Penicillium Chrysogenum/notatum IgG:
Fasting Required: No
Lab: Quest Diagnostics
Specimen: Serum
Results: Average processing time 7-10 days
Description: The test detects IgG antibodies specific to Penicillium chrysogenum (formerly Penicillium notatum) , the fungus naturally responsible for secreting penicillin. Unlike IgE antibodies (which trigger immediate, acute allergic reactions), IgG is associated with slower immune responses and chronic sensitivities. Because mold-specific IgG can simply indicate past exposure rather than an active illness, these tests are generally ordered and interpreted by specialists who factor in your symptoms and clinical history.
