Outpatient Diagnostic Services at Fort Duncan Medical Center

The Outpatient Diagnostic Center (OPDC) provides healthcare services for people needing outpatient diagnostic testing.

The OPDC registration clerk, located in the main lobby of the hospital, registers patients needing pre-operative testing, diagnostic services (laboratory, X-rays, respiratory care) and makes appointments for special radiological procedures. For the convenience of our patients, we try to keep waiting time to a minimum.
