth are genetically identical or not. Identical siblings are monozygotic. In other words, they were formed from a single fertilized egg that went on to split into separate embryos. Monozygotic twins have the same DNA.

It may have been unclear in utero as to whether multiple siblings were identical. This is because identical twins don’t always share the same placenta and sac: it all depends on when the egg splits. Siblings that are of different sexes are not identical.

Establishing whether siblings are twins can help assess the likelihood of conceiving twins again: there is an increased risk for women who have had non-identical twins. In addition, some diseases may affect monozygotic children so you could establish whether both/all children need testing for a particular condition. Another popular and novel use of a DNA twin profile is as a unique gift idea for multiple birth parents or their children, for information purposes only.
