Cryptococcus Antibodies, Quantitative

Test ID: 

706067

CPT code:

86641

Clinical Use:

Aid in the diagnosis of cryptococcosis

Test Information:

Agglutination titers ≥1:2 are suggestive of infection with Cryptococcus neoformans. Agglutinins may be detected early in the course of the disease but if the disease progresses, excess antigen may be produced which renders antibodies undetectable. With effective chemotherapy, the antigen titer declines and antibody may once again be demonstrated. Antibodies may persist for long periods even after cessation of chemotherapy.
