What does the Candida IgM Antibody test measure?

Candida IgM Antibody (Candida IgM) is a clinical biomarker used in autoimmune-inflammation assessment. IgM is the first antibody class produced during a primary immune response and can also appear during reactivation or acute exacerbation of chronic infection. It is measured in 3 laboratory tests on BiomarkersLabs.com.

Reference Range: Laboratory-specific index; typically <0.9 negative, 0.9–1.1 equivocal, >1.1 positive.
Units: AU (arbitrary units), Index value, Units (arbitrary), Arbitrary units
Measured In: 3 tests
Category: Autoimmune

Functional medicine optimalTransient low-level IgM may occur with benign mucosal exposure. Persistent or markedly elevated IgM should prompt evaluation for active infection or immune dysregulation, not assumed to represent pathology in isolation.

What is Candida IgM Antibody?

IgM is the first antibody class produced during a primary immune response and can also appear during reactivation or acute exacerbation of chronic infection. Candida IgM indicates recent or acute exposure and is particularly relevant in invasive candidiasis or disseminated infection, where it may rise before IgG. Persistent IgM can signal ongoing immune challenge or failure to clear the organism.

Why is Candida IgM Antibody measured?

Elevated Candida IgM may suggest acute or reactivated infection, particularly in the setting of invasive candidiasis in immunocompromised patients. Its sensitivity and specificity for invasive disease are limited, however, and IgM results are best interpreted alongside culture, imaging, and other fungal biomarkers. Isolated IgM elevation in an immunocompetent patient without clear clinical candidiasis may reflect recent mucosal infection or assay cross-reactivity.
