Q: Should employees who have positive PPDs continue to be tested yearly? Do they need to have a chest x-ray every year?
A: You do not need to ever repeat the PPD skin test for employees who have tested positive. Perform a chest x-ray after the first positive PPD, but do not repeat it yearly unless the employee:
- Is a recent converter
- Is a close contact of someone with TB
- Has a medical condition that increases his/her risk for TB
- Injects drugs
