title: A case of extravascular hemolysis with Tk-activation.
abstract: A 50-year-old female with ovarian cancer for 4 years presented with abdominal pain. She started antibiotics for possible infection, and developed extravascular hemolysis. All antigen detection tests were negative, but lectin panel suggested Tk-activation. Additional laboratory testing in conjunction with blood bank is essential to investigate rare cause of hemolysis.
