Candida Antigen

Test ID: 

705723

Synonyms:

Candida Ag

Clinical Use:

Determine the presence of circulating Candida antigen in patients with disseminated infection prior to the production of Candidaantibodies, particularly in immunosuppressed patients. Detection of Candida antigen in serum is highly suggestive of systemic or disseminated candidiasis.

Additional Test Information:

LimitationsA negative test does not exclude the possibility of disseminated Candida infection. Immunocompetent patients may have a negative test result due to presence of an immune complex. False-negative results may occur if the specimen has been heated due to the heat sensitivity nature of the Candida antigen. Rheumatoid factor may cause nonspecific agglutination.
