Diagnosis of Aspergillosis
Your doctor will speak to you about your symptoms and review your medical history for conditions that make you open to the illness. Testing for invasive aspergillosis usually involves doing a biopsy to sample and test lung tissue. Your doctor may also insert an instrument through your mouth or nose to reach your lungs and collect a small amount of fluid for fungal testing.

Other tests may include:
blood tests to check for antibodies, allergens, and fungus molecules
a chest X-ray
a CT scan of your lungs
a sputum stain and culture to examine your bronchial mucus
