The AmnioTest™ is designed to assist in the detection of rupture of the fetal membranes, based on 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 the detection of amniotic fluid in patients with suspected PROM.

   How Does AmnioTest™ Work?   

The pH of the vagina is normally acidic. Rupture of fetal membranes can result in small amounts of amniotic fluid leaking into the upper vagina. Amniotic fluid has a neutral pH.  Thus, the presence of amniotic fluid elevates the pH of the upper vagina.   AmnioTest™ is a sterile swab impregnated with nitrazine yellow dye that when brought into contact with the upper vagina will absorb fluid and develops a colour to correlate with the pH of the absorbed fluid ranging from pH 5.0 to pH 7.5.  A possible ruptured membrane is indicated if the swab has a pH of 6.5 to pH 7.5 turning the swab dark green to navy blue. A colour interpretation card is included with each box of AmnioTest™.
