Normal amniotic fluid volume changes throughout pregnancy. Thus, the rapid strip test based on PAMG-1 seems to be a more sensitive bedside test compared with the test based on IGFBP-1 for the detection of amniotic fluid.Brace RA, Wolf EJ. In all remaining 15 cases, the test based on PAMG-1 proved to be superior by detecting amniotic fluid at least at one descending concentration below the test based on IGFBP-1. In 5 cases, both test methods showed the same results. Immunoassay strip tests were then compared in their ability to detect remaining concentrations of amniotic fluid.

These samples were diluted with 0.9% saline solution in a dilution series down to concentrations of 1:320. Samples of amniotic fluid were taken in 20 pregnant women between 31 3/7 and 41 2/7 gestational weeks at elective cesarean section before delivery of the newborn.

Our objective was to compare two rapid strip tests for the detection of amniotic fluid, based on the detection of insulin-like growth factor-binding protein-1 (IGFBP-1) and of placental alpha-microglobulin-1 (PAMG-1).
