Rhizopus nigricans Ab.IgG
Detects immune antibodies (IgG) against Rhizopus nigricans mold in your blood.
Why This Biomarker Matters
Positive results indicate exposure to this allergenic mold. Identifying mold exposure helps explain chronic respiratory symptoms and guides environmental remediation efforts.
Overview
Rhizopus nigricans is a mold commonly found in soil and decaying organic matter. This test detects IgG antibodies against the mold, indicating past or ongoing exposure. IgG antibodies suggest historical exposure rather than acute infection. Elevated levels may be seen in people with mold allergies, occupational exposure (farmers, gardeners), or those living in damp environments. This test helps identify environmental allergens contributing to chronic respiratory symptoms.
