Clinical Research Acronyms by PCRS Network

PCRS Network LLC is pleased to provide this comprehensive list of commonly used acronyms for reference and training.  It includes acronyms commonly used in clinical research. Obsolete or retired terms are included in parenthetical notes for reference. If we have omitted any acronyms in common use, please let us know, and we will add them.

The list is provided in two sections for ease of use, with Section 1 being in alphabetical order, and Section 2 being by category.

Additionally, we have created Clinical Research Acronyms by PCRS Network GPT for training and reference.

We hope you find these resources helpful and have fun using the GPT. Clinical Research Acronyms by PCRS Network GPT is built on the OpenAI platform. An active free or paid OpenAI account is required to access this fun and informative tool.
