Antithrombin III (AT) Activity in Women with Severe Preeclampsia (PE) or Superimposed PE prior to 31weeks (AT3)


The purpose of this study is to see how the levels of Antithrombin (AT) change in women with preeclampsia. AT is an anticoagulant found in human blood. Preeclampsia is a condition that can develop around the 20th week of pregnancy, characterized by high blood pressure, protein in your urine, and water retention/swelling are the primary
symptoms. By studying the levels of AT in your blood during the 23rd to 31 weeks of your pregnancy, we may be able to better understand the effects that AT have in pregnancy complicated by preeclampsia.
