What does the Candida albicans IgG antibody test measure?

Why is Candida albicans IgG antibody measured?

Candida IgG in environmental panels is controversial; its inclusion reflects functional-medicine interest in chronic candidiasis and 'dysbiosis,' concepts not universally accepted in mainstream gastroenterology and infectious disease. Elevated IgG may correlate with recurrent mucosal candidiasis but does not diagnose invasive infection, which requires culture or histopathology, nor does it confirm the systemic 'yeast syndrome' posited by some practitioners.

Reference ranges

Standard reference

Negative or low; laboratory-specific cut-off.

Functional medicine optimal

Low or negative; detectable IgG is common in healthy individuals and interpretation depends on titre magnitude and clinical correlation.

Units

Arbitrary units, Qualitative result

Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
