Ealing Hospital NHS Trust

Blood tests (Phlebotomy department)

The Phlebotomy department, based in the outpatient department, is a walk-in service where the patients take a ticket and wait their turn. The waiting time can sometimes take anything up to an hour.  Note: appointments are not made.


The department sees approximately 250 patients each day. This includes patients from the outpatient clinics, GPs and the community.


Patients with fasting requests eg cholesterol/lipids/glucose should arrive in the morning.  Patients must have nothing to eat or drink from 10pm the night before the test (except water which should be encouraged).

Special tests eg glucose tolerance test, gastrin levels and chromosome analysis can be arranged by ringing our direct line on 020 8967 5399.


Method of referral

Blood requests will only be accepted during opening times with the following information on the form:


  • Patient’s full name

  • Date of birth/hospital number

  • Clinical details

  • The GP's address/practice code in order for the result to be returned


All children aged 16 years or under must be accompanied by an adult, otherwise a test will not be carried out.


The department should be informed prior to appointment of patients with special needs ie physical or mental.
