Which of the following must be done periodically in a Lab Certificate Program?

Periodic IA program reviews are essential in a Lab Certificate Program as they ensure that the laboratory maintains compliance with established standards and regulations. These reviews typically involve evaluating the effectiveness of the laboratory's quality assurance processes, assessing whether the current procedures are being followed, and identifying any areas that may need improvement. By conducting these reviews regularly, laboratories can ensure they continue to operate effectively and can demonstrate their commitment to quality and accuracy in testing.

While other activities such as equipment upgrades, technician training sessions, and client feedback sessions are important for overall lab operation, they do not specifically fall under the periodic requirements emphasized in a Lab Certificate Program as IA program reviews do. Reviews are structured to ensure the integrity and reliability of lab results, making them a critical aspect of maintaining certification and trust with clients.
