A titer is performed on all positive specimens. Titer results are reported to the client. The College of American Pathologists (CAP) requires that Cryptococcal antigen detection testing performed on CSF specimens be confirmed by culture (CAP MIC.42005). When Cryptococcal antigen detection is ordered on CSF specimens by the University of Utah Hospital, Huntsman Cancer Hospital, or the VA Hospital of Salt Lake City, a CSF culture will be ordered automatically (see ARUP Test Code 0060106 for submission requirements). All other specimens will be processed with the assumption that a culture was performed before sending to ARUP unless a specific request for culture is included with the test order. Additional charges apply.
