Dasa

Owns 50+ lab/hospital brands including Delboni, Lavoisier, Alta, Sérgio Franco, and Bronstein; represented here as the parent/holding entity rather than each sub-brand. Consumers more often search by the specific lab brand (e.g. 'Lavoisier', 'Delboni') than by 'Dasa' itself — reflected in lower search-demand tier for the parent name. In 2025 divested Argentina and occupational-medicine operations (~R$705M) and holds 50% of Rede Américas JV with Amil. No confirmed public status page.
