Immunodiffusion and Complement Fixation (Mycelial and Yeast)
Establish presence of antibody to Histoplasma.
A recent skin test with histoplasma antigen gives a misleading rise in CF titer as well as an M precipitin band in approximately 17% of patients having previous exposure to Histoplasma capsulatum. Cross-reacting antibodies sometimes present interpretive problems in patients having blastomycosis or coccidiodomycosis.
