Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Partosure® test + Premaquick® test

Arm Description

All patients will have the same 2 tests.

Outcomes

Primary Outcome Measures

The primary outcome measure will be the occurrence of a premature delivery within 7 days after patient's inclusion.

Secondary Outcome Measures

Collection of the occurrence of a premature delivery within 7 days of inclusion, then calculation of specificity, positive and negative predictive values.
Collection of the occurrence of a premature delivery on Day 2 and Day 14 following the inclusion, then calculation of the sensitivities, specificities, positive and negative predictive values.
Collection of the number of invalid results requiring restarting the Premaquick test.
Collection of premature deliveries at different times (2, 7 and 14 days after inclusion visit), then comparison of the sensitivities and specificities of the two tests at different times.
a new calculation algorithm to predict the risk of preterm delivery, based on the results observed in this study.

5. Study Description

Brief Summary
Threatened preterm labor (TPL) is defined by cervical changes and regular and painful uterine contractions occurring between 24 and 36 + 6 weeks of gestation that may or may not lead to premature labor and delivery. There is no reliable way to predict preterm delivery. The study's hypothesis is that the Premaquick® test can improve the prediction of preterm delivery. The investigators also want to compare this test with the Partosure® (Placental alpha microglobulin-1) test.

8. Arms, Groups, and Interventions

Arm Title
Partosure® test + Premaquick® test
Arm Type
Experimental
Arm Description
All patients will have the same 2 tests.
Intervention Type
Device
Intervention Name(s)
Premaquick®
Intervention Description
Vaginal secretions are collected prior to any vaginal or endovaginal ultrasound examination to avoid false positives, with the nylon swab provided with the test (placed in the posterior fornix of the vagina for 10 seconds).Then the samples are tested with the Premaquick test. Results are obtained in 10 minutes.
Intervention Type
Device
Intervention Name(s)
PARTOSURE®
Intervention Description
An immunochromatographic test wich determines the qualitative in vitro detection of placental alpha microglobulin-1 (PAMG-1) in cervico-vaginal secretions.
Primary Outcome Measure Information:
Title
The primary outcome measure will be the occurrence of a premature delivery within 7 days after patient's inclusion.
Time Frame
The outcome measure is assessed at visit 2 (day 7), 7 days after the inclusion visit.
Secondary Outcome Measure Information:
Title
Collection of the occurrence of a premature delivery within 7 days of inclusion, then calculation of specificity, positive and negative predictive values.
Time Frame
At visit 2, Day 7 (7 days after inclusion visit V0)
Title
Collection of the occurrence of a premature delivery on Day 2 and Day 14 following the inclusion, then calculation of the sensitivities, specificities, positive and negative predictive values.
Time Frame
At visit 1, Day 2 (2 days after inclusion visit ) and D14 (14 days after inclusion visit )
Title
Collection of the number of invalid results requiring restarting the Premaquick test.
Time Frame
At the Inclusion visit Visit 0 (Day 0)
Title
Collection of premature deliveries at different times (2, 7 and 14 days after inclusion visit), then comparison of the sensitivities and specificities of the two tests at different times.
Time Frame
At visit 1 (Day 2) - Visit 2 (Day 7) and after end of research visit (Day 14)
Title
