Better health outcomes with cutting edge technology and faster diagnostics

Headquartered in Miami, FL, CDR Laboratories (CDR Labs) is dedicated to providing fast and accurate test results to improve health outcomes and minimize recovery times. Our services are tailored and scaled to meet the needs of large healthcare organizations, small private clinics, and everything in between.

As a CLIA + CAP life science laboratory, we specialize in pharmacogenetics, which can help physicians determine the right patient medication and dosage and lead to better health outcomes. To do this, we emphasize speed of results reporting, because the faster results are ready, the faster a patient can be on their way to recovery.

In addition to pharmacogenetics, CDR Labs provides molecular, chemistry, toxicology, and hematology testing. With a staff of clinical professionals, state-of-the-art facilities, and industry-leading turnaround times, our patient-centered diagnostics work for you.
