    Diagnosis is made with a help of blood test measuring serum IgA, although salivary and fecal sIgA levels are also found to be absent or low. In addition, certain symptoms are also indicative of low IgA levels, these include recurring ear, sinus, or lung infections that may not respond to regular treatment even with antibiotics. Other problems include multiple food allergies, asthma, chronic diarrhoea, and autoimmune diseases such as lupus and rheumatoid arthritis.

    For more detailed information on IgA and its importance for our health please see my article 'Importance of secretory Immunoglobulin A (sIgA) for digestive and overall health'.
