Name the Diagnosis in 1 Word

QUESTION: Name the diagnosis in 1 word.

ANSWER: The correct answer is babesiosis. The data shows that the patient has hemolysis (hyperproliferative anemia with how haptoglobin, and elevated LDH). A negative DAT indicates non-immune hemolytic anemia, whose causes can be divided into:

• Intracorpuscular – RBC is at fault. With exception of PNH, these conditions are congenital, so they really don’t work here
• Extracorpuscular – RBC is an innocent bystander.

Of the extracorpuscular causes, babesiosis and HELLP are the best fits. I asked for ONE WORD. HELLP is an acronym, so that leaves babesiosis, which is what the patient had.
