When tests IGA show a defficiency what do you look for?

When tests for Immunoglobulin A (IgA) show a deficiency, it's important to evaluate for potential underlying conditions, such as common variable immunodeficiency (CVID) or other immune system disorders. Additionally, a thorough assessment of the patient's medical history, including recurrent infections, Allergies, or autoimmune issues, is essential. It's also crucial to check for possible associated deficiencies in other immunoglobulins (IgG, IgM) and to conduct further immunological testing as needed.
