Twin DNA Testing (Fraternal & Identical)

dna testing for twins

What is a twin DNA test?

A Twin DNA Test aka Twin Zygosity Test is a DNA test to help determine if two siblings are either identical or fraternal. This testing option is normally performed for curiosity and/or peace of mind purposes. It is important to note, this test is commonly used if one twin needs an organ transplant in the future. Utilizing the other twin is an excellent option for a transplant.

Can this type of sibling test help to determine paternity?

A twin test is designed to identify if two siblings are fraternal or identical as stated earlier. This DNA test compares each sibling’s genetic profile to determine if there is an exact match. If the twins are identical then it is a clear indication that identical twins share the same biological father.
