Resumen
En este estudio se evaluó el efecto de tomar mate en las pruebas bioquímicas de rutina. Se extrajo sangre a 32 mujeres voluntarias luego de 12 horas de ayuno y a la hora (T1), dos horas (T2) y tres horas (T3) posteriores a la toma de 5 mates. Se estudiaron parámetros hematológicos y analitos de química clínica. Los resultados se analizaron empleando pruebas estadísticas para muestras relacionadas. Se calculó la diferencia porcentual media (DM%) de cada analito en cada hora respecto del valor basal y se comparó con el valor de referencia del cambio (VRC). Una DM% mayor que el VRC se consideró clínicamente significativa. En T1, T2 y T3 los recuentos de neutrófilos, eosinófilos y linfocitos fueron más bajos que en T0, también los niveles de glucosa, urea, creatinina y cistatina C fueron más bajos que en T0, mientras que los valores de proteínas totales, colesterol transportado por lipoproteínas de baja densidad y la actividad enzimática de lactato deshidrogenasa fueron más altos que en T0. En todos los casos los cambios fueron estadísticamente significativos, aunque no lo fueron desde el punto de vista clínico. Tomar 5 mates antes de la flebotomía no interfiere en los resultados de las pruebas bioquímicas de rutina.
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.
