North West London Pathology (Phlebotomy)

Your GP may request you come to the Phlebotomy Department for a test (eg blood test). You will normally receive an indication of the results from your GP over the telephone. If the result of the test warrants further discussion or is complex, you may be asked to make an appointment to see a doctor or nurse to get a fuller explanation. The Phlebotomy Department is working towards the national modernisation agenda, particularly looking at improved computer systems and network development across West London.

Please ensure that you bring any forms with you which your GP has given to you specifying the test procedures required - forms on a mobile phone will not be accepted. Follow any special instructions your GP has mentioned (eg fasting) in relation to those tests.

We have introduced some changes in response to Covid-19

Do not leave for your appointment if you have any of the following symptoms:

  • a high temperature
  • a new continuous cough
  • loss of smell or taste

If you are experiencing any of these symptoms follow the national Covid-19 guidance.

Please help us to protect other patients, visitors and our staff.

Please wear a face covering when you come to the hospital. Your face covering must cover your face and nose.

Please attend your appointment alone if possible as this helps us to reduce footfall.

When you enter the hospital your temperature will be checked and you will be asked a few questions. This is known as screening and is aimed at helping us to identify whether you have any symptoms that may suggest you have Covid-19.

If you are found to have symptoms you may be asked to go home and to return on another day.

Seating space in our waiting areas and the number of clinic rooms has been reduced in order to enable us to observe social distancing. At busy times you may have to queue in the corridor where floor markings have been placed to assist with social distancing. If you have a specific reason why this is likely to prove difficult please let us know.
