Question: 1 / 400

What is the ANC count for someone with severe aplastic anemia?

500 cells/mm³

200 cells/mm³

1000 cells/mm³

50 cells/mm³

In severe aplastic anemia, the absolute neutrophil count (ANC) is significantly reduced due to the failure of the bone marrow to produce enough blood cells. An ANC count of 50 cells/mm³ indicates profound neutropenia, which is characteristic of severe aplastic anemia.

Patients with severe aplastic anemia often experience critical drops in neutrophil levels, leading to an ANC below 500 cells/mm³. The degree of neutropenia can impact the patient's susceptibility to infections and other complications. Thus, an ANC count of 50 cells/mm³ reflects the severe nature of the disease and aligns with the clinical and laboratory findings observed in patients diagnosed with this condition.
