Anything that goes into people is made under GMP conditions. To retrofit a small lab into a GMP facility and maintain standards to pass inspection, let's just say one could eat off the floor, not that anyone would though. It requires a level of sterility and monitoring that few labs can provide or maintain because it is very costly. I know many labs losing contracts because they fail to maintain these standards. However, in the global economy pharma often outsource production to China, South America, Africa..etc, where contract labs will do the GMP work. If you are referring to that, I would not vouch on how clean those GMP facilities are. As a side note, an aquaitance of mine is the manufacturer of all pregnancy test sold in the US. Althought not GMP rated, his facilities across the boarder and in Africa are cleaner than most labs in the US.
