Pneumonia | Diagnosis & Tests


How does my doctor know I have pneumonia?

Your doctor will diagnose pneumonia based on your medical history and the results from a physical exam. He or she may also need to do some tests, such as a chest X-ray or a blood test. A chest X-ray can show your doctor if you have pneumonia and how widespread the infection is. Blood and mucus tests can help your doctor tell whether bacteria, a virus or a fungal organism is causing your pneumonia.
