What is basophilia?

Basophilia, or basophilic disorder, is a sign your body is producing too many basophils. Basophils are one of the five white blood cell types that protect your body from infections or respond to intruders like parasites, fungi and cancer cells. Basophils drive your body’s reaction to allergens. They’re why you sneeze, cough or have a runny nose during allergy season or anytime you encounter an allergen. If your basophil count is unusually high, it is called basophilia. Basophilia may be a sign you have an infection, or it may be a sign of serious medical conditions like leukemia or autoimmune disease.
