LabGuide 28: Throat Cultures and Rapid Antigen Tests for Streptococcus
Read LabGuide 28 and be able to:
- Describe the techniques necessary to obtain an adequate specimen.
- Compare and contrast rapid antigen detection tests vs culture methods in terms of complexity, procedure, and quality control requirements.
- Discuss the use of the bacitracin disk and evaluation of hemolysis as they pertain to testing for Streptococcus.
- Given beta hemolytic colonies on selective Streptococcus agar plates, along with inhibition of growth by the bacitracin disc, correctly presumptively identify the organism as Group A Streptococcus.
- State the proficiency testing requirements associated with testing throat cultures for Streptococcus.
