Its flagship MycoMEIA Aspergillus urine assay, which received FDA 510(k) clearance in August 2025 and CE approval for the EU, replaces invasive bronchoalveolar lavage procedures used to detect aspergillosis in transplant recipients, cancer patients, and immunocompromised individuals. The company is extending the same antigen-detection platform to other fungal and bacterial pathogens, including a Pseudomonas assay for cystic fibrosis patients.
