X-rays can show signs of tuberculosis (TB), such as lung nodules or cavities, but they are not definitive for diagnosis because these findings can also resemble other diseases. Additionally, early-stage TB may not produce visible changes on an X-ray, leading to false negatives. A positive diagnosis typically requires microbiological confirmation through sputum tests or tissue biopsies to identify the bacteria directly. Thus, while X-rays can indicate the possibility of TB, they cannot confirm it without further testing.
What else can I help you with?
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.

PTB, is the most common form of TB, which is spread through the air when a person with the infection coughs or sneezes.
