Why preparation is important

Proper preparation ensures that blood test results are as accurate as possible. Factors such as food intake, hydration and medication use can affect the results. By preparing properly, you help lab technicians and doctors get a clear picture of your health.

General preparation tips

2. Hydration: Drink plenty of water before the blood draw. Being well hydrated makes it easier to draw blood.

3. Medication Use: Take your medications as prescribed unless your doctor says otherwise. Some medications may affect test results, so always discuss this with your doctor.

4. Avoid alcohol and caffeine: Avoid alcohol and caffeine 24 hours before your blood test, as these substances can affect your blood levels.

Preparation for home finger prick sampling
