Doctors can perform a strep throat culture on an individual to see if the person has it. How it is done is the doctor takes a swab and scrapes the infected area in the throat, usually on the tonsils. The swab is then sent to the lab for analysis. There is a rapid strep test available that can detect the strep within a matter of minutes.

Please remember that a strep culture is not always necessary when determining if an individual has strep or not. Strep is characterized by white pus filled spots on and around the tonsils. In addition, a person does not need to have tonsils to get strep. I had strep throat about two months ago and had a tonsillectomy about eight years ago. The strep did attach itself to left over lymph tissue in my throat.

A common antibiotic to give a person who has strep throat is amoxicillan.

There are several signs which leads to the conclusion of having strep throat, so, if occure the followings: swollen  and red tonsils and the lymph nodes on the neck's sides, throat which is presenting red or white patches,difficult swallowing, headaches and stomachaches,fever,sick,nausea.

To establish the correct diagnosis, not just one based on evidences, the doctor can test if it's strep throat, by taking a sample of fluids, which collects them from the back of the throat and in about 5 minutes can find the result. If the result is a good one, despite obvious signs of strep throat, the doctor could send the sample to the lab for a throat culture, which will establish, in about 2 days, the proper diagnosis.
