Agranulocytosis is a serious condition characterized by a dangerously low level of neutrophils, a type of white blood cell essential for fighting infections. This reduction can make individuals highly susceptible to infections, leading to symptoms such as fever, chills, and sore throat. It can be caused by certain medications, autoimmune disorders, or bone marrow diseases. Diagnosis typically involves a complete blood count (CBC) to measure white blood cell levels. Treatment focuses on addressing the underlying cause and may include medications to stimulate white blood cell production or antibiotics to manage infections. Prompt medical attention is crucial for recovery.
