Microscopic examination of sterile specimens, such as those collected through needle aspiration, can help identify Aspergillus fungi infection. This is typically confirmed through histopathology, cytopathology, and/or direct microscopic examination, which reveal tissue damage associated with the infection.
Aspergillus fumigatus is a common causative agent of various respiratory conditions, including Hypersensitivity Pneumonitis, Invasive Lung Disease, and Allergic Bronchopulmonary Aspergillosis (ABPA). Elevated levels of IgG antibodies against Aspergillus are strongly indicative of Aspergillosis, helping in the diagnosis and guiding treatment decisions.
