Summary

This study looks at whether a saliva sample can be used instead of a throat swab to diagnose Group A Strep (strep throat) in children. Throat swabs can be uncomfortable, especially for kids, while collecting saliva is much easier. Researchers will compare saliva testing to standard throat swab methods to see if it works just as well, and also test faster lab techniques that could give results in hours instead of days.
