Once you have a positive PPD why cant you ever get it again and have to have a chest xray instead?
Once someone tests positive for the PPD skin test, that person will (almost)always remain positive for the rest of their life. Then, there is no sense in placing a PPD skin test again, as you already know that it will be positive. The reason for doing the chest x-ray instead is to make sure that there is no evidence of active tuberculosis disease in the lungs. Not all patients with a "positive PPD" will have an active lung disease from TB, which can be contagious.
