   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™.

Test Procedure

  • Remove swab from protective sleeve (keep swab tip dry away from any liquid)
  • Insert swab into vagina ensuring that nitrazine tip gently comes in contact with the upper cervical area for about 15 seconds.
  • Carefully remove swab from vagina and immediately examine colour with AmnioTest™ colour card
