Did you know that for 70% of same sex twins, an examination of the placenta and foetal membranes at birth will not yield conclusive information about whether they are identical or not? This is because twins can implant so closely together in the womb that their placentas fuse, giving the appearance of a single placenta.*
DNA testing accurately confirms if twins are identical or fraternal (non-identical). Identical twins will exhibit the same DNA profile, while fraternal twins will have different DNA profiles.
Samples are easily collected by you in your own home. The results of twin/triplet testing cannot be used for legal purposes, and are simply for your information.
This Twin/Triplet kit contains testing for two ($200) or three ($300) people.
