NO DRUG THERAPY IN PRIMARY CARE (REFERRAL & ADVICE) [1st line] Adult An abnormal antenatal screening finding requires immediate clinical triage based on the specific test affected. For abnormal glucose tolerance, initiate dietary advice and schedule antenatal monitoring; for positive infection screens, arrange targeted confirmatory testing and appropriate prophylaxis; for blood pressure or proteinuria abnormalities, evaluate urgently for preeclampsia. Correlate all abnormal screening results with obstetric ultrasound and refer promptly to an obstetrician. - Refer, with advice Peds Adult-only condition - paediatric section not applicable Source No dose - referral pathway, no medicine given in primary care Why An abnormal antenatal screening finding requires immediate clinical triage based on the specific test affected. For abnormal glucose tolerance, initiate dietary advice and schedule antenatal monitoring; for positive infection screens, arrange targeted confirmatory testing and appropriate prophylaxis; for blood pressure or proteinuria abnormalities, evaluate urgently for preeclampsia. Correlate all abnormal screening results with obstetric ultrasound and refer promptly to an obstetrician. Caution RED FLAG - Reduced fetal movement or fetal growth restriction: assess urgently and refer. An abnormal glucose tolerance test, a positive infection screen, or abnormal blood pressure or protein result needs prompt action specific to that finding. No medicine is prescribed for this in primary care - this entry is for recognition and referral. Anything given is decided by the service it is referred to. RED FLAG - Acute events such as evolving placental abruption and cord prolapse require prompt clinical evaluation and urgent delivery, as routine fetal surveillance is not predictive in these settings. Prices are indicative (dataset snapshot 2026-06); verify with the pharmacy. ``` --- Dawaa Reference is a reference for prescribers, not a medical device, and does not replace clinical judgement.
