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.
