Tests that measure Streptococcus

Streptococcus Group A Rapid Antigen with Reflex to Culture

Laboratory
Quest Diagnostics
Test code
10553
Specimen
Swab
Fasting
Not stated as required

What the laboratory says this test is for

Group A Streptococcus (S. pyogenes) is the most common cause of bacterial pharyngitis ("Strep throat") causing local pharyngeal pain, adenopathy, and fever. In addition, it is important to treat infections caused by this virulent organism in order to avoid potential, morbid complications including peritonsillar and retropharyngeal abscesses, bacteremia, rheumatic fever, and acute glomerulonephritis. Group A Streptococcus, however, may also be isolated in small numbers as part of the oropharyngeal flora of asymptomatic carriers.

Streptococcus Group B with Susceptibility Culture

Laboratory
Quest Diagnostics
Test code
15090
Specimen
Swab
Fasting
Not stated as required

What the laboratory says this test is for

Group B streptococci can be one of the most significant pathogens in the neonatal period. The organism is transmitted to the newborn through the birth canal. Prepartum vaginal introitus and anorectal cultures are important to determine carriage.

Culture Throat Special with Group A Strep Susceptibility

Laboratory
Quest Diagnostics
Test code
14541
Specimen
Swab
Fasting
Not stated as required

What the laboratory says this test is for

The significance of any isolate in pure or mixed culture must be assessed with respect to the source cultured, the organism's pathogenic potential, the possibility of colonization versus infection, and the number of other organisms recovered in the same culture.
