Doctors diagnose bronchitis on the basis of symptoms and a physical examination.
- Usually no blood tests are necessary.
- If the doctor suspects the patient has pneumonia, a
chest X-ray may be ordered.
- Doctors may measure the patient's oxygen saturation (how well oxygen is reaching
blood cells) using a sensor placed on a finger. This is referred to as pulse
- Sometimes a doctor may order an examination and/or culture of a sample of phlegm
that is coughed up to look for bacteria.
