siblings testing

 A siblingship test is used to determine the statistical probability that two individuals are related as siblings. The standard sample types for Siblingship testing are buccal swabs or FTA (blood) cards. If these sample types are not available, other non-standard samples can be used. Additional fees will apply. 

 Direct paternity and maternity DNA tests are always the best option to determine biological relationships. In instances where the alleged parents are unavailable for DNA testing, siblingship testing is an option to consider. Siblingship results are reported in a slightly different manner than paternity test results. Siblingship results will provide a probability percentage of relatedness and indicate if the test participants are more or less likely to be related as siblings based on the genetic material exhibited by each person. It is HIGHLY recommended to include the mother(s) of the siblings when performing a siblingship test. The strength of the tests will vary and may not provide conclusive results, especially without the mother(s). Siblingship tests can be used for legal or informational purposes. A legally-binding test result can hold up in court and has no expiration date. An informational test is as accurate as a legally-binding test but the results cannot be used in a legal capacity such as child support or custody matters.   The National DNA Center's siblings test can be used for both legal and informational. 

A half sibling test is a test to determine if two individuals share one common parent.  Meaning if they share the same mother or the same father but not both.
