Meridian Bioscience

Meridian Bioscience is a privately held life science company that develops, manufactures, markets, and distributes diagnostic and life science products. It is headquartered in Cincinnati, Ohio and serves customers in more than 70 countries. The company operates through two divisions. Its Life Science division supplies molecular and immunological raw materials used in human, animal, plant, and environmental diagnostic tests. Its Diagnostics division provides diagnostic platforms and tests for gastrointestinal infections, upper respiratory infections, and blood lead level testing. Customers include hospitals, reference laboratories, research centers, veterinary testing centers, physician offices, and diagnostics manufacturers. The company's team size and leadership structure are not publicly disclosed. In recent years, it has expanded its portfolio in next-generation sequencing (NGS), including a lyophilized DNA fragmentation kit for ambient-stable NGS workflows (per the firm, 2025). It also won the CDC's Lead Detect Prize for blood lead testing innovation. As a privately held company, Meridian does not disclose ownership or financial details. Its product portfolio and regulatory positioning differentiate it from pure-play diagnostic firms, but its governance and ownership structure remain opaque.
