– It is recommended to give blood in the morning, on an empty stomach, from 8 to 11 hours.

– Shortly before taking blood, drink 1-2 glasses of ordinary still water, this will reduce the viscosity of the blood, and it will be easier to take a sufficient amount of biomaterial for research, in addition, it will reduce the likelihood of clots in the tube.

2. Therapeutic drugs.

– If you are taking any medications, you should consult your doctor about the advisability of performing the test during treatment and about the possibility of canceling the drug on the eve of the study.

– When you fill out the form, you must specify the phase of the menstrual cycle or gestational age – this ensures that reliable results of the study are obtained with the correct ranges of normal (reference) values.
