How the swab test is done

The PCR swab test is done by the patient themselves and not by staff at the practice You can book a collection slot online to pick up the kit at our practice in Marlow. You make payment for the test at the same time as booking your slot. Please do not enter the practice to collect the kit, the reception team will be aware of your collection time and will bring the kit out to you. All instructions on using the nasal swab are within the kit. We ask you to drive to the practice so that you can do the swab in your vehicle in our car park. If you don’t have a suitable vehicle, we can arrange for you to use our side entrance to take the swab inside the practice. Please confirm this before attending.
We also ask that you bring a photo ID with you to confirm your identity. The kits are to be sealed and deposited at the practice in a special collection container at our front entrance. We will arrange courier collection for the swab to go to the London laboratory Results from the test will be emailed to you.
