A 2025 study published in Pediatric Allergy and Immunology examined biological markers that may help clinicians more accurately assess mold exposure in children with asthma. Researchers found that no single biomarker is sufficient on its own; rather, a combined mVOC biomarker index offers a stronger, more reliable indication of mold exposure. These findings suggest that a multi-marker approach may give healthcare providers a clearer picture of environmental mold burden in vulnerable pediatric patients.
