COMPARISON OF SEMIQUANTITATIVE AND QUALITATIVE METHODS FOR THE DETERMINATION OF PROTEIN VALUES IN URINE

Abstract

The analysis of urine is of vital importance for the diagnosis and therapeutic monitoring in renal patients and since the introduction of multiple test strips, the urine test has become a sensitive and faster procedure. The objective of the investigation was the comparison of the methods Quantitative - Colorimetric of the Pirogalol Red and the semi-quantitative method of Reactive Strips to determine protein values in urine in patients of the Bolivian Japanese Gastroenterological Institute of the city of Sucre. The study population consisted of a total of 100 patients of both genders (56 women and 44 men). It was found that between Germanie, Multistix and Biotech there are no statistically significant differences in terms of red pyrogallol colorimetric quantitative method, instead with Mission, Teco and Dialab if there are statistically significant differences. Differences in sensitivity, specificity, positive predictive value, negative predictive value and t-Test were also obtained, highlighting the Germanie strip test with 80.28% sensitivity, 100% specificity, 100% positive predictive value and 67,44% negative predictive value, followed by Multistix and Biotech.
