Out of Crime
This is G6PD (glucose-6-phosphate dehydrogenase) deficiency. The arrows indicate bite cells where Heinz bodies have been removed (Take a Bite out of Crime). The drug described here is nitrofurantoin, an agent only used for uncomplicated E coli UTI (and prophylaxis). It can trigger G6PD hemolytic anemia.
