This test is performed by Cepheid GeneXpert.
The use of collection devices other than the dual rayon swab is not recommended. Other specimen types have not been validated with the Xpert GBS test.
False negative results may occur if the number of organisms in the sample is below the limit of detection.
Test results may be affected by prior antibiotic therapy.
DNA from non-viable organisms may be detected. A positive result is presumptive for the presence of GBS.
