Tests and diagnosis

By Mayo Clinic Staff

To evaluate a fever, your doctor may:

  • Ask questions about your symptoms and medical history
  • Perform a physical exam
  • Order tests, such as blood tests or a chest X-ray, as needed, based on your medical history and physical exam

Because a fever can indicate a serious illness in a young infant, especially one 28 days or younger, your baby might be admitted to the hospital for testing and treatment.
