Blood test department (Phlebotomy) 

A blood test is taking a sample of blood for testing in a laboratory. Blood tests have a wide range of uses and are one of the most common type of medical tests.

For example, a blood test can be used to:

  • assess your general state of health
  • confirm the presence of a bacterial or viral infection
  • see how well certain organs, such as the liver and kidneys, are functioning
  • screen for certain genetic conditions

Please remember we can only perform a blood test if you bring your request forms with you.  If your GP referred you please check that your current GP’s name and address are listed on the referral form to ensure results are sent correctly.


  • Preparing for your blood test

    Please observe any special instructions your referring healthcare professional may relay to you about preparations prior to your blood tests such as:
    If your doctor has asked you to fast please do not eat or drink anything except for water for 12 hours prior to having your blood test.
    Please inform the phlebotomist if you have had any problems with previous blood tests such as feeling faint or if you are taking any blood thinning medications such as warfarin or aspirin.  You may have been asked by your healthcare professional to stop taking a certain medication prior to your test.
  • What a blood test involves

    A test usually involves placing a needle attached to a blood-collecting container into one of the blood vessels in the inside of your elbow or the back of your hand. You will feel a sharp scratch as the needle goes in but this isn't usually particularly painful.

    A sample of blood is then taken and the needle is removed. The staff will apply a cottonwool pad to put pressure on the site of the needle puncture.

    Most blood tests only take a few minutes to complete.

    If you do not like needles and injections, please tell the person who is taking the sample so they can make you more comfortable.
  • Results

    Our phlebotomists send your blood sample to our laboratory where it will be examined and/or tested with chemicals depending on what is being checked.
    Most blood test results are returned to the requesting healthcare professional within a week. 
    Results are not returned to the blood test department.
  • Oral Glucose Tolerance Test by appointment

    The only appointment we require booking for is the Oral Glucose Tolerance Test (OGTT/GTT) which is performed in our South Camden Centre for Health location during the early morning hours of operation.  This test requires fasting.  Please allow for 2 and a quarter hours for testing completion.  Please telephone 020 3182 1747 to book.
