Serum total IgE > 1000ng/ml, although a typical finding in ABPA patients,[17] is neither sensitive nor specific for the diagnosis of ABPA as lower levels are expected in patients with fibrotic end stage disease, in patients in remission (stage II) and in patients on oral corticosteroids.[7] Of the two patients who had serum IgE levels less than 1000 ng/ml, one was on oral corticosteroid for the relief of asthma and the other had end-stage disease. Here, IGHE is linked to asthma.
