As a followup to the July 30 Discordant PT Results, George presented this problem to a colleague in the booth of one of the major hemostasis materials distributors in the Clinical Laboratory Expo, thereby “spoiling his day.” Nevertheless, he had the answer by days’ end, confirming the response posted by Dr. Vadim Kostousov. This was further confirmed by Dr. Emmanuel Favaloro on July 3. Thanks to all who contributed to this interesting case.
