DNA Cousin Test

If the parties to be tested live in different cities, we can split the kit for you and send the kit components to different addresses. Since the cousin test kit components are individually barcoded, the samples will still be tested together once they arrive at the laboratory. To order a split kit, simply enter the following information in the comments box of the order form when you check out.

“Please split this kit. Send one cousin’s portion of the kit to (Cousin’s name and shipping address), and send the other cousin’s portion of the kit to (Cousin’s name and shipping address).”

An extra shipping fee of $10 will be automatically applied for each additional address within the US. Split kits will be shipped out using USPS First Class Package Service.

The DNA cousin test not as powerful as a DNA paternity test so this test should only be considered in situations where it is absolutely impossible to test the alleged father using a DNA paternity test. The paternity test will always give an absolutely conclusive result regarding paternity. Whenever the alleged father is available for testing, the paternity test is always the recommended test as it is the most powerful and conclusive test. However, in cases where the alleged father is not available for testing and there is no other option but to test the cousins, the DNA cousin test can provide a statistical analysis of the probability of relationship.

When a DNA cousin test is performed, the autosomal STR profiles of the alleged cousins are obtained and compared. A statistical analysis is performed based on the match type typically expected for true biological cousins and a “Combined Kinship Index” value is obtained. The value is compared against the following chart:

Combined Kinship Indexes and their verbal equivalent:
Combined Kinship Index >10000 = Practically proven
Combined Kinship Index from >1000 to 10000 = Highly likely
Combined Kinship Index from >100 to 1000 = Very likely
Combined Kinship Index from >10 to 100 = Likely
Combined Kinship Index from >1 to 10 = Slightly more likely than unlikely
Combined Kinship Index of 1 = Inconclusive
Combined Kinship Index from 0.1 to <1 = Slightly more unlikely than likely
Combined Kinship Index from 0.01 to <0.1 = Unlikely
Combined Kinship Index <0.01 = Highly unlikely

The private DNA cousin test is for personal knowledge only. It is intended for families to find out the truth before deciding on the next step.
