Clinical Grade MIS Device for Cervical Assessment to Predict Preterm Birth

During this phase, we will measure MIS in 100 women at high risk of PTB (Group 1) and 100 women with symptoms of PTB to confirm its predictive potential for PTB. To determine whether MIS assessment could prove a platform technique for other tests and treatments within existing antenatal care pathways for PTB, we will also assess vaginal swabs for fFN and measure cervical length (CL) by ultrasound.
