4X-Ray
When the symptoms keep occurring and progressing in an extended period, your doctor would take a chest X-ray. The main purpose is to find out any accumulated fluids or inflammation in the lungs. Though whooping cough does not often trigger inflammation, co-infection would result in the buildup of fluids in your lungs. An X-ray would show these problems to help the doctor make a more precise diagnosis. The results can also provide information about the strain of virus and bacteria that cause whooping cough. [4]
