How is tonsillitis diagnosed?
Your health-care professional will conduct a physical examination, with special attention to the throat and neck area. Tonsillitis caused by viruses may look very similar to bacterial tonsillitis, therefore diagnostic testing (for example, throat culture, rapid strep test) may be required to differentiate between the two potential causes.
Your health-care professional will pay special attention to the following findings:
Your health-care professional also may order a rapid strep test, which requires a swab from the back of the throat area. Results of the rapid strep test are generally available within 30 minutes. Sometimes a strep culture is sent to the lab for confirmation of strep infection, though this result may require 24-48 hours. In rare instances of severe or complicated tonsillitis, blood tests and/or imaging tests may be ordered. Furthermore, if other conditions that cause a sore throat are suspected, additional testing may be necessary.
