Feb 18, 2023 · Cryptococcal antigen (CrAg) is detectable in blood prior to the onset of symptomatic cryptococcal meningitis (CM), a leading cause of death among people with advanced human immunodeficiency virus (HIV) disease globally. However, the diagnostic performance of the CrAg test in serum or bronchoalveolar lavage fluid in patients with pulmonary cryptococcosis remains The cost of CRAG testing was calculated based on current actual cost in Kampala, Uganda. This test helps identify infection early, even before visible symptoms appear, and is crucial for timely antifungal treatment. 2,3 Apr 14, 2025 · Cryptococcal antigen (CrAg) testing detects the presence of antigens produced by the Cryptococcus fungus in body fluids, aiding in the diagnosis of cryptococcosis, particularly meningitis.
