Agranulocytosis is a medical term used to describe a condition in which the body lacks white blood cells known as granulocytes. This condition can lead to a weakened immune system, making it easier for infections to occur. Some common synonyms for agranulocytosis include granulocytopenia, leukopenia, and neutropenia. These terms are often used interchangeably to describe a decrease in the number of granulocytes in the blood. Other related terms include pancytopenia and myelosuppression, which refer to a decrease in all types of blood cells. It is important to seek medical attention if you experience symptoms of agranulocytosis, as it can be a serious condition that requires prompt treatment.
