Abstract (en)
[origin: WO9417405A1] The present invention provides an assay that distinguishes those patients with impending imminent delivery with intact membranes from those in whom the membranes have ruptured. The method comprises obtaining a cervicovaginal secretion sample from a pregnant patient determined to be as at risk for imminent delivery by detection of a biochemical marker for imminent delivery in a cervicovaginal secretion sample from the patient and determining the level of IGFBP-1 in the sample. If the level of IGFBP-1 is elevated, the patient has rupture of membranes. If IGFBP-1 is not present, the patient has intact membranes. In a preferred embodiment, the method comprises obtaining a cervicovaginal secretion sample from a pregnant patient after about week 20 of gestation and determining the level of fetal fibronectin and IGFBP-1 in the sample. The presence of an elevated fibronectin level in the sample indicates an increased risk of imminent delivery. If the level of IGFBP-1 is elevated, the patient had rupture of membranes. If IGFBP-1 is not present, the patient has intact membranes. If IGFBP-1 is not present, the IGFBP-1 assay is preferably repeated. In those patients with an increased level of IGFBP-1, the test indicates that delivery cannot be delayed.
