First Stage of the Creatinine Standardization Program in the Province of Chaco. Clinical Laboratories Technologies and Procedures Survey
Abstract
Introduction: The Ministry of Public Health, la Fundación Renal del Nordeste Argentino (Renal Foundation of the Argentinean Northeast), el Colegio Bioquímico (Biochemical School), all the institutions of the Province of Chaco, and La Fundación Bioquímica Argentina (Argentinean Biochemical Foundation) began the development of a Plasmatic Creatinine Standardization Program (PCrSP). Objective: The objective is to present the results of the survey conducted in the Clinical Laboratories (CL). Methods: A survey was performed in 100% (n= 39) of the CL participating in the program; 22 (56%) of them belong to the public sector and were selected by complexity, monthly rate of creatinine determinations, and proximity to vulnerable populations, and 17 (44%) of them are private CL that agreed to participate. Results: The results were as follows: 1) Technology: automatic (44.8%), semi-automatic (37.9%), manual (17.2%); 2) Method: 5 (13.9%) used endpoint and 31 (86.1%) used kinetic method; 3 laboratories did not provide a response; 3) Calibrators: 18 (36.7%) used serum matrix, and 7 (17.9%) aqueous patterns, and no data was obtained from 14 (35.9%) labs; 4) The Homogeneous systems were verified for 5 (13.2%) labs, and for 33 (86.8%) of them systems were heterogeneous; 5) Temperature: 16 (43.2%) reacted at 25 ºC, and 19 (51.4%) at 37 ºC; 6) Internal Quality Controls (IQC) and External Quality Controls (EQC): 15 (48.3%) performed both, 6 (19.4%) performed neither, 10 (32.3%) performed either of them (IQC or EQC), where 51.7% of the participating laboratories had partial or absent controls. Conclusions: Considering the heterogeneity observed in both the tools and the determination conditions, new operating lines for standardization were defined.
