Multimodality Screening for Lower Genital Tract Infections Between 18 and 24 Weeks of Pregnancy and its Efficacy in Predicting Spontaneous Preterm Delivery.

Background: Predicting spontaneous preterm birth (SPTB) during mid-trimester would be very useful. We used a multimodality screening approach mainly focusing on urogenital infections among unselected obstetric population between 18 and 24 weeks in a tertiary center.

Method: Diagnosis of lower genital tract infection (LGTI) was attempted among 228 pregnant women using several factors-symptom of vaginal discharge, characteristic appearance of discharge on speculum, point of care tests using Amsel's criteria and gram staining of vaginal swab.
