Penicillium notatum Ab.IgG4

This test specifically measures IgG4 antibodies to Penicillium notatum mold. IgG4 is a subclass of IgG antibodies that may indicate chronic or repeated exposure to mold antigens. Elevated IgG4 levels can be associated with allergic responses to environmental molds and may correlate with mold-related health issues like hypersensitivity pneumonitis or chronic allergic responses. This specialized test provides more detailed immune information than general IgG testing, helping clinicians assess the nature and severity of mold sensitivity and guide environmental and therapeutic interventions.
