Hemolysis, Elevated Liver Enzymes, and Low Platelet Count (HELLP) Syndrome as a Complication of Preeclampsia in Pregnant Women Increases the Amount of Cell-free Fetal and Maternal DNA in Maternal Plasma and Serum

Abstract
Fetal DNA in plasma and serum of pregnant women has been reported to be significantly increased in preeclampsia (1)(2). This increase may even precede clinical diagnosis (3). We hypothesized that subsequent development of hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome will further increase fetal DNA in maternal plasma and serum. In addition, total cell-free DNA may be increased in plasma as a result of tissue destruction, which generally occurs in HELLP syndrome.
