DNA Testing - Siblings

Sibling DNA Testing

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.

Legal DNA Tests vs. Informational DNA Tests

Which One Do I Need?

Legal DNA Tests

A Legal DNA Test is required when the results will be used in any legal process. A legal test requires that several procedures and documentation are safeguarded, therefore, the test is performed at an approved collection site on the person(s) to be tested since the chain of custody for a sample must be maintained throughout the process. A witness who is not part of the family must be present when the DNA is collected.

Legal DNA Tests should be used for:

  • Child support or custody cases
  • Visitation rights
  • Medical, military, or social security benefits
  • Adding or removing a name from a birth certificate
  • Adoption cases
  • Inheritance cases (biological relationship with the person who has died)

Informational DNA Tests*

Informational DNA Tests are performed for informational or “Peace of Mind” purposes, and therefore do not carry the strict requirements of Legal DNA tests. The sample can be collected by anybody, and they can be anonymous if they want to. For Informational DNA Testing, a kit will be sent directly to you, and the test can be be performed in your home and sent back to the lab. Of course, the results cannot be used in legal cases.

If you don't need results for legal reasons like child support or custody, the advantages of an Information DNA Test are:

  • Get answers FAST!
  • You can order an at-home DNA paternity test kit directly from ReliaLab Test.
  • You can collect your DNA in the comfort of your own home with a simple cheek swab.

* - Informational DNA Test can not be administered in the State of New York. All DNA tests in the State of New York must be legal DNA tests.
