Aspergillosis

How is the infection diagnosed?

It is often difficult to make the diagnosis. The history and physical exam may cause the healthcare provider to suspect aspergillosis. Chest x-rays sometimes show certain abnormalities that suggest aspergillosis. A blood test called aspergillosis precipitin, and an aspergillosis antigen skin test can confirm the diagnosis.

Often, a tissue sample from the lungs is needed. This is usually obtained with a procedure called bronchoscopy. In bronchoscopy, a thin tube with a camera on the end of it is placed through the mouth and down into the lungs. Samples can be taken through the tube and are then sent to the lab to see if they contain Aspergillus.
