Symptoms and a physical examination are all the doctor needs to diagnose the common cold. An initial diagnosis often is made from symptoms alone.
- Usually, no blood tests or X-rays are necessary.
- During the physical examination, the doctor will pay careful attention to the head, neck, and chest.
- The doctor will examine the eyes, ears, throat, and chest to help determine if a bacterial source is causing the illness.
