Streptococcus agalactiae BY PCR

Streptococcus Agalactiae BY PCR is a molecular diagnostic test that detects the DNA of Group B Streptococcus (GBS) using polymerase chain reaction (PCR) technology, typically from a vaginal–rectal swab. The assay provides highly sensitive and specific detection of GBS colonization, enabling early identification of carriers who may transmit the bacterium to newborns during delivery. With Touch Connect’s Lab at Home service, samples can be collected conveniently at home across Dubai and the UAE and processed for fast laboratory results to inform obstetric management.

The test is most commonly used for antenatal screening and in clinical situations such as preterm labor, prolonged rupture of membranes, or maternal fever during labor, where rapid GBS status is critical for deciding intrapartum antibiotic prophylaxis. PCR results are qualitative (detected/not detected) and often include a cycle threshold (Ct) value and internal control to confirm sample integrity; however, PCR does not provide antibiotic susceptibility data, so positive results should be reviewed with an obstetrician who may order culture-based testing if sensitivity information is required.

• Streptococcus agalactiae (Group B Streptococcus) DNA Detection
