DNA Testing for Twins

A DNA test for twins can help confirm if siblings are identical twins or not. Twins can in fact either be 'identical' or 'fraternal'. Sometimes, the only way to confirm this is through Twins DNA Testing. The cost of a twin DNA test is $179.  

Twin DNA Testing: Why do this Test?

Knowing whether twins are identical or fraternal (dizygotic twins) is often difficult. Appearance alone is often not a reliable method to confirm twin type because identical twins (monozygotic twins) do not always look exactly the same, and fraternal twins can sometimes look very similar.

Reasons for ordering a DNA Twin Test include personal/curiosity purposes, medical purposes (situations requiring blood transfusions and organ transplantation) or legal purposes (identification requirements).

Identical twins occur when one egg is fertilised by one sperm. Due to identical twins being produced from the same fertilised egg, their DNA profiles will be identical. Fraternal twins have a different DNA profile and are born when two eggs are fertilised by two independent sperms.
