Neutropenia is defined by an absolute neutrophil count below which value?

Explanation:
Neutropenia is defined by the absolute neutrophil count falling below 1.5 x 10^9/L. Neutrophils are the main defenders against bacterial infections, so when their count dips under this level, infection risk rises and clinicians use this threshold to label the condition and guide management. Normal ANC is typically higher than this, usually around 2.0 to 7.5 x 10^9/L depending on the lab. More severe neutropenia is described with lower cutoffs (for example, below 0.5 x 10^9/L), but the standard definition of neutropenia is ANC < 1.5 x 10^9/L.
