Fasting and blood biochemical parameters

This is prospective study to evaluate the influence of the long-term fasting on the biochemical constants and deducing from it the credibility of the analyses carried out during this month. At thirty one healthy volonteers, three blood analysis was done per day at three different times: 9h of the morning, midday and 16h. Several biological parameters - glucose, cholesterol total, triglycerides, rates of protids, urea, creatinin, uric acid were made by system Synchron cx delta. We found that the concentration of some parameters does not accept any significant change during the day [triglycerides, urea], others accept a significant change only at the end of the day [glycemia, cholesterol], whereas the concentration in protids, uric acid and creatinin changes at a significant degree along the day. Observing Ramadan led to a change of several blood parameters, represents primarily increase in cholesterol HDL and a reduction in the glycemia. These changes do not affect the biological analysis done during the month of Ramadan if we respects the hour of fasting necessary before each measurement
