Major Commercial Healthcare Insurance Carrier

The Smart Informatics™ systems and real-time patient safety alerts have identified drug diversion and simulated compliance situations that we simply could not have identified with any other lab.

Addiction Specialist Medical Doctor

Service. Service. Service. In 30 years of practice, no laboratory comes close. I can literally call Progressive’s lab director, lab manager or other scientist on a weekend or during evening office hours for scientific insight.

Leading Pain Management Physician

Accurate and fast results are critical for my patients in recovery from addiction. Progressive understands my needs and routinely reports test results in 24 hours or sooner.

Executive Director, Intensive Outpatient Treatment Facility

Wow. Thank you. I got my COVID-19 antibody test results the next day. My mom lives in Florida and she got her results from a leading national lab 10 days later! Knowing my status was a relief.


I went yesterday and it was Great! I made an appointment and was in and out in minutes!
