Opinion

*602 OLSZEWSKI, J.

¶ 1 This is a consolidated appeal from a single trial stemming from two separate information forms. The facts are very similar. The first set of charges stemmed from September 13, 2000, when appellant was stopped by the police after they observed him driving in an erratic manner. The officer that approached appellant’s vehicle noticed the odor of alcohol about appellant, his eyes were bloodshot, and his speech was very slurred and hard to understand. Although his vehicle registration was sitting on the center console beside him, he was unable to produce it. He performed field sobriety tests poorly. The two officers on the scene, who had fourteen and eighteen years’ experience, reached the conclusion that appellant was incapable of safe driving that night. He was arrested and submitted to a blood test that read 0.039 percent weight per volume of alcohol and 0.16 milligrams per liter (“mg/L”) of morphine. This testing was done at Analytic Bio-Chemistries, Inc., (“ABC”) by Paul Madsen, a laboratory technician.

¶ 2 The second set of charges resulted on September 29, 2000, when appellant was stopped again after a police officer observed that he was driving erratically. When asked for his paperwork, the officer testified that appellant had a “glazed look on his face.” He was asked to step from his vehicle, and, while the two officers on the scene were conversing, he began the field sobriety tests — poorly—without them. When the officer administered the tests to him, he did not complete them successfully. This officer, with two years’ service and fifty traffic stops, also reached the conclusion that appellant was incapable of safe driving that night. Again, appellant was arrested and submitted to blood testing, which revealed 0.14 mg/L of morphine. This testing was also done at ABC, but this time by Dr. Siek, director of the laboratory. At a consolidated bench trial, the Commonwealth produced Dr. Siek as an expert in toxicology. He formed the opinion that a person with either .039 BAC and 0.16 mg/L morphine or 0.14 mg/L morphine in their blood would not be able to operate a motor vehicle safely.

¶3 Appellant was convicted in both cases of driving under the influence of alcohol and/or a controlled substance which rendered him incapable of safe driving, in violation of 75 Pa.C.S.A. § 3731, as well as related summary offenses. His sentence included, among other things, incarceration of between 30 days and 12 months, but he was granted immediate parole from the bench. This appeal followed.

¶ 4 Appellant has raised two issues. 1 First, he claims that the trial court *603 erred by admitting Dr. Siek’s testimony on the grounds that his results were not generally accepted in the field of toxicology. Second, he assigns error to the trial court for not excluding the first blood test result because a qualified person, as defined by the Pennsylvania Code, did not perform it.

I. “General Acceptance” of Expert Testimony

¶ 5 Appellant asks this Court to find that the trial judge erred by admitting Dr. Siek’s opinion testimony that appellant was incapable of safe driving on the nights in question because he did not reach it in a generally accepted manner. The applicable standard of review to this request is:

Absent a clear abuse of discretion or error of law, a trial court’s decisions regarding expert testimony will be upheld. When reviewing the court’s factual findings, we are limited to determining whether those findings “rest on legally competent and sufficient evidence.”

Thomas v. West Bend Co., 760 A.2d 1174, 1177-78 (Pa.Super.2000) (citations omitted).

¶ 6 In Pennsylvania, expert testimony must have “gained general acceptance in the particular field in which it belongs” to be admissible. Commonwealth v. Topa, 471 Pa. 223, 369 A.2d 1277, 1281 (1977) (quoting Frye v. United States, 293 F. 1013, 1014 (D.C.Cir.1923)). Since the “Frye test represents an attempt to measure the quality of scientific evidence prior to admission, .,. [Pennsylvania] courts have considered this to be necessary whenever science enters the courtroom, because ‘there is the danger that the trial judge or jury will ascribe a degree of certainty to the testimony of the expert ... which may not be deserved.’ ” Blum v. Merrell Dow Pharmaceuticals, Inc., 705 A.2d 1314, 1317 (Pa.Super.1997) (quoting Topa, 369 A.2d at 1281) (text altered and emphasis added) (omission in original). The question, then, is whether the trial judge abused her discretion when she decided that Dr. Siek’s opinion as to appellant’s ability to drive safely was reached in a generally accepted manner.

¶ 7 In her written opinion, the trial judge points to the evidence that she relied on to form her conclusion that- Dr. Siek’s method was generally accepted. At a pretrial Frye hearing, he testified that the scientific community has recognized that morphine would affect a person’s ability to operate a vehicle. N.T. Motions Practice, 7/11/01, at 189-90. He further testified that the therapeutic range of morphine is between 0.01 and 0.10 mg/L and that the likelihood of impairment increases as one exceeds that level. Id. at 186,193-94. He testified that he relied on published materials, and who they were written by. Id. at 191-93. Finally, he testified that, to reach his conclusion, he considered:

The results of the laboratory findings. The comparison to previous findings that we have had with respect to this particular drug. The case history. That actual actions of the individual.... In other words, again, it is matching the situation up to the laboratory test findings and does it fit and does it make sense to myself as a toxicologist.

Id. at 184-85. Dr. Lange, appellant’s own expert toxicologist, admitted that Dr. Siek’s methodology was generally accepted. Id. at 205. In our own review of the record, we note that Dr. Siek also stated *604 that other toxicologists testify as to someone’s capability to drive safely “all the time. And the ones that I have heard go about it the same way as I am going about it. I’ve talked to [other] individuals and this was the way they carry out the practice of toxicology.” Id. at 185.

¶ 8 In sum, there was ample “legally competent and sufficient evidence” to support the trial judge’s conclusion that Dr. Siek reached his opinion in a generally accepted manner. Therefore, it was no abuse of discretion for her to admit his testimony. 2 Further, Dr. Siek’s testimony was cumulative to the facts stated in the introduction to this opinion, which independently would support the verdict that appellant was not fit to drive a vehicle on either night. As such, any error would have been harmless.
