| An absolute basophil count test is a blood test that measures the exact number of basophils, a type of white blood cell, in a specific volume of blood. It is used to diagnose and monitor conditions related to allergies, inflammation, parasitic infections, and certain blood-related diseases, such as autoimmune disorders, thyroid irregularities, and some types of leukemia. Unlike a general blood count that gives a percentage, this test provides a more precise measure of basophil levels. |
