Value of latex test in cryptococcal meningitis.

The history of a man suffering from chronic cryptococcal meningitis is presented. A series of cerebrospinal fluid and serum specimens from this patient were investigated retrospectively by latex agglutination for the presence of cryptococcal antigens. The results were related to other laboratory findings, and to the patient's clinical progress. The cryptococcal latex agglutination test was shown to be potentially useful in the diagnosis, management, and prognosis of such patients.
