Testing for treatment
If harmful bacteria have been identified in the throat culture, the laboratory will do additional tests using different types of antibiotics to see which one is most likely to stop the infection. This test starts by coating the surface of another agar dish with the bacteria. Known concentrations of antibiotics that have been absorbed into white paper discs are placed on the plate. If an antibiotic stops the bacteria on the plate from growing, it appears as a clear halo around the disc. This tells the doctor which antibiotic they can prescribe to cure the throat infection.
