Tests and diagnosis discussion for Chronic Granulomatous Disease:

The doctor will order lab tests to look for certain blood abnormalities including an increased number of white blood cells and low number of red blood cells (anemia). Patients also often have abnormal chest x-rays, excessively high level of immunoglobulins in the blood (hypergammaglobulinemia), and elevated erythrocyte sedimentation rate or ESR (a sign of chronic infection or or inflammation). They usually have normal antibody levels. To confirm a CGD diagnosis, specialized laboratories perform various tests of the function of phagocytes, a type of white blood cell. The phagocyte’s job is to kill bacteria and fungi. (Source: excerpt from Primary Immune Deficiency, NIAID Fact Sheet: NIAID)
