TB (PPD) testing and or quantiferon is required for all new UC Davis Health System employees (policy # 2164 –V-A #2). Annual testing is required for employees with patient contact, use elevators with patients or go to the cafeteria. For persons who test positive, a baseline chest x-ray will be required along with a yearly symptom interview and a quantiferon blood test. Chest x-rays are not routinely done, but will be ordered by employee health only if symptoms have changed.
Each employee will receive an email notice yearly as a courtesy, reminding them to complete their annual testing. There is a grace period of 10 days after the 90 day notice to have the test completed, otherwise you will be requested to be at risk, being taken off work by your manager until the test is completed (also stated in policy # 2164).
Managers are notified of employees who are 30, 60 or 90 days late for testing. Employees will not be removed from the list until the test is completed. This alerts managers to have the employee complete their PPD when they return. The managers will receive a monthly list of all employees who are outstanding for non-compliance.
Monthly email notices for TB are specific for those who require a PPD, or quantiferon or a symptom interview. For those who are positive a TB symptom interview can be done on line via the EHS website.
