LOINC’s 25th Anniversary was celebrated on February 16, 2019 with a social media blitz of timeline, photo archive and many well wishes from around the world on Twitter and the LOINC Forum.

The year 2019 marks the 250th anniversary since the Scottish physician and professor, William Cullen, published the book “Synopsis Nosologiae Methodicae”. He, and other pioneers in the field of nosology, made it easier for physicians to classify diseases and diagnose patients’ ailments as well as promote early tracking of health outcomes.
