Test Methodology

Latex Agglutination.


A negative reaction does not exclude the possibility of systemic candidiasis. A consistently high titer (¿ 1:4) or a rising titer is suggestive of invasive candidiasis. False positive results may occur in patients with acute renal failure. Rheumatoid factor can cause nonspecific agglutination.

Clinical Utility

This assay aids in the diagnosis of of systemic candidiasis.
