Brother. Sister. Father.

Sibling DNA testing determines if two or more individuals have common parents and can be useful in some paternity testing cases. Half siblings share one parent; full siblings share two biological parents. Learn whether or not brothers and sisters share the same father with IDENTIGENE sibling DNA testing to evaluate the probability of a full or half sibling DNA relationship.

DNA Sibling Test $495
Includes 2 Possible Siblings (Full or Half) and their Biological Mother(s) (optional, but strongly recommended). Results in 5 business days from the time that samples arrive at the laboratory.

Legal & Immigration DNA Testing

A "Legal" siblingship test, or sibling DNA test for legal purposes, like legal paternity tests, require accurate test results as well as proof of identity for each person participating in the sibling DNA test. For legal cases, IDENTIGENE tracks your DNA samples from the time they are collected at one of our DNA collection sites until the time they arrive in our DNA paternity testing laboratory. Following this chain-of-custody procedure outlined in the accreditation guidelines offers proof of the sibling relationship (or non-relationship) as well as proof of identity to a judge, social worker, or other government official.

Fraternity test?

Sometimes referred to as "fraternity testing" DNA siblingship tests can be performed to determine if two individuals (brothers and sisters) share the same mother and/or father by testing as full siblings (have the same mother and father), half siblings (only share one parent, either a mother or a father), or un-related. Paternity Testing is the process of determining the biological father of a child.

siblingship test questions?

  • Q. What if the alleged father is not available?
