What is Siblingship Testing?

A siblingship test is useful for determining if individuals are full brother/sisters, half brothers/sisters or unrelated.


The fee for this test is based on the number of individuals tested. Results are available 3-5 business days after receipt at the laboratory.

Who else should take this test?

Whenever the mother(s) is/are known, it is strongly recommended that they be included in the test. Including the mother(s) in the test can increase the results ten-fold, where you might see a probability of 98% instead of only 83%.
