All test kits are delivered to your home and include a prepaid box for you to send your sample to the lab.
To return your blood test kit, place your box in a Royal Mail post box or your local post office.

Please do not complete your test or return samples on a Friday, Saturday, Sunday or bank holidays.
We advise that samples be collected in the morning and returned immediately using the labels provided. This is to ensure they are delivered to the lab the same day and so the sample is in the best condition for testing.
