How Long Is A Chest X-ray For Tb Good For?
If a regular tb test is good for one year how long is a chest xray good for? It use to be good for 2 years per medicare guidelines.
I have a chest X-ray for TB once every year. Your doctor may decide to do one more or less often. Abide by his decision. He will have a good reason for his decision regarding the time.
