Abstract
False-Positive Cryptococcal Antigen Test Associated with Use of BBL Port-A-Cul Transport Vials ▿ Deborah A. Wilson , Mary Sholtis , Sharon Parshall , Gerri S. Hall and Gary W. Procop * Section of Clinical Microbiology, Cleveland Clinic, Cleveland, Ohio ABSTRACT A total of 52 residual CSF and serum specimens, which were originally negative with the Cryptococcal Antigen Latex Agglutination System (CALAS), were shown to become falsely positive after placement in BBL Port-A-Cul anaerobic transport vials. This transport device, although excellent for specimen transportation for subsequent culture, should not be used if cryptococcal antigen testing is needed.
