Maternal Serum Homocysteine Levels and Uterine Artery Pulsatility Indices in Preterm Labor

February 14, 2018 updated by: Ahmed Walid Anwar Murad, Benha University

Maternal Serum Homocysteine Levels and Uterine Artery Pulsatility Index as Predictors of Spontaneous Preterm Labor

Study included all pregnant women admitted with threatened preterm labor during the study period. All participants underwent estimation of maternal serum homocysteine level and assessment of uterine artery Doppler indices.

Diagnostic test: Maternal serum homocysteine estimation
Term group
Included pregnant females delivered after completed 37 weeks of gestation. All participants underwent assessment of uterine artery Doppler indices and maternal serum homocysteine estimation
Diagnostic test: Uterine artery doppler
Uterine artery Doppler pulsatility indices
Diagnostic test: Maternal serum homocysteine estimation

What is the study measuring?
