Header image for the post titled Guidance for Industry: The Reference Section

Anyone working in the pharmaceutical industry must have good knowledge of the relevant regulations. While attending courses and workshops is very useful in staying up to date, there is really no substitute to reading the source documents themselves. Here is my living currated “Reference Section” of regulatory documents and guidance that I keep going back to all the time. It may be useful to anyone working in clinical sample testing and/or IVD development.
