Opinion

Opinion by

Judge CRISWELL.

Defendant, James Banks, appeals from the judgment of conviction entered upon a jury verdict finding him guilty of first degree sexual assault. We affirm.

The victim, an apartment house manager, testified that the defendant came to her apartment to inquire about renting a unit. She asked him to return in a few days because she was ill and could not show any apartments at that time. The defendant came back the following week and entered the victim’s apartment to fill out a tenant application form. It was then that the sexual assault occurred.

I.

Defendant first contends that the trial court erred by refusing to conduct a pretrial hearing to determine whether the testimony of the prosecution’s expert in forensic serology was scientifically reliable. Defendant further asserts that additional error resulted when the expert’s testimony was admitted at trial. We disagree with both contentions.

In Frye v. United States, 293 F. 1013 (D.C.Cir.1923), the court held that expert testimony, to be admissible, must be based upon “a well-recognized scientific principle or discovery ... [which has] gained general acceptance in the particular field in which it belongs.” The Frye test has been adopted by the Colorado Supreme Court. People v. Anderson, 637 P.2d 354 (Colo.1981) (evidence of polygraph test inadmissible).

People v. Anderson, supra, was tried before the adoption of the Colorado Rules of Evidence. Since the adoption of those rules, the Colorado courts have refused to apply that test at least in those circumstances in which the testimony does not relate to “novel scientific devices and processes involving the manipulation of physical evidence.” People v. Hampton, 746 P.2d 947 (Colo.1987) (involving admissibility of rape trauma syndrome testimony). See People v. Campbell, 785 P.2d 153 (Colo.1989) (testimony as to reliability of eyewitness identifications).

While the Hampton court noted that some commentators have argued that the Frye test is “at odds” with Fed.R.Evid. 702, upon which CRE 702 is based, we do not read the court’s opinion as a blanket rejection of the Frye test in all cases. Indeed, this court has applied the Frye test to cases arising after the adoption of the rules. See E.M.F. v. N.N., 717 P.2d 961 (Colo.App.1985). Rather, the Hampton exception to Frye appears limited to cases in which the testimony at issue is not premised on some sort of physical testing. But see People v. Campbell, supra. We shall, therefore, assume, without deciding, that the Frye test must still be applied to determine the admissibility of the evidence offered here.

Under Frye, if the scientific evidence to be offered is of a type that has been admitted in other cases, a pre-trial Frye inquiry is necessary only if the opposing party makes a timely request for such inquiry, supporting such request by reference to authorities that indicate that there may not be general scientific acceptance of the principle employed. State v. Harris, 152 Ariz. 150, 730 P.2d 859 (App.1986).

The expert evidence at issue in this case described the results of a semen analysis test known as the “absorption inhibition” method. This type of test is often used to determine the blood type of an assailant from specimens of semen left by him. This is possible because most persons secrete antigens, which are indicative of blood types, into other body fluids, such as semen and saliva. If the testing of a defendant’s saliva reveals the presence of antigens with the same characteristics as those detected in the semen samples, then the conclusion may be drawn that defendant possesses the same blood characteristics as the assailant. See Annot., Admissibility in Prosecution for Sex Related Offense of Results of Tests on Semen or Seminal Fluids, 75 A.L.R. 4th 897 (1990); U.S. Department of Justice, Sourcebook in Foren *205 sic Immunology & Biochemistry § 19 (1983).

Many jurisdictions have recognized that the absorption inhibition test is generally relied upon by the scientific community to establish an individual’s blood type and have admitted the results of such testing for this purpose. See People v. McGee, 88 Ill.App.3d 447, 43 Ill.Dec. 641, 410 N.E.2d 641 (1980) (absorption inhibition test appears to be a procedure regularly undertaken to determine blood type); State v. Young, 668 S.W.2d 263 (Mo.App.1984) (absorption inhibition test is accepted as accurate and reliable by the scientific community); Annot., 74 A.L.R.4th 897, supra.

In this case, however, the expert testimony went beyond opining that the assailant and the defendant possessed a common blood type. In addition, the People’s expert testified that both the assailant and the defendant also fell within a narrower group known as “weak secretors.” It was this evidence which defendant asserted was unreliable.

Rather than conducting an initial Frye-type hearing, the trial court here required the People to make an offer of proof with regard to this aspect of the expert’s testimony. In doing so, the People referred to the Sourcebook in Forensic Serology, supra, which was also the only authority relied upon by defendant to suggest that the expert’s testimony was not based upon an accepted scientific principle.

After reviewing the Sourcebook and noting that the very procedures challenged by the defense as unreliable were referred to and explained therein, the trial court concluded that the tests were scientifically recognized in the community.

In light of the circumstances of this case, we are satisfied that the trial court’s reliance on the Sourcebook in admitting the evidence was a proper exercise of its discretion. We premise our holding on the fact that the absorption inhibition method has generally been recognized as based upon accepted scientific principles and that the courts have admitted such evidence in criminal cases. Moreover, the Sourcebook, which identifies and discusses the existence of “weak secretors,” was accepted as authoritative by defendant. Thus, although the testimony objected to involved a more specialized application of the absorption inhibition test than is generally presented, the Sourcebook, having been recognized as authoritative by both sides, served as a sufficient basis for its admission.
