Abstract

BENOZZI, Silvia Fabiana et al. Tomar mate previo a la flebotomía no interfiere en las pruebas bioquímicas de rutina. Acta bioquím. clín. latinoam. [online]. 2019, vol.53, n.4, pp.477-486. ISSN 0325-2957.

In the present study the effect of drinking mate in routine biochemical tests was evaluated. Blood was collected from 32 female volunteers after a 12 h fasting period. In addition, 1 hour (T1), 2 hours (T2), and 3 hours (T3) after drinking 5 mates, blood was collected again. Hematological parameters and clinical chemistry analytes were studied. The results were analyzed using statistical tests for related samples. Mean difference % (MD%) was calculated for each analyte and was further compared with reference change value (RCV). The MDs% higher than RCV were considered clinically significant. At T1, T2, and T3 the count neutrophils, eosinophils and lymphocytes were lower than at T0. Also glucose, urea, creatinine, and cystatin C values were lower than at T0 whereas total proteins, LDL-C, and LD enzymatic activity values were higher than at T0. In all cases, variability was statistically significant but not clinically significant. Drinking 5 mates prior to phlebotomy does not interfere with the results of routine biochemical tests.
