Aspergillus niger

This test measures the level of specific antibodies in your blood that react to Aspergillus niger, a common mold found on decaying plants and in damp indoor areas. It helps show whether your immune system is overreacting to this mold, which can explain symptoms like coughing, wheezing, or chronic sinus congestion. This information helps doctors distinguish a specific mold allergy from other respiratory conditions or different types of allergies. However, this test only identifies immune sensitization and does not diagnose an active fungal infection in the lungs.
