The Patient Centric Sampling Interest Group was founded in October 2017 during discussions at the CPSA USA 2017 event in Langhorne, PA in a session entitled “Patient Centric Blood Sampling and Analysis: Let’s Make this Happen!” led by Neil Spooner (Spooner Bioanalytical Solutions) and Joe Siple (New Objective) and facilitated by the founder of CPSA, Mike Lee (Milestone Development Services). The session brought together a number of parties from different organizations who all had an interest in progressing these important technologies and realized that progress would be both better and faster if they were to work together.

The PCSIG was incorporated as a Community Interest Company (UK not-for-profit) in March 2023, to enable it to further expand its activities and membership.
