Basopenia is a medical term used to describe the condition of having a low number of basophils in the blood. Basophils are a type of white blood cell that play an important role in the body's immune system, specifically in the inflammatory response. The term "basopenia" is a combination of the Greek words "basos" for base and "penia" for deficiency. Some synonyms for this medical condition include basocytopenia, basophil deficiency, and basophilic leukopenia. It is important to note that basopenia can be a symptom of various diseases, such as allergies, infections, and autoimmune disorders, and it should be evaluated by a medical professional.
