1. Study Purpose

   The purpose of this study was to determine the effects of collection tube type, and storage on clinical chemistry and hematological parameters in serum from pediatric patients.

   Summary of Findings:

   Serum collected in Microtainer tubes was free of leukocyte and platelet contamination and had no visible hemolysis. No effect of collection tube type was found on cholesterol, triglycerides, alkaline phosphatase, aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase, creatine kinase, total protein, creatinine, sodium, potassium, chloride, calcium, thyroxine, billirubin, blood urea nitrogen or phosphorus levels. Sodium levels were lower in specimens collected in Microtainer tubes, but the difference was not clinically significant. There was no effect of storage in the Microtainer tube for up to 24 h on potassium and lactate dehydrogenase levels.
