The AmnioTest™ is designed to assist in detecting rupture of the fetal membranes, based on the elevation of the pH in the upper vagina consistent with leakage of amniotic fluid. The sterile swab, impregnated with nitrazine yellow dye, offers a rapid, reliable, cost-effective and simple-to-use point-of-care test to aid in detecting amniotic fluid in patients with suspected PROM.
