“Quidel is pleased to be entering into a mutually beneficial alliance with a globally respected diagnostics leader that increases the reach of our products to markets around the world. Our intention is to create a partnership for co-development of a pipeline of new, high-value point-of-care tests intended to be sold in the U.S. by Quidel and in the rest of the world by bioMérieux exclusively,” said Caren Mason, president and CEO of Quidel Corporation.

“We are delighted with this very synergistic partnership with Quidel,” said Stéphane Bancel, CEO of bioMérieux. “Quidel is recognized for the high quality of its products and its focus on providing accurate and cost-effective solutions to detect and minimize the spread of infectious diseases. Together, we will establish a global brand supporting clinicians’ decisions at their patients’ point-of-care,” he added.
