Biomarker Reference · Penicillium IgE
Penicillium notatum-specific IgE (Penicillium IgE) is a clinical biomarker used in environmental-mould assessment. Penicillium species, including Penicillium notatum (now Penicillium chrysogenum), are widespread indoor and outdoor moulds found in soil, food spoilage, and damp indoor environments. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Penicillium species, including Penicillium notatum (now Penicillium chrysogenum), are widespread indoor and outdoor moulds found in soil, food spoilage, and damp indoor environments. Spores become airborne and can provoke IgE-mediated allergic reactions in sensitised individuals, contributing to perennial allergic rhinitis and asthma.
Detection of Penicillium-specific IgE confirms sensitisation in patients with perennial rhinitis or asthma worsened by indoor dampness. It is particularly relevant in occupational settings (e.g., food processing, agriculture) and in homes with visible mould or water damage.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
