Quest, one of the nation’s top commercial laboratory companies, has dialed up testing as the pandemic increasingly infects American citizens. Quest’s journey to helping aid in the COVID-19 pandemic sweeping across the United States began seven weeks ago when the Food and Drug Administration authorized the commercial lab company to move forward with developing and running its own test, under a temporary emergency authorization.

Quest Diagnostics, through its “Peace of Mind” program, is taking extra measures to ensure individuals who are the most vulnerable to adverse COVID-19 outcomes have special access to the company’s 2,250 patient service centers across the United States. Through this new program, individuals who are 60 years or older – or have other conditions known to raise the risk of an unfavorable outcome from COVID-19 – will have special access to centers during the first hour of each day each center opens.
