Background and Aim Fetal hemoglobin (Hb) has been described as a new predictive biomarker for pre-eclampsia and has also been hypothesized to be a causative factor. Interestingly, the heme scavenger and antioxidant α-microglobulin increases in parallel with fetal Hb. The aim was to measure the level of fetal Hb in the serum of pregnant women with pre-eclampsia. Patients and methods This a prospective study that was conducted on 100 pregnant women selected from the Obstetrics and Gynecology Department of Al-Hussein University Hospital. Results There was a significant increase in fetal Hb in the patient group more than the control group. The fetal Hb shows a high sensitivity, specificity, and accuracy in prediction of pre-eclampsia and eclampsia. Conclusion Fetal Hb was significantly higher in patients with eclampisa and pre-eclampsia. Moreover, it can be used as a predictive marker for both eclampisa and pre-eclampsia.
