Important – how to prepare for blood collection at Victoria Clinic
We should come on an empty stomach for blood donation. This ensures a sufficiently long fasting time necessary to obtain correct results. If it is not enough, they may change: protein, bilirubin, AST, ALAT, ALP and LDH, lipid parameters, glucose, creatinine, urea, sodium, and even leukocyte counts. On the day of the test we should also refrain from drinking coffee, even black, no additions. It affects hormonal balance, glucose and bile acid levels. It can also falsify bilirubin and lower cholesterol. In addition, coffee flushes out magnesium, thus affecting its serum concentration. Instead of coffee, it is good to drink some clean water in the morning. Another substance that should not be consumed a few days before the test is alcohol.
