Where can I get a blood test?
You may be able to have a blood test at your GP surgery, providing the surgery you are registered with has agreed to offer this. Please contact your GP surgery for more information.
If your GP referred your child for a blood test but the surgery does not offer a blood test service for children please call 020 8869 2915. Please note that all GP referrals should use this number. You can call this number from Monday to Friday from 10.30am to 12.30pm. Appointments can be booked for children under age 16.
Note: We no longer provide the phlebotomy service for people over the age 18. You will need to contact your GP practice to find the nearest place where this service is offered.
If your child is under 10 years old and a Northwick Park or Central Middlesex consultant has requested a blood test please call 020 8869 3131. Please note we will only accept Northwick Park or Central Middlesex consultant’s referrals on this number. You can call this number from Monday - Friday from 9am to 3.45pm.
If your child is aged 10 years or above and one of the consultants form Northwick Park or Central Middlesex has requested a blood test, you need to go to the main phlebotomy department that is located behind the main reception desk. This is a walk-in clinic and it is open from Monday to Friday from 8am to 4.30pm.
If your child was referred for a blood test from any other service (community paediatric, another hospital, health visitor, midwife etc) please call 020 8869 3131 from Monday - Friday from 9am to 3.45pm.
