Tests and diagnosis

By Mayo Clinic Staff

To diagnose Q fever, your doctor will perform one or more blood tests, along with additional tests if chronic Q fever is suspected.

Lab tests

Your doctor may want to check your blood for antibodies to the Coxiella burnetii antigen and for evidence of liver damage.

Imaging tests

  • Chest X-ray. Q fever can cause pneumonia in some people. A chest X-ray can be used to see if your lungs look healthy.
  • Echocardiography. If chronic Q fever is suspected, your doctor may do an echocardiogram to check for problems with your heart valves.
