Approximately 90 - 95% of patients with histoplasmosis have detectable antibodies.  CF titers>=1:8 are generally considered evidence indicative of histoplasmosis.  Positive titers are also seen with fungal infections other than histoplasmosis, and confirmation of antibody specificity with immunodiffusion procedures is recommended.
