USPSTF recommends routine preeclampsia screening throughout
Pre-eclampsia is not uncommon during pregnancy, with an estimated 2 percent to 8 percent of pregnancies affected worldwide.

The U.S. Preventive Services Task Force (USPSTF) revisited the evidence regarding screening for pre-eclampsia and on Sept. 27 posted a draft recommendation statement and draft evidence review on the topic. Based on that evidence, the group recommended screening pregnant women for pre-eclampsia throughout pregnancy using blood pressure measurements -- a "B" recommendation.

Since 1996, when the task force released its previous recommendation on this subject, the clinical definition and identification of pre-eclampsia have changed, but the screening message remains essentially the same. In that 1996 recommendation, the USPSTF suggested screening all pregnant women for pre-eclampsia using office-based blood pressure measurement during their first prenatal visit and periodically throughout the remainder of the pregnancy -- also a B recommendation.
