Professional Research Center has a broad database of patients with different health conditions. Our studies are nurtured by patients provided by our internal database, private practices of our Principal Investigators and hospital referrals. This guarantees us that we will not have major problems enrolling subjects for our studies.

As part of each study, we develop different strategic procedures to ensure that we are able to comply with the number of subjects assigned to us. We also keep constant communication with the subjects to ensure that they will continue in the studies until the end. All these procedures help us to achieve high enrollment and retention rates.
