content which can range from between 10 to 20 percent higher than a test performed on whole blood. The reason for this is because the denser components of whole blood, the fibrin and corpuscles, 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 calculate the corresponding alcohol content in the original whole blood sample. Hutchins, at *6 (citations omitted). See Commonwealth v. Kohlie, 811 A.2d 1010, 1013 (Pa.Super.2002) (<HOLDING>). In the present case, Appellant argues the
holding that in order to convict a defendant of dui under subsection 3802b the commonwealth cannot rely on the blood serum analysis alone it must introduce evidence of alcohol by weight in terms of whole blood holding that the dissipation of alcohol from a persons blood stream constitutes a sufficient exigency to justify a warrantless blood draw holding blood testing for alcohol content a search holding that blood alcohol content almost 30 over the limit together with testimony of intoxication at the time of driving was sufficient to convict contrasting a case in which the blood alcohol content was just barely over the limit which was insufficient to convict holding that once the officer received the arrestees blood test results showing the arrestee had a blood alcohol level of 000 the officer had actual knowledge of the arrestees innocence of the dui charge  and had an affirmative duty to release him
