Serum IL 6 and umbilical artery Doppler indices in pre-eclamptic patients

Maternal serum IL 6 > 0.82 ng/dl can be implicated as an early laboratory diagnosis of mild pre-eclampsia. The significant correlation between maternal serum IL 6 levels and Doppler velocimetry supports both the immunologic and the systemic endothelial dysfunction theories of pre-eclampsia.
