Your doctor will look for an infection or noninfectious cause of your fever based on your other symptoms and a physical exam. You may need tests, such as blood tests, to confirm a diagnosis.
If you have a low-grade fever that persists for three weeks or more, but have no other symptoms, your doctor may recommend a variety of tests to help find the cause. These may include blood tests and X-rays.
