MiraVista Veterinary Diagnostics offers both antigen and antibody tests for Aspergillus. Aspergillus spores are ubiquitous in the environment and may cause sinonasal, pulmonary, or disseminated disease in animals. The antigen test is used most often for diagnosing or monitoring systemic aspergillosis, an uncommon disease that is over-represented in the German Shepherd breed. The antibody test is most useful for assisting with the diagnosis of sinonasal aspergillosis in dogs and cats.
