Many people wonder if it is ok to drink water before taking blood, or if other drinks are ok too. It turns out that it even makes sense. Find out how drinking and eating affects blood test results.
Experts indicate that before a blood test, you need to drink a small amount of water (1 glass). It turns out that boiled water is best, because mineral water can distort the test result if you determine the level of electrolytes. Drinking flavored water with added sugar is also not recommended, as this can affect your glucose results.
