The cost of pre-eclampsia risk assessment varies depending on the medical institution where the pregnant woman visits, the region, and the specific items to be examined, and usually costs $400 to $1,000. Pre-eclampsia risk assessment refers to the comprehensive assessment of pre-eclampsia medical scales based on the evaluation of risk factors of pregnant women, combined with serum markers such as placental growth factor, pregnancy-related plasma proteins, etc., as well as the mean arterial pressure and uterine artery flow index of pregnant women. The cost usually ranges from $400 to $1,000, depending on the medical institution visited, the region, and the specific items examined. Pregnant women are at increased risk of developing preeclampsia if they have high risk factors, such as advanced age, obesity, history of preeclampsia and family history of preeclampsia (especially first-degree relatives such as mothers, sisters, etc.), or if they are suffering from chronic hypertension, severe diabetes mellitus, renal disease, or rheumatologic immune disease. Pre-eclampsia risk assessment can be helpful in predicting pre-eclampsia. Pre-eclampsia risk assessment requires a comprehensive assessment based on individual circumstances and reasonable testing under the guidance of a physician.
