ABSTRACT

Introduction. The correct analysis in the interpretation of the results of any biological analyte is essential for the health of the patient and it is strongly linked to comparing those results with reference ranges that are in accordance with the population that is being analyzed on a daily basis. The objective of this study was to establish reference ranges in adults for glycemia, urea, creatinine, uric acid, total cholesterol and triglycerides in a clinical laboratory and compare the values obtained with those included in the inserts for the corresponding age group. Methodology. The population consisted of 561 apparently healthy adults of both sexes that attended Biomasterclin Laboratorio in Valencia, Venezuela, whose ages were 57.1±18.1 years. Results. The reference ranges obtained for glycemia were 63.0- 108.8 mg/dL, urea 17.7-54.9 mg/dL, creatinine 0.60-1.41 mg/dL, uric acid 0.89- 726 mg/dL, total cholesterol 78.5-251.1 mg/dL and triglycerides 39.5-176.0 mg/ dL. The reference ranges proposed by the commercial kits used for the determination of glycemia and creatinine could be transferred to the evaluated population, while the rest of the reference ranges could not. Conclusion. Due to the differences that occur between the reference ranges in commercial kits compared to those of the population of individuals who attend clinical laboratories, it is necessary to establish reference values in each clinical laboratory.
