What is a normal basophil count?

A normal basophil count is .5% to 1% of your white blood cell count. This equals about zero to 300 basophils per microliter of blood in healthy adults. Basophil counts that fall outside this range may be a sign you have basophilia. Providers use your basophil count, along with other information such as your medical history and your symptoms, to treat the underlying condition causing your basophilia.
