Doctors check for a sinus infection through a physical examination, inquiring about symptoms, and potentially using nasal endoscopy to view the sinuses directly. They might also order imaging tests like a CT scan to get a detailed look of the sinus cavities. In some cases, a sample of nasal discharge may be taken to identify the type of infection. These methods help determine the presence and severity of the infection.
