Levels of Maternal Serum Angiogenic Factors in Third-Trimester Normal Pregnancies: Reference Ranges, Influence of Maternal and Pregnancy Factors and Fetoplacental Doppler Indices

Abstract

In normal pregnancies during the third trimester, serum PlGF decreases, sFlt-1 increases and sFlt-1/PlGF ratio increases with GA. Angiogenic factor levels needed no adjustment for factors such as smoking, body mass index, blood pressure or parity.
