Blood tests

Thank you for your patience

Please be aware that your visit to our clinics might take a little longer than usual. You might also notice that regular blood test results take a bit more time to come through.

This is because we recently upgraded our patient electronic health record system across our hospitals and community services.

We’re sorry for any inconvenience and appreciate your understanding.

Book your blood test

Please book your blood test online for outpatient appointments at:

  • St Thomas’ Hospital (including Evelina London patients)
  • Guy’s Hospital (GP only)
  • Gracefield Gardens
  • Tessa Jowell health centre

Online booking is a change from our previous walk-in-only service. However, there are more options and support if you're unable to book online

If you have any issues when trying to book online, please visit the clinic and a member of staff will help you and book a same day appointment.

Having a time slot means we don’t have too many people waiting in the department at one time. We will still do the same number of tests as usual at each site.

Using Swiftqueue to book

To create an account and book your blood test, visit the Swiftqueue website or use the link at the bottom of your blood test form.

You can watch a step-by-step video guide that explains how to make a booking for yourself or for someone else.

When you book online, you can see the appointment times and make a booking at a time of your choice. You can also view, reschedule and cancel your appointments online.

You need to book your blood test at the same hospital trust as you attend as an outpatient.

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.

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 (including 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.
