AmnioTest™ is a qualitative, pH-based, swab screening system intended as an aid in detecting rupture of amniotic membrane in pregnant women.
- Detect rupture of amniotic membrane in pregnant women
- Determine the presence of amniotic fluid
- Swab absorbs fluid associated with the tissue and the dye develops a colour which correlates with the pH of the absorbed fluid
Rupture of the amniotic membrane can result in small volumes of amniotic fluid leaking into the upper vagina
A swab impregnated with nitrazine yellow dye is brought into contact with the upper vagina. The swab absorbs fluid associated with the tissue and the dye develops a colour which correlates with the pH of the absorbed fluid over the range pH 5.0 to pH 7.5. Amniotic fluid has a neutral pH while the pH of the upper vagina is normally acidic. A pH of 6.5 or higher in the upper vagina is consistent with leakage of amniotic fluid.
The presence of amniotic fluid tends to elevate the pH of the upper vagina. Detection of this pH increase using a pH indicator dye has been shown to assist in determining the presence of amniotic fluid.
