  5. AmniSure ® is a non-invasive, one-step immunochromatographic assay which detects the placental alpha microglobulin-1 protein (PAMG-1) using specific monoclonal antibodies. AmniSure ® has been evaluated in more than 20 peer reviewed clinical studies. It has been found to have a sensitivity of 98.9% and specificity of 100% 1. How does it work
  6. negative AmniSure results and 16 false-positive AmniSure results were identified. The AmniSure test used independently had a sensitivity of 95.7%, specificity of 92.3%, positive predictive value of 84.9%, and negative predictive value of 98.0%. A rupture of membranes protocol combining AmniSure and clinical assessment had a sensitivity of 98.2%
  7. Amnisure does have a high false positive rate, noted to be 19-30% in patients who were later found to have intact membranes by clinical measures, including negative pooling, arborization, and nitrizine

Data were entered and analyzed using the Statistical package for Social Science (SPSS version 17). The sensitivity, specificity, positive and negative predictive values for both Amnisure test and clinical examination were then calculated separately. A comparison was done of the results of Amnisure examination if rupture of membranes had occurred within 12 or more than 12hours, and if the test was accompanied with clinical examination or not.
