From Adelaide, South Australia:

Does dehydration make the reading of a blood sugar level finger prick test wrong? If the elderly person during summer does not drink enough, for example, and I test their blood sugar level?


The blood sugar level should be fine as long as the hematocrit (percentage of red blood cells in the fluid of the blood) is not higher than the recommendations of the individual meter. Needless to say it is important to keep up with fluids to prevent dehydration in the hot summer.
