FAQ
Frequently Asked Questions
It is a specific and severe type of low white blood cell count, involving a near-total absence of granulocytes (neutrophils, eosinophils, basophils).
Common causes include adverse reactions to certain drugs (e.g., clozapine, chemotherapy), autoimmune diseases, and bone marrow disorders.
It can be life-threatening if not identified and managed promptly due to the high risk of severe, systemic infections.
Treatment involves stopping the causative agent, using antibiotics/antifungals to prevent/treat infection, and sometimes administering granulocyte colony-stimulating factors (G-CSF).
