Some blood test needs you to be fast 8 – 12 hours before the test but you can drink plenty of water 24 hours before your appointment. This will make the blood drawing process easier.   You have to avoid alcohol 1-2 days and strenuous exercise before the test as they can affect some test results.   On the day of appointment, you are advised to wear loose and comfortable clothing to allow easy access to both arms and hands. If you need assistance, you can always give us a call and we will explain to you.
