Reasons for doing a twin zygosity test

To satisfy their curiosity both parents of twins and twins themselves might be inclined towards knowing whether they are fraternal or identical twins. However, knowing for medical/health reasons is also important. In the case of the need for blood transfusions or organ donation, identical twins can donate blood to each other and moreover make more suitable organ donors. The chances of an organ being rejected are far lower when identical twins donate organs to each other.

Twin DNA test sample collection
