Reference Values

Not detected (reported as detected or not detected)

This screen will not identify and isolate other causative agents of pharyngitis. Adequate specimen collection on younger patients may be difficult and thus contribute to the false-negative rate. A detected result can be relied upon as a rational basis to begin therapy.
