This kit is intended for the in vitro qualitative detection of the nucleic acid DNA of group B streptococcus in rectal swab samples, vaginal swab samples or mixed rectal/vaginal swab samples from pregnant women at 35 to 37 gestational weeks with high risk factors and at other gestational weeks with clinical symptoms such as premature rupture of membrane and threatened premature labor.
This kit provides an auxiliary means for the diagnosis of GBS infection in pregnant women during the perinatal period. The test results are for clinical reference only, and the final diagnosis must be comprehensively analyzed with combination with other clinical indicators.
