During the test
On arrival at our collection centre, a blood sample will be taken from you by one of our trained collecting staff. You will then be asked to drink a sweet glucose drink and blood will be collected one and two hours later. May we suggest you bring a book to read to help pass the time and a snack to have after your test.
Please note that you will be required to remain in the collection centre for the duration of the test.
