Walk-ins Welcome – Find a location

Progressive Diagnostics offers same-day results for COVID-19 antibody tests at our Wilton and Bridgeport patient service centers.

Our FDA-EUA antibody tests have a sensitivity (true positive rate) of 100% and a specificity (true negative rate) of 97.4%, giving you peace of mind that your body is producing COVID-19 antibodies following an infection or vaccination.

You should consider taking a COVID-19 antibody test if you:

• Had COVID-19 -like symptoms in the past but were not tested for COVID-19.
• Tested positive for COVID-19, or were vaccinated, to see if you are producing antibodies.

A COVID-19 antibody test does not detect a COVID-19 infection. If you have been exposed to someone with COIVD-19 or are experiencing COVID-19 symptoms, schedule a PCR test today.

Our COVID-19 antibody test is simple. A small blood sample is collected by our trained phlebotomists at a designated patient service center. Samples are sent to our lab for processing, and you will receive your test results the same day.

Antibody tests are currently covered by insurance but may require a physician’s order.

Select “Schedule My Test” to schedule your test today.

Walk-ins are welcome at our Wilton and Bridgeport patient service centers.

If you have any questions about our COVID-19 antibody test, our customer care team will be happy to assist you. Simply call 888-503-8803 to reach a Progressive Diagnostics customer care representative or email [email protected].

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!
