The Mold Spores Allergy panel is an IgE blood test that detects sensitization to five common mold spore allergens: Alternaria tenuis, Aspergillus fumigatus, Candida albicans, Cladosporium herbarum, and Mucor racemosus. It measures allergen-specific IgE antibodies produced by the immune system from a single blood sample. A healthcare provider may order it when someone has year-round respiratory or skin symptoms that could be linked to indoor or outdoor mold exposure. Results are a screening tool and are interpreted with symptom history and environment.

• Alternaria tenuis-specific IgE Antibodies against Alternaria tenuis spores; a common outdoor and indoor mold.
• Aspergillus fumigatus-specific IgE Antibodies against Aspergillus fumigatus spores; a mold found in soil and damp indoor spaces.
• Candida albicans-specific IgE Antibodies against Candida albicans; a yeast-like fungus included in the mold panel.
• Cladosporium herbarum-specific IgE Antibodies against Cladosporium herbarum spores; a widespread environmental mold.
• Mucor racemosus-specific IgE Antibodies against Mucor racemosus spores; a mold associated with damp organic material.

• People with year-round sneezing, congestion, or cough of unclear cause
• Individuals who notice symptoms in damp or musty indoor spaces
• Those with asthma or eczema that may be triggered by mold exposure
• People who suspect mold sensitivity after water damage or high humidity
• Anyone whose provider wants several mold markers checked together

• No fasting is required for this IgE allergy panel
• The sample can be collected at any time of day
• Tell the healthcare provider about all medications you take
• No special diet is needed before collection

Each mold is reported with its own IgE level or class. A value above the reporting threshold may indicate sensitization to that mold, but sensitization does not always cause symptoms. Low or undetectable levels make allergy to a specific mold less likely without ruling it out entirely. Different molds can share proteins, so a provider may consider cross-reactivity when several markers are elevated. Discuss results with a healthcare provider before changing your environment or routine.
