I am a nurse and I want to be clear before anything else that nothing I say here is clinical advice to anybody, including on whether to do any of this at all.
On the narrow question of documents: the FGP set is the most complete I have handled. Method, wavelength, water content, lot code, all on one page and laid out so you can find each of them without hunting.
I saved my own independent report and compared it against the published figure. They matched. That is one lot, and it is the lot I can speak about.
