Abstract

ACOSTA GARCIA, Edgar José; PENATE, Eloina  and  CRUCES, María Elena. Performance analysis of clinical laboratory in glucose and creatinine determinations. Acta bioquím. clín. latinoam. [online]. 2017, vol.51, n.1, pp. 107-113. ISSN 1851-6114.

External Quality Assessment Schemes (EQAS) of clinical laboratories (CL) are indispensable to compare performance in one or more analyte determinations among different laboratories. Performance of CL in Carabobo state for the determination of serum glucose and creatinine was evaluated. The study was not experimental, descriptive and cross-sectional field. A total of 22 public and private laboratories in Carabobo state were evaluated. Each CL was distributed 5 control sera (CS) level I (LI) and 5 level II (LII) for glucose and creatinine. Intra- and inter-laboratory precision, bias and total error of the results were evaluated. There was no CL competition for determining glucose and creatinine both levels tested. Only 3 (13.3%) CL were proficient in the determination of creatinine in the LI and LII. It can be concluded that the results obtained in CS glucose and creatinine may not be transferable between different CL, so it is important to implement quality control programs within laboratories or improve the existing ones to eliminate systematic errors and reduce randomization; besides, participation in EQAS is also necessary to determine the universalization of the CL results.
