The AABB has been developing standards and accrediting laboratories in the parentage testing field since 1984. The Standards for Relationship Testing Laboratories is revised on a 24-month schedule, with new editions becoming effective on January 1 of even-numbered years. The RT Standards contains requirements for laboratories performing parentage testing as well as more complex relationship testing in cases where the following criteria are met:
- the identity of the individuals being tested can be confirmed by the laboratory or through a legal chain of custody
- the sample collection is witnessed by a third party with no interest in the test outcome; and
- the individuals being tested have consented to the test (or a consent has been provided through a court order)
Work on the 10th edition of Standards for Relationship Testing Laboratories has been completed and the book is available for purchase. The 10th edition became effective on January 1, 2012.
