Blood tests

If you want to have your blood tested, you have to discuss it with a doctor first. The doctor will decide what tests need to be carried out. You can then be booked by our nurse for a test on Monday, Wednesday or Friday. Blood is taken usually from 6.45am till 7.45 am in our surgery. If you want to have your blood taken somewhere else (e.g. at a laboratory), it’s no problem. But you would have to pick up the results there (or some laboratories can send it by post).

You must not eat for 12 hours before the blood test. Your supper on the night before should be light, without too much fat. You should not drink alcohol the night before. In the morning you can drink some water or tea, but without milk or sugar. Breakfast is not allowed. Exercise before the test is not recommended either. On the day of the test you are advised to come 5 minutes early and rest in the waiting room.

During the blood test you can sit or lie, as you wish. The blood is taken from a cubital vein or if this is impossible, from the vein in the back of the hand.

If there are some special parameters to be checked, which require a special regime, the doctor should inform you about what you need to do to prepare. For example, if you are taking thyroxin replacement hormones (such as Euthyrox or Letrox), these should be exceptionally be taken after the blood test.
