Severe neutropenia is defined as having less than how many cells/mm3?

1000 cells/mm3
800 cells/mm3
500 cells/mm3
100 cells/mm3

The correct answer is: 500 cells/mm3

Severe neutropenia is defined as having less than 500 cells/mm3. Neutropenia is a condition characterized by a low number of neutrophils in the blood, which are a type of white blood cell important for fighting infection. Having severe neutropenia, defined as less than 500 cells/mm3, puts individuals at a significantly higher risk of developing infections due to their compromised immune function. With such a low neutrophil count, the body's ability to fight off pathogens is severely impaired, making prompt medical attention and sometimes interventions such as growth factor therapy or antibiotics necessary to prevent serious infections.
