Opinion

CIRILLO, President Judge Emeritus.

This is an appeal from a judgment of sentence entered in the Court of Common Pleas of Cameron County. We affirm in part and vacate in part.

Appellant Steven James Michuck was convicted of driving under the influence of alcohol, in violation of 75 Pa.C.S.A. § 3731(a)(5)(i) (driving while blood alcohol content (BAC) is above .10% within three hours after driving, operating or having actual physical control of the vehicle) and 75 Pa.C.S.A. § 3731(a)(1) (under the influence to a degree rendering one incapable of safe driving). The court sentenced Michuck to serve 48 hours to one year in Cameron County Jail, and to pay fines and costs. A post-sentence motion was filed and denied. This appeal followed. Michuck raises three issues for our review:

1. Whether the appellant’s constitutional rights to due process and equal protection were violated by the adoption and admission of the arbitrary standards as to the conversion factor used in determining appellant’s BAC which was the basis for his conviction?
2. Whether it was prejudicial error for the Court to allow juror number 19 to remain on the jury after objection from appellant’s counsel when the arresting police officer was directly in her chain of command?
3. Whether the verdict was against the weight of the evidence when the facts on the record demonstrate a palpable abuse of discretion by the trial judge in admitting the arbitrary testing standard?

In order to preclude confusion as to our discussion of the propriety of blood testing procedures in light of our decision to vacate the appellant’s conviction under section 3731(a)(5), we preface our discussion with a review of this *598 court’s decision in Commonwealth v. Kelley, 438 Pa.Super. 289, 652 A.2d 378 (1994). In Kelley, we stated:

There exists both statutory and case law authority ruling that blood alcohol content test results are admissible in section 3731(a)(1) cases. Specifically, it has been determined that
[I]n a § 3731(a)(1) prosecution, so long as the defendant’s blood alcohol level exceeds .05%, the Commonwealth may introduce evidence regarding that defendant’s blood alcohol level.

Kelley, 438 Pa.Super. at 295, 652 A.2d at 381 (quoting Commonwealth v. Kemble, 413 Pa.Super. 521, 526, 605 A.2d 1240, 1242 (1992)). See Commonwealth v. Gonzalez, 519 Pa. 116, 546 A.2d 26 (1988). (1994). See also 75 Pa.C.S.A. § 1547(d)(2), (3). 1 Where a defendant is charged with a violation of section 3731(a)(1), a .10% test result is “but one piece of evidence to be considered in deciding whether the person was under the influence.” Commonwealth v. Sloan, 414 Pa.Super. 400, 607 A.2d 285, 290 (1992).

In Commonwealth v. Bartolacci, 409 Pa.Super. 456, 598 A.2d 287 (1991), this court addressed the practice of testing blood serum, instead of whole blood, to determine blood alcohol content. To prove its case, the Commonwealth in Bartolacci presented evidence of the results of blood alcohol testing based on blood serum. Id. at 458-60, 598 A.2d at 288. Bartolacci was convicted of homicide by motor vehicle while *599 under the influence of alcohol. Id. On appeal, Bartolacei, like the appellant herein, challenged the accuracy of this procedure. Id.

The distinction between whole blood and blood serum is significant. “Serum is acquired after a whole blood sample is centrifuged,” 2 Id. at 458, 598 A.2d at 288, which separates the the blood cells and fibrin, the blood’s clotting agent, from the plasma — the clear liquid is the blood serum. 3 When blood serum is tested “the results will show a blood alcohol content which can range from between 10 to 20 percent higher than a test performed on whole blood.” Id. at 458-59, 598 A.2d at 288. The reason for this is because the denser components of whole blood, the fibrin and corpuscles, see footnote 2, supra, have been separated and removed from the whole blood, leaving the less dense serum upon which the alcohol level test is performed. The value of the blood alcohol content in the serum is then determined. Because the serum is less dense than whole blood, the weight per volume of the alcohol in the serum will be greater than the weight per volume in the whole blood. Thus, an appropriate conversion factor is required to ealulate the corresponding alcohol content in the original whole blood sample. The Bartolacei court opined that even though the statutes do not dictate what form of blood must be tested, the only way to convict a person under section 3731 is to present evidence of the amount of alcohol by weight in a person’s whole blood, not blood serum. Bartolacci, 409 Pa.Super. at 458-60, 598 A.2d at 288. The statutory alcohol content limit, .10%, refers to the alcohol content of whole blood, not blood serum. As such,

*600 [w]here a test is performed on blood serum rather than whole blood the fact finder must be informed of this and must be provided with evidence of the alcohol by weight in the defendant’s blood in order to properly sustain a conviction based upon a violation of § 3731. Evidence offered of a reading based upon a test of blood serum, without conversion, will not suffice.

Id. at 459, 598 A.2d at 288 (emphasis added).

The Bartolacci court determined, therefore, that because the jury was informed of the fact that the blood alcohol test was performed on the defendant’s blood serum and that this figure would be converted into a whole blood alcohol content, the jury was free to conclude that Bartolacci’s whole blood, alcohol content, at the time of the accident, exceeded the limit of .10%. Id.

Likewise, in the instant case, Michuck’s blood serum was tested. 4 The jury was informed of this fact. The blood serum test indicated a blood alcohol content of .1847%. The Commonwealth introduced into evidence the conversion factor of 1.18, which was used on Michuck’s blood serum in order to obtain his whole blood alcohol content. 5 The .1847% figure, then, was converted into a weight per volume relative to that of whole blood (.1847 divided by 1.18), yielding a test result of .15%,
