How do healthcare providers diagnose basophilia?

Healthcare providers typically diagnose basophilia by taking samples of your blood so they can perform a test called a complete blood count (CBC). This test shows the number and condition of your white blood cells, your red blood cells and your platelets.

Since basophils are a type of white blood cell, your provider may opt for CBC with differential. This test details how many basophils and other white blood cells you have.
