DNA Testing for Twins

Twin siblings can either be ”identical” or ”fraternal”, and knowing whether twins are identical or not is often difficult. Only a DNA test for twins is able to provide an accurate confirmation of your twin status.

Appearance alone often is not a reliable method in determining twin type because identical twins do not always look exactly the same and fraternal twins can sometimes look very similar, leading to confusion about exactly what type of twins they are. Sometimes, twins grow up never knowing for sure whether they are identical.

Reasons for doing a twin zygosity DNA test

There are various reasons to do DNA twins testing. 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 transplantation since the involvement of an identical twin can help save the others life.
