Evaluation of Stability of Serum on Different Storage Temperatures for Routine Chemistry Analytes

The stability of 21 routine biochemistry analytes was evaluated from the specimens which had been stored under three different temperature conditions for 30 days. Most of the 17 analytes showed significant change, however, the specimens under lower temperature showed more stability than those under higher temperature. Glucose, Albumin, ${\gamma}$-glutamyl transferase, HDL cholesterol analytes were stable over 30 days under $22^{\circ}C$, $4^{\circ}C$, and $-66^{\circ}C$ conditions. This study might be helpful in interpreting the results reflecting the rate of change when inadequate specimens are measured.
