About our Twins DNA Test
For just $119, including the test kit and all lab fees, our Twins DNA test - also known as a zygosity test - can help determine whether multiple children from the same birth (such as twins, triplets, quadruplets etc.) are genetically identical or not.
Identical siblings are known as monozygotic and will share the same DNA. This is because they were formed from a single fertilized egg that went on to split into separate embryos.
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 using a zygosity test can help assess the likelihood of conceiving twins again: there is an increased likelihood for women who have had non-identical twins.
Some diseases may also affect multiple monozygotic children so you could establish whether both/all children need testing for a particular condition.
A Twins DNA Test is or zygosity test is also a unique gift idea for multiple birth parents or their children, for information purposes only.
