Some States use a modified Frye test. California, for example, has established a three-pronged test:

  • The reliability of the method must be established, usually by expert testimony.
  • The witness furnishing such testimony must be properly qualified as an expert to give an opinion on the subject.
  • The proponent of the evidence must demonstrate that correct scientific procedures were used in the particular case. 16
