Your general/family doctor or GP will do several things to figure out if you have CRS:
If the GP thinks further evaluation is needed, they may refer you to a specialist. In most cases a GP will treat you for CRS on the basis of your symptoms.
Specialists, like ear-nose-throat (ENT) doctors, may perform more advanced tests to confirm your diagnosis and find out what’s causing your symptoms. They might also repeat some tests already done by your GP, such as:

If the endoscopy or other tests don’t explain your symptoms, or if surgery is being considered, the ENT specialist might order a CT scan to get a detailed picture of your sinuses.
A CT scan might be recommended:
A CT scan provides a clear, detailed image of your sinuses. It shows how severe the sinus problem is. It can also reveal the exact location of abnormal tissue. This can tell your doctor how close the problem is to important parts of your head, like your eyes or brain. If surgery is needed, the scan also helps the doctor plan by showing the exact structure and layout of your sinuses.
