Evaluation of Phosphorylated Insulin like Growth Factor Binding Protein-1 and Sonographically Measured Cervical Length for Prediction of Preterm Birth in Threatened Preterm Labor: A Clinical Approach

Abstract

Background and Objectives: Measurement of cervical length using Transvaginal Sonography (TVS) is commonly used to identify those patients of threatened preterm labor who are likely to deliver. Biochemical markers in cervical secretions namely fetal fibronectin and Phosphorylated Insulin like Growth Factor Binding Protien-1 (phIGFBP-1) have also been used to improve predictability. This study evaluated bedside kit test for phIGFBP-1 and cervical length measurement by TVS, individually and in combination, for prediction of preterm birth in patients with threatened preterm labor.
