Stability of analytes related to clinical chemistry and bone metabolism in blood specimens after delayed processing.

Abstract：

OBJECTIVES:We investigated the stability of 36 analytes related to clinical chemistry in a controlled storage study. DESIGN AND METHODS:Blood was collected from 11 subjects and was maintained for 45 min, 2.5 h, 5 h, or 24 h after phlebotomy before centrifugation. RESULTS:Statistically significant changes were observed only for parathyroid hormone, osteocalcin, zinc, pyridoxal 5'-phosphate, and homocysteine. CONCLUSIONS:These studies indicate that many analytes in clinical chemistry are stable for 24 h before centrifugation.

  • Circulating miRNA as fine regulators of the physiological responses to physical activity: Pre-analytical warnings for a novel class of biomarkers.

    abstract：:MicroRNAs are endogenous non-coding RNAs that post-transcriptionally regulate gene expression by specifically binding the target mRNA and by consequently inducing its degradation. miRNAs can be released into the circulation where they remain stable and they can be measured. Their changes reflect individual biologic ad...
