title: [Influence of specimen withdrawal on the results of chemical analyses of blood, plasma and serum in patients with stable or centralized circulation (author's transl)].
abstract: The influence of circulatory conditions, point of blood withdrawal (arterial, central or peripheral venous) and the plasma-serum relation on 29 clinical chemical and hematological parameters were studied with 22 polytraumatized patients. The conditions studied significantly affect the results, and must be taken into consideration in evaluating the results and their comparison to reference values. This is especially important for the determination of the catalytic activities of creatine kinase, aspartate and alanine aminotransferases, and alkaline phosphatase in centralized-circulatory patients, for the total protein the electrophoretic fractions and analyses of blood gas as a function of the point of blood withdrawal, and for the total protein, gamma-globulins and potassium when plasma is analysed instead of serum.
