Neutropenic fever is an oncologic emergency. If you are receiving chemotherapy, you are at particular risk of developing neutropenic fevers. Neutropenia occurs when your white blood cells, specifically the neutrophil population, becomes dangerously low.
...
Neutropenic fever may cause serious effects, including death, very quickly.

Her absolute neutrophil count (ANC), measured in cells per microliter of blood, was 0 when admitted.
"Severe neutropenia" is ANC < 500.

Next time I'll pay closer attention to a fever!
