A positive result confirms the diagnosis of strep throat infection. In case of a negative result, another test, known as throat culture is performed because, in many cases, the negative test does not mean that the condition is not strep throat.
Throat culture is a traditional test in which a swab is obtained from the infected throat and the growth of the bacteria is observed in the laboratory equipment called petri plate. The test takes approximately 24 to 48 hours for determining the presence or absence of the bacteria and diagnosing strep throat.
