Culture of sputum, bronchoalveolar lavage, lung biopsy, cerebrospinal fluid or brain biopsy specimens on selective agar allows differentiation between the five members of the C.<unk>  species complex and the two members of the C. neoformans species complex. Molecular techniques may be used to speciate<unk>  from specimens that fail to culture. Cryptococcal antigen testing from serum or cerebrospinal fluid is a useful preliminary test for cryptococcal infection, and has high sensitivity for disease. It does not distinguish between different species of<unk> .
