Intake Mate Prior To Phlebotomy Does Not Interfere In The Test Parameters

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 (T-1), 2 hours (T-2), and 3 hours (T-3) 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 Mos% higher than RCV were considered clinically significant. At T-1 , T-2 , and T-3 the count neutrophils, eosinophils and lymphocytes were lower than at T-0. Also glucose, urea, creatinine, and cystatin C values were lower than at T-0 whereas total proteins, LDL-C, and LD enzymatic activity values were higher than at T-0. 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
