Tests and diagnosis

By Mayo Clinic Staff

Your doctor may suspect respiratory syncytial virus based on a physical exam and the time of year of the infection. During the exam, he or she may listen to the lungs with a stethoscope to check for wheezing or other abnormal sounds.

Your doctor may also use:

  • Painless skin monitoring (pulse oximetry) to check whether the level of oxygen available in the bloodstream is lower than usual
  • Blood tests to check white cell counts or to look for the presence of viruses, bacteria or other organisms
  • Chest X-rays to check for pneumonia
  • Lab tests of respiratory secretions from your nose that check for the virus
