Who We Are


MedLabs began in 1951 with a vision to provide the highest quality and most advanced diagnostic testing services. Over the years we’ve learned that by providing the best diagnostic solutions to doctors, we help them provide the best care for their patients. We’re proud to be the diagnostics company that doctors can customize to their needs and to the needs of their patients.

MedLabs' main laboratory located in Cedar Knolls, NJ performs routine STAT and esoteric clinical testing. MedLabs Diagnostics and its affiliate, MedLabs Genetics, perform over 95% of all tests ordered by clinicians.

Reference Testing
MedLabs will handle specimens run both in house and those that need to be sent to a reference laboratory, making MedLabs your one laboratory program. MedLabs has strategic relationships with all national and many esoteric laboratories including those with exclusive contracts so you have a single point of contact for all your laboratory services such as specimen requirements, test results, status inquiries and billing services.
