You will see that your return envelope already contains a Royal Mail Tracked 24 return label. Once you have finished packing your test, all you have to do is seal the envelope and drop it at the nearest Royal Mail priority postbox, so that we receive it at our lab as soon as possible.
From its arrival at the lab, it will take us up to 24 hours to send you your results.
Please note that Royal Mail are experiencing delays at the moment. We will send you an email once your sample has reached our laboratory.
