Verified step by step guidance

Begin by understanding the term 'neutropenia'. It is derived from 'neutro-' referring to neutrophils, a type of white blood cell, and '-penia' meaning deficiency.

Recognize that neutrophils are crucial components of the immune system, responsible for fighting off infections, particularly bacterial infections.

Identify that neutropenia is characterized by an abnormally low count of neutrophils in the blood, which can lead to increased susceptibility to infections.

Differentiate neutropenia from other conditions: it is not an increase in white blood cells (which would indicate an infection), nor is it related to red blood cells or hemoglobin levels (as in anemia).

Conclude that the correct explanation of neutropenia is that it is a condition characterized by an abnormally low number of neutrophils in the blood, leading to potential immune system compromise.
