Blood tests are carried out to help in the diagnosis, care and treatment of various health conditions and diseases and they may be requested by your GP, your specialist team or nurse. They will give you a blood test form and provide you with information about preparation for your test. This will include:

  • For glucose test- have nothing to eat for 12 hours; drink only water
  • For cholesterol tests- have nothing to eat for 12 hours; drink only water
  • For fasting lipids- have nothing to eat for 12 hours; drink only water
  • Drinking water makes it easier to take your blood
  • If you are having a fasting blood test, medication taken with food will need to wait until after the test.

On arrival to the Main Outpatient please follow the sign for Blood test, and take a seat in the Phlebotomy waiting area you will be called at your appointment time.

Please note that some patients may be seen before you due to their need and other services that are running in the department.

It is helpful if you are wearing garments with sleeves that can easily be pushed up over your elbow or have short sleeves.

Results of your tests will be returned to the person who requested the tests.

Fasting blood tests

Your GP may request you attend for a fasting blood test. This may be for glucose tolerance, lactose tolerance or lipid/cholesterol testing.

For these tests, you should have no food or drink – except water – for up to 12 hours before the test, no alcohol for 16 hours before and no smoking for 12 hours before.

You can drink water while fasting – but not more than the amount of fluid you would usually drink. Please take any prescribed medication with water only.

If you do not comply, the blood test may need to be repeated.

Diabetic patients

  • If you are an insulin-dependent diabetic attending for a fasting blood glucose test, please inform a member of staff on your arrival
  • If you are a diabetic patient on insulin, have your fasting blood test then take your insulin as usual with your breakfast
  • If you are taking oral hypoglycaemic tablets, have your blood test and then take your tablet with your breakfast
  • Carry your blood glucose meter in case you need to use it
  • Because of the waiting period, it is advisable for you to bring in something to eat after your blood test.
