Quidel Corporation

Is it the flu or are you pregnant? Quidel can tell you quickly enough. The company makes rapid diagnostic in vitro test products used at the point-of-care (POC), usually at a doctor's office or other outpatient setting. Unlike tests sent off to a lab, POC tests can be read on the spot. Quidel's leading products are diagnostics for infectious diseases (such as influenza and strep throat) and reproductive health, sold under the QuickVue, D3 Direct Detection, and Thyretain brands. The company also makes diagnostics for streptococci, chlamydia, and the ulcer-causing H. pylori bacterium, as well as Sofia, a next generation, rapid, immunofluorescence-based, point-of-care diagnostic test system.
