What to expect
Preparing for your blood test
If you have been advised not to eat or drink anything except water for 12 hours before to your blood test, please follow these instructions.
It is important you us know if you have had any problems with previous blood tests, this could be feeling faint or if you are taking medication such as warfarin or aspirin.
During your blood test
Your test will be performed by a Phlebotomist.
An elasticated strap will be placed around your arm, the area is sterilised, and a small needle attached to a syringe, is inserted into one of the blood vessels in the inside of your elbow or wrist. You will feel a sharp prick as the needle goes in but this shouldn't be too painful.
A sample of blood is then taken and the needle is removed. You will be given a pad to put pressure on the site of the injection, which stops any bleeding and should prevent bruising.
Most blood tests only take a few minutes to complete.
It is recommended you drink a large glass of water before your test; the more water you drink, the plumper your veins become and the easier it is for the Phlebotomist to locate your veins.
After your blood test
The results are sent back to your GP or Consultant so you will need to make a further appointment to get your results. This will take about a week.
The Phlebotomy service does not receive results of patients' blood tests. They go to the health professional who requested the test so they can review the results.
If you have any questions about the test please ask the Phlebotomist.
