The Centor criteria are a set of criteria which may be used to identify the likelihood of a bacterial infection in patients complaining of a sore throat. They were developed as a method to quickly diagnose the presence of Group A streptococcal infection or diagnosis of streptococcal pharyngitis in "adult patients who presented to an urban emergency room complaining of a sore throat."
A throat culture is the gold standard [21] for the diagnosis of streptococcal pharyngitis, with a sensitivity of 90–95%. [13] A rapid strep test (also called rapid antigen detection testing or RADT) may also be used. While the rapid strep test is quicker, it has a lower sensitivity (70%) and statistically equal specificity (98%) as a throat ...
A rapid strep test may assist a clinician in deciding whether to prescribe an antibiotic to a person with pharyngitis, a common infection of the throat. [1] Viral infections are responsible for the majority of pharyngitis, but a significant proportion (20% to 40% in children and 5% to 15% in adults) is caused by bacterial infection. [2]
Infections caused by the Strep A bacteria can be potentially life-threatening.
To help us with these questions, I spoke with CNN wellness expert Dr. Leana Wen. Wen is an emergency physician and clinical associate professor at the George Washington University. She previously ...
The type of infection is found using a microscope, chemical tests, or both. If no infection grows, the culture is negative. Common infectious organisms tested for by a throat culture include Candida albicans known for causing thrush and Group A streptococcus known for causing strep throat, [1] scarlet fever, and rheumatic fever.

Identifying and diagnosing alpha-hemolytic Streptococcus is done with a sputum gram stain and culture test. [5] Further identification can be done serologically to test for the presence of capsular antigen, which is the dominant structure on the surface of S. pneumoniae .
Your doctor will discuss your symptoms and medical history and complete a medical exam, which usually includes an oral and neck exam, Dr. Abu-Ghanem says. Then, they may refer you to a ...
