- Streptococcus Group A Direct, DNA Probe
- Gen-Probe® Group A Streptococcus Direct Test
Uses nucleic acid hybridization for the qualitative detection of group A streptococcal RNA as an aid in the diagnosis of group A streptococcal pharyngitis from throat swabs
Blood and potentially other chemiluminescent substances may interfere with this test. A negative test does not exclude the possibility that the numbers of group A streptococcal cells may be below the level of detection of the assay. Some strains of Streptococcus equi and rare strains of nonhemolytic streptococci which react with group G antisera may result in a false-positive reaction.
Swab of posterior oropharynx, tonsils, or other inflamed area
One or two swabs
Throat swabs are transported to the laboratory at room temperature within 48 hours after specimen collection. After receipt in the laboratory, specimens are stored refrigerated and tested within 72 hours.
Causes for Rejection
Throat swab that contains visible blood; improper labeling; inappropriate specimen transport device; specimen received after prolonged delay (more than 48 hours); source other than throat
