Study Purpose
The purpose of this study was to determine the effect of the polyester gel in microtainer tubes on 47 clinical chemistry analytes in blood. Blood collected from patients and normal volunteers was distributed between tubes and centrifuged before analysis.
Summary of Findings:
LDH was 9% higher in specimens centrifuged in reaction tubes than in specimens centrifuged in microtainers containing polyester gel, but the authors report direct incubation of the serum with the polyester gel had no effect on LDH. Creatinine, phophatidylcholine, and alkaline phosphatase levels were significantly higher in specimens centrifuged in microtainers containing polyester gel than in reaction tubes, but the increase was not clinically relevant and the increase in phosphatidylcholine was only found in serum. The authors conclude that the polyester gel containing microtainers are suitable for all assays except measurement of LDH.
