The Initial Investigation
Your doctor will start with a detailed history and physical exam. They'll ask about the duration and nature of your cough, associated symptoms, and potential triggers. This information helps narrow down the possibilities and guide further testing.
Imaging: Looking Inside
A chest X-ray is often the first imaging test ordered. It can reveal issues like pneumonia, lung tumors, or heart problems. In some cases, a CT scan may be needed for a more detailed look at the lungs and airways.
Breathing Tests: Measuring Lung Function
Spirometry measures how much air you can breathe in and out. It can help diagnose conditions like asthma or COPD. A methacholine challenge test may be used to check for reactive airways if asthma is suspected but not confirmed by spirometry.
