Preterm birth is a major worldwide issue and presents a variety of complications. The World Health Organisation (WHO) estimates 15 million babies are born prematurely each year worldwide, of which approximately 1.1 million die and more than 10% of preterm new-borns are at risk of permanent physical disability, including cerebral palsy and hearing impairment. Diagnostic tools are essential because problems caused by preterm birth can be prevented or mitigated if diagnosed in time. However, the prevailing treatment, transvaginal ultrasound, has poor accuracy and is not accessible to all women. EveryBaby is a patented handheld and mobile device that provides a much more accurate and easier-to-use alternative to transvaginal ultrasound. The product uses pioneering patented technology involving a novel method of impedance spectroscopy to pick up on changes to the composition and structure of cervical tissue when a mother is nearing birth. A clinical trial involving 449 pregnant women demonstrated the diagnostic accuracy of the EveryBaby probe passes the UK National Institute for Health and Care Excellence (NICE) guidelines. EveryBaby is a safe and accurate alternative available at a fraction of the cost other diagnostic methods, making it especially transformational for low-income countries where the problem is often most acute. It can be used as a routine test for pregnant women to provide peace of mind and to alert clinicians if they need to take action to safe guard the health of the mother and foetus.
