Which screening methodology is considered most effective for preeclampsia?

The most effective screening methodology for preeclampsia is a combined screening approach. This method integrates both biochemical and biophysical markers to enhance the accuracy of identifying women who are at risk for developing preeclampsia during pregnancy.

A combined screening utilizes various factors, including maternal characteristics, medical history, and specific biomarkers, as well as assessments such as ultrasound to evaluate blood flow in the placenta. This multifaceted approach allows healthcare providers to create a more comprehensive risk profile for each patient. For instance, by measuring serum markers such as proteins associated with placental dysfunction along with ultrasound assessments, healthcare professionals can better gauge an individual woman's risk for preeclampsia.

Using a singular method, such as risk-based, biochemical-based, or biophysical-based screening alone, may not provide the same level of sensitivity and specificity. Relying solely on one type of assessment could lead to missed diagnoses or unnecessary anxiety for women who may be at lower risk. Therefore, the combined screening approach is favored for its overall effectiveness in detecting preeclampsia early, leading to timely interventions that can improve maternal and fetal outcomes.
