DNA Testing for Twins

easyDNA offers DNA Twin Testing services to verify if twins are identical or non-identical. A DNA test for twins is able to scientifically confirm whether twins are identical or fraternal. The Twin test is offered at 199€.

Although appearance can sometimes give a clear indication of the relationship between twins, appearance alone is often not always a scientifically sound method for knowing whether twins are monozygotic twins (identical) or dizygotic twins (fraternal).

Reasons for doing a Twin Zygosity DNA Test

The most common reason is for curiosity purposes whereby parents of twins or the twins themselves may wish to know whether they are identical or non-identical.

However, other applications include medical requirements such as situations involving blood transfusions or organ transplantations. Identical twins who donate organs to eachother have a smaller chance of the organs being rejected. For additional information visit our article on Twin Zygosity Testing.
