From Ink Pens to Computers: A Personal Look Back at Landmark Changes during 5 Decades as a Clinical Laboratory Scientist in U.S. Hemostasis Laboratories.

In 2023, Seminars in Thrombosis and Hemostasis will be celebrating its 50th anniversary, and similarly this will also mark my 5th decade of working in, or association with, laboratories that perform hemostasis testing. My career started at a large military medical center, but I also worked at several other facilities, including military dispensaries, community hospitals, and a large academic institution. The difference between each type of hemostasis laboratory was as expected, with larger facilities having better instrumentation and more prolific test menus. However, whether one worked in a large academic center, or a small rural hospital, regulatory changes affected every clinical laboratory to the same degree. Advances in technology also eventually affected every hemostasis laboratory, but these salient changes were more likely to occur earlier at the larger institutions. As Seminars in Thrombosis and Hemostasis celebrates its 50th anniversary, that milestone triggered recollection about those salient events that occurred during my own career in hemostasis testing. As such, I describe (my impression) the top ten landmark changes that altered laboratory practice at the facilities where I worked during the past 5 decades.
