Moderate to low-risk medical devices and in-vitro diagnostic manufacturing facilities are inspected at the discretion of the Authority, based on the inherent risk of their products.

Quality Audit Objectives

The audits are designed to:

  1. determine conformance of a manufacturer's quality system with regulatory requirements;
  2. determine the effectiveness of the implemented quality system for the purposes of meeting specified quality objectives;
  3. ensure that corrective actions agreed in various audits have been implemented effectively;
  4. ensure that corrective actions agreed in the previous audit have been completed effectively;
  5. ensure that, the products are consistently manufactured according to agreed standards and specifications submitted during market authorization; and
