Brief summary
To calculate sensitivity (SN), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) of PartoSure TTD test in predicting delivery within 7 or 14 days from testing and to compare it with cervical length (CL) measurement by transvaginal ultrasound (15 mm cut-off)
Detailed description
* This trial is a prospective observational study. * Pregnancies after ART between 20 0/7 and 36 6/7 weeks with symptoms of preterm labor, clinically intact membranes, cervical dilatation of ≤ 2 cm will be invited to participate to the study. Signed consent form is required to be able to participate to the study. * PartoSure and CL will be performed on all patients and the test-to-spontaneous-delivery interval will be calculated. * Trial Population:Pregnancies after ART between 20 0/7 and 36 6/7 weeks with symptoms of preterm labor are hospitalized at My Duc hospital from October 2015 to April 2016. The sample size for this trial of 100 subjects.
Interventions
PartoSure TTD test and CL will be performed on all patients and the test-to-spontaneous-delivery interval will be calculated.

Exclusion criteria
To be eligible for enrollment in this study each subject must not meet any of the following criteria: * Vaginal bleeding * Overt rupture of the fetal membranes as indicated by visualized leakage of fluid from the cervix * Placenta previa * Cervical cerclage in place * Received tocolytic medications for treatment of threatened preterm delivery prior to collection of the cervicovaginal specimens or CL measurement. * Digital exam prior to specimen collection. * A symptom not associated with idiopathic threatened preterm delivery (e.g trauma) * Enrollment in a tocolytic study.
