Abstract:
1. A chromatographic specific binding assay strip device for the detection of amniotic fluid in vaginal secretions of pregnant women due to premature rupture of fetal membranes, said chromatographic specific binding assay strip device comprising: a) a non-permeable platform strip; b) a permeable membrane testing strip positioned on top of the non-permeable platform strip, said permeable membrane testing strip further comprising a test site for the detection of said premature rupture of fetal membranes, said site comprising a blend of at least: c) a sample receiving pad positioned on top of and at a proximal end of the non-permeable platform strip while in contact with a proximal end of the permeable membrane testing strip; d) a reservoir pad positioned on top of and at a distal end of the non-permeable membrane testing strip while in contact with a distal end of said permeable membrane test strip; and e) a conjugate pad positioned on top of or below said sample receiving pad, said conjugate pad comprising a permeable membrane containing a conjugate, said conjugate comprising a colorant attached to a vehicle which can attach to said biomarker.
