Celera spent years mapping the human genome, and has put that knowledge to use. Formerly a researcher, the firm is now focused on developing diagnostics and providing clinical services. Its genotyping products are used to track genetic mutations that indicate drug resistance in HIV, screen for cystic fibrosis, and identify the best matches for organ transplants. The company's Berkeley HeartLab (BHL) and 4myheart businesses provide cardiology testing and disease management services, respectively. Abbott Laboratories distributes the company's diagnostics. Celera is wholly owned subsidiary of Quest Diagnostics.
