Additional Information:

The Cryptococcus Antigen Panel is a two test combination.  Testing should be done when clinical evidence suggests diagnosis of cryptococcal disease and not as a screening procedure for the general population.   

The first test is a lateral flow assay which yields a presence/absence report for detection of the capsular polysaccharide antigens of Cryptococcus species complex (Cryptococcus neoformans, serotype A and D, and Cryptococcus gatti, serotype B and C).  It does not provide a quanitative titer of the antigen concentration.  If this test is positive, it is followed by a latex agglutination titer to obtain a semi-quantitative titer of the cryptococcal antigen in the blood or CSF.

If the initial qualitative test is negative for the capsular polysaccharide antigen, the second titration will not be run.
