Bio-Reference Laboratories also provides a comprehensive connectivity solution to physicians and laboratories nationwide through CareEvolve, its web based healthcare portal.

“The County of Bergen and the BCEDC have created an atmosphere where bio-life science companies can thrive.” said Dr. Grodman. “Our presence in the region that we serve is constantly growing. With our new laboratory addition, we can better serve our clients, increase our market share and look forward to another year of sustained growth and opportunity.”

Bergen County Executive, Dennis McNerney sees this expansion as an important advance. “The County of Bergen and the BCEDC are working hard to position Bergen County as the nation’s leading center of bio-life science technology. Since it is the largest regional clinical laboratory serving the greater New York area, the expansion at Bio-Reference Laboratories is another positive step toward achieving our goal.”

“In 2002, more than one third of all new medicines approved by the U.S. Food and Drug Administration were developed by New Jersey-based companies. New Jersey is also headquarters to 15 of the 20 largest pharmaceutical companies in the world with over 80,000 life science employees and 22,000 doctoral scientists and engineers leading the way in bio-life science research. Bergen County and the BCEDC want to make sure that our bio-life science corporations continue to lead the industry in discovery and success,” said BCEDC President, Beth R. Gorin.
