  • You should wake up at least 1 hour before giving a blood sample.
  • The day before giving a blood sample, you can eat and drink as usual, but limit the intake of alcohol, coffee and fatty food.
  • Do not eat or drink 10–14 hours before giving a blood sample. If needed, you may drink one cup of pure unflavoured still water during this time.
  • In the morning before giving a blood sample, avoid:
    • physical and emotional stress,
    • taking medicines, if possible,
    • smoking.
  • Before giving a blood sample, you should sit peacefully for at least 15 minutes in order to stabilise your blood circulation.
  • During the procedure, your mouth must be empty – you must not eat, drink or chew gum.
