Siblingship DNA Testing

Family relationship answers you can trust

DNA test identifies siblings

A siblingship test is used to determine the statistical probability that two individuals are related as siblings. Direct paternity and maternity DNA tests are always the best option to determine biological relationships. However, in instances where the alleged parents are unavailable for DNA testing, siblingship testing provides another option.

Siblingship results are reported in a different manner than paternity test results. Instead of 0% or 99% or greater probability that you would see with paternity results, siblingship results will indicate if the test participants are more or less likely to be related as siblings based on the genetic material exhibited by each person. The strength of the tests will vary and may not provide conclusive results.

After this experience, I will never use another lab for any test I can run through Alliance DNA. Your customer service is surprising and your turn-around was right on schedule. Thank you for caring about the customer.

I ran a maternity test for a child custody situation and was able to find a great collection location near me and get a completed result within the same week.
