A Sibling DNA 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. Those who are united with long lost family members who could be brothers or sisters find this type of testing useful.
Full siblings, half siblings, or not siblings at all use DNA testing to discover the possibilities.
