What it measures
- Specific IgE to Rhizopus nigricans — Antibody level linked to allergic response to this mold.
- Total IgE — Overall allergy antibody level, sometimes included for context.
- Other mold IgEs — Often tested together to check for cross-reactivity or multiple mold allergies.
Preparation
No fasting or special preparation is required. Tell your clinician about antihistamines or other medications you take, as they may affect test interpretation.
Results and what they mean
Results are reported as a numerical level or class for specific IgE, often with a reference range. A higher level suggests sensitization but does not by itself diagnose an allergy. A clinician interprets results with your history and symptoms. This is general information, not medical advice.
