Since Abbott established its business in Old Montreal in 1931, we've been dedicated to helping people live healthier lives through a diverse range of science-based nutritional products, diagnostic tools and vascular devices. With nearly 1,500 employees between our headquarters in Montreal and Toronto, our Point of Care plant in Ottawa and a lactulose manufacturing plant in Victoriaville, Abbott in Canada reflects our dedication to manufacturing the highest-quality products and finding lasting solutions to the unique health challenges facing the country. Abbott has a broad range of branded generic pharmaceuticals, medical devices, diagnostics, and nutrition products. The company's in-vitro diagnostics business performs immunoassays and blood screening. Its medical tests and diagnostic instrument systems are used worldwide by hospitals, laboratories, blood banks, and physician offices to diagnose and monitor diseases such as HIV, hepatitis, cancer, heart failure and metabolic disorders, as well as assess other indicators of health. In 1985, the company developed the first HIV blood-screening test.
