Update March 2020: The vast majority of labs are still offering a full service (hoorah). Biolab has had to close due to staff safety in Central London. Any tests not available currently, I have put N/A next to them so please do not order those. I will update you with any other changes. Thanks for your patience.
If you have ordered or are thinking of ordering a test, please read these instructions to make sure everything goes smoothly. Purrleease don't email me willy-nilly unless you have read these, thank you! Note that the FAQ for ebooks and support are in those sections as this one was getting too huge!
