Do you offer DNA testing to determine if a set of twins are identical or non-identical?

Sibling DNA testing is definitely possible and we do conduct quite a lot of this type of work. Essentially, we are asking if two individuals are related as full siblings, as half siblings or are not related at all. Twins are essentially a special type of sibling DNA test and we can certainly test the DNA of twins to determine if they are identical or non identical non-identical. However, please go to our sister service, Dad Check Silver which offers DNA tests for more complex needs, such as this. Please contact us on 0191 543 6434, e-mail sales@dadchecksilver.com.
