Phadia

Phadia is a Swedish in vitro diagnostics company focused on blood-based testing for allergy, asthma, and autoimmune diseases. The business is best known for its ImmunoCAP allergy diagnostics franchise and EliA autoimmune testing products, which are used by clinical laboratories and healthcare providers worldwide. Phadia develops, manufactures, and markets instruments, assays, and related software for immunodiagnostics rather than therapeutic drug products. The company was acquired by Thermo Fisher Scientific in 2011 and operates within Thermo Fisher's specialty diagnostics business. Its core value proposition is clinically validated, laboratory-based immunoassay testing that supports diagnosis and disease management in allergic and autoimmune conditions.
