4 weeks : If group strep is found during the pregnancy at any time (like a urine culture) then that patient will be treated when in labor. The culture is reliable for 4 weeks. Testing at 35/36 weeks will cover for those delivering in that time frame. Gbs is passed to baby when passing though the vaginal therefore treating while the patient is in labor is correct.
