Highly accurate DNA parental testing became available in the 1980s with the development of RFLP. In the 1990s, PCR, developed in 1983, became the standard method for DNA parental testing. A simpler, faster, and more accurate method of testing than RFLP, it has an exclusion rate of 99.99% or higher.
In general, state and federal courts have increasingly accepted DNA evidence as admissible. The first state appellate court decision to uphold the admission of DNA evidence was in 1988 (Andrews v. Florida, 533 So. 2d 841 [Fla. App.]), and the first major federal court decision to uphold its admission occurred in Jakobetz. By the mid-1990s, most states' courts admitted DNA test results into evidence.
