How Is Pneumococcal Pneumonia Diagnosed?

Diagnosis of pneumococcal pneumonia involves a combination of clinical evaluation and laboratory tests:

  • A physical exam, listening to your lungs with a stethoscope.
  • A chest X-ray to see how bad the infection is and where it is in the lungs.
  • Blood tests to check for signs of infection and inflammation.
  • A sputum culture to identify if Streptococcus pneumoniae is in the mucus from your lungs.
  • A urinary antigen test for a quick check of pneumococcal antigens in your urine.
