  • urine tests for kidney inflammation
  • x-rays, computerised tomography (CT) and magnetic resonance imaging (MRI) scans for chest or sinus problems
  • echocardiogram and electrocardiogram (ECG) to check your heart is healthy
  • biopsies to check if your temporal arteries, liver, kidneys, muscles or lungs are affected
  • ear, nose and throat (ENT) examinations to see if these are affected
