GBS testing is typically performed during which gestational window?

Explanation:
Screening for GBS is done in the late third trimester, around 35–37 weeks of gestation. This timing captures the mother’s carriage status as close to delivery as possible, since GBS colonization can change over time. Testing earlier (first trimester or 28–32 weeks) might not reflect the reality at birth, and testing after birth cannot help prevent neonatal infection. If the test is positive, intrapartum antibiotic prophylaxis is given during labor to reduce the risk of early-onset GBS disease in the newborn; if negative, prophylaxis is not routinely given unless other risk factors are present.
