Special Instructions: The sensitivity of antigen detection is greater using urine than serum specimens, 92% vs. 82% respectively, in disseminated disease. Antigen is detected less frequently in patients with self limited disease-39% and chronic pulmonary histoplasmosis (21%). In cases of acute pulmonary infection, the sensitivity is greater than 75% for more severe cases presenting with diffuse pulmonary infiltrates and respiratory insufficiency.
