How Quest Diagnostics Makes Money

Quest Diagnostics makes money by selling medical testing services to anyone in need. It conducts a thorough diagnosis of the patient based on their condition or the prescriptions, provides the results of the testing, and gets paid for the services. Those very results are used by hospitals to cure and/or prevent a number of diseases. Most of Quest’s revenue arises from clinical testing, but a part of it also comes from molecular diagnostics.


The healthcare industry is one of the largest industries in the world today, spreading to almost every nook and cranny of the planet. Quest Diagnostics deals only in the clinical testing sector of this industry, which is also quite huge.
