CTU: A Clinical Trials Unit (CTU) is an ACTG entity that centrally coordinates a number of Clinical Research Sites (CRS). CTUs have established robust systems that ensure high-quality conduct and delivery of clinical trials  at the CRSs that are affiliated with them

CRS: A Clinical Research Site (CRS)  a discrete location (e.g. hospital, outpatient clinic, community health center, private practice, local health department clinic) at which a clinical trial is executed. This is where participant recruitment and retention, protocol management, and other clinical research activities happen. These sites have appropriate, identified, and characterized potential trial participants (e.g. demographics, incidence, and prevalence of HIV/AIDS). A CRS is a component of a Clinical Trials Unit (CTU).
