Advisory Commission Comments [2001].
The Frye test no longer exists in Tennessee. In McDaniel v. CSX Transportation, Inc., 955 S.W.2d 257 (1997), the Tennessee Supreme Court listed five nonexclusive factors taken from the federal case of Daubert v. Merrell Dow Pharmaceuticals, 509 U.S. 579 (1993):
"(1) whether scientific evidence has been tested and the methodology with which it has been tested;
"(2) whether the evidence has been subjected to peer review or publication;
"(3) whether a potential rate of error is known;
"(4) whether, as formerly required by Frye, the evidence is generally accepted in the scientific community; and
"(5) whether the expert's research in the field has been conducted independent of litigation."
