A 62-year-old woman presented to the emergency department with abdominal pain and weakness; she has a medical history significant for end-stage renal disease secondary to focal segmental glomerulonephritis status after directed donor kidney transplantation two years ago. A computed tomography (CT) scan revealed pneumoperitoneum. She emergently underwent exploratory laparotomy with distal gastrectomy and gastrojejunostomy.

Upon admission, her platelet count was 96 × 103/µL (reference range [RR], 150-450 × 103/µL), approximately five days post-surgery her mental status waned, and platelet count decreased to 9 × 103/µL.

Other notable tests produced the following results:
