Alvernia Obstetric Screening Centre (AOSC) is located in Mount Alvernia Hospital. We are an ultrasound screening centre for pregnant women — and we’ve been operating in this hospital since July 2019, scanning patients from Mount Alvernia Hospital and other private hospitals. We have a team of experienced obstetric sonographers using high resolution ultrasound machines (i.e. GE E8), reporting with the Astraia ultrasound database software and producing quality comprehensive reports with clear suggestions if there are abnormalities. Clinical Pastoral Care department of the hospital works with AOSC to give compassionate care to support the parents if we do occasionally detect major fetal abnormalities.
