You can find out more about blood tests, their purpose and the way they are performed on the NHS Choices website.
When you have a blood test, the doctor or nurse will tell you when your results will be available. You should telephone the practice between 11:00 am and 16:00 pm and will be given your results if they are available.
Please note: When you telephone for your results they may be given to you by a non clinical member of the practice team and therefore they will only be able to tell you that the results have been seen by the doctor.
