What determines the number of tests in parentage testing?
Current AABB standards state that the tests used shall exclude, on average, at least 95% of falsely accused men, regardless of tests used (serum proteins, RBC, HLA, and/or DNA). Contract requirements also affect the number of tests performed. Testing can exclude, on average, 99.7% of falsely accused men. Additional tests may be run if the probability of paternity is lower after initial testing or other factors indicate additional testing. The sending agency must inform the laboratory if any factors exist that might influence the amount of testing, such as related alleged fathers.
