• Lipemia.
• Grossly contaminated.
• Icteric.
• Other body fluids.
• Specimens not collected and processed as indicated.

In-Lab Processing

Laboratory

Sent to Quest Diagnostics Nichols Institute, San Juan Capistrano, CA.

Performed

Monday, Wednesday – Saturday.
Results available in 2-4 days.

Reference Range

C. albicans IgG: <1.0
C. albicans IgA: <1.0
C. albicans IgM: <1.0

Interpretive Criteria
<1.0 :Antibody Not Detected.
≥1.0 :Antibody Detected.

Test Methodology

Enzyme-linked Immunosorbent Assay (ELISA).

Interpretation

Systemic candidiasis is often characterized by markedly elevated levels of Candida-specific antibodies. However, interpretation of Candida antibody results is complicated by detection of these antibodies in healthy individuals, and blunted antibody responses in immunocompromised patients.

Clinical Utility

Candida albicans Antibodies (IgG, IgA, IgM) – Candidiasis is a fungal infection that may cause localized or systemic disease. The severity of infection is broad extending to life threatening. Acute or convalescent titers should be compared.
