How can i know i have strep / tonsillitis?

See below: The most common symptoms with strep throat are a fever, sore throat, and a headache. If you have cold symptoms, it is more likely to be viral. A strep test will confirm the diagnosis, if you have strep.

Culture: The only way you can determine if you have Streptococcus as a cause of your tonsillitis is to have a swab culture directly into the tonsillar tissue. Although one can suspect it clinically, there are other bacterial causes of bacterial tonsillitis, including S. pneumoniae, Haemophilus influenza, and Moraxella catharhalis.
