Adding or Replacing CT Unit

An additional or replacement CT unit may be added to a facility’s currently accredited site during the three-year accreditation cycle. Accreditation is granted only for the specific testing areas for which a facility has applied and submitted an application. Though facilities may be performing other testing in the facility, those areas are not covered under the accreditation until an application for the specific testing type is submitted and granted accreditation (click here for more information).

PLEASE NOTE: Any equipment added during the three-year accreditation cycle is considered part of the original accreditation application and will expire on the current expiration date. For example, a facility adding (or replacing) a unit in December 2019, to an application that expires on January 31, 2021, the expiration date does not change.

To add or replace a CT unit to a facility’s current accreditation, the add on or replacement forms must be completed and submitted with the required case studies and other documentation. As well, the facility will be required to pay the fees associated with adding or replacing a CT unit.
