Blood tests

Book your blood test

Our blood test appointments are provided by our pathology provider, Synnovis, at:

  • St Thomas’ Hospital
  • King's College Hospital
  • Gracefield Gardens health centre
  • Tessa Jowell health centre

You can view clinic times and book your appointment online

Please visit the Synnovis website for details on how to book if you are having trouble. 

If you're unable to book online

We are making sure our service remains flexible and are offering you different ways to book your blood test.

Same day appointments 

You can visit the clinic and we will book the next available appointment.

Some time slots are reserved for walk-in patients. However, we cannot guarantee an appointment if you haven't pre-booked.

Future appointments 

Please visit the clinic and a member of the team can help you book a future appointment. This will be helpful if you have routine tests or for when you want an early appointment because you need to fast (when you stop eating or drinking before a procedure, test or treatment). Please visit the clinic and a member of the team can help.

Booking for others (not children under 16)

Family members, friends and carers can book blood test appointments by creating their own online account and adding you to it.  

Booking at a GP practice 

GP practices may be able to make an appointment for you. Please check with your GP. 

Clinic locations for adults (over 16)

Getting to appointments at Guy’s Hospital

We’re having issues with some of the lifts in Tower Wing at Guy’s Hospital.

If your appointment is in Tower Wing, please allow an extra 15 minutes to get there, as you may need to queue for a lift.

Children's blood tests (under 16)

See the Evelina London website for information about children's blood tests including appointments, contact details and how to make a referral.

Cancer patients

See the chemotherapy page for more information about coming for your blood test.
