<P> The Frye standard, Frye test, or general acceptance test is a test to determine the admissibility of scientific evidence . It provides that expert opinion based on a scientific technique is admissible only where the technique is generally accepted as reliable in the relevant scientific community . In Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579 (1994), the Supreme Court held that the Federal Rules of Evidence superseded Frye as the standard for admissibility of expert evidence in federal courts . Some states, however, still adhere to the Frye standard . </P> <P> This standard comes from Frye v. United States, 293 F. 1013 (D.C. Cir. 1923), a case discussing the admissibility of systolic blood pressure deception test as evidence . The Court in Frye held that expert testimony must be based on scientific methods that are sufficiently established and accepted . The court wrote: </P> <P> Just when a scientific principle or discovery crosses the line between the experimental and demonstrable stages is difficult to define . Somewhere in this twilight zone the evidential force of the principle must be recognized, and while the courts will go a long way in admitting experimental testimony deduced from a well - recognized scientific principle or discovery, the thing from which the deduction is made must be sufficiently established to have gained general acceptance in the particular field in which it belongs .
