  • Patent number: 11987846
    Abstract: The disclosure provides a pair of isolated biomarkers selected from the group consisting of IBP4/SHBG, IBP4/PSG3, IBP4/LYAM1, IBP4/IGF2, CLUS/IBP3, CLUS/IGF2, CLUS/LYAM1, INHBC/PSG3, INHBC/IGF2, PSG2/LYAM1, PSG2/IGF2, PSG2/LYAM1, PEDF/PSG3, PEDF/SHBG, PEDF/LYAM1, CD14/LYAM1, and APOC3/LYAM1, wherein the pair of biomarkers exhibits a change in reversal value between pregnant females at risk for pre-term birth and term controls. Also provided is a method of determining probability for preterm birth in a pregnant female, the method comprising measuring in a biological sample obtained from the pregnant female a reversal value for at least one pair of biomarkers selected from the group consisting of IBP4/SHBG, IBP4/PSG3, IBP4/LYAM1, IBP4/IGF2, CLUS/IBP3, CLUS/IGF2, CLUS/LYAM1, INHBC/PSG3, INHBC/IGF2, PSG2/LYAM1, PSG2/IGF2, PSG2/LYAM1, PEDF/PSG3, PEDF/SHBG, PEDF/LYAM1, CD14/LYAM1, and APOC3/LYAM1 to determine the probability for preterm birth in the pregnant female.

  • Patent number: 11662351
    Abstract: Compositions and methods for predicting due date and time to birth for a pregnancy with significantly higher accuracy than current clinical methods. The compositions and methods for predicting due date and time to birth for a pregnancy can also identify those pregnancies that will deliver earlier than the due date derived from Last Menstrual Period (LMP) and/or obstetric ultrasonography (US) dating.

  • Publication number: 20140287948
    Abstract: The disclosure provides biomarker panels, methods and kits for determining the probability for preterm birth in a pregnant female. The present disclosure is based, in part, on the discovery that certain proteins and peptides in biological samples obtained from a pregnant female are differentially expressed in pregnant females that have an increased risk of developing in the future or presently suffering from preterm birth relative to matched controls. The present disclosure is further based, in part, on the unexepected discovery that panels combining one or more of these proteins and peptides can be utilized in methods of determining the probability for preterm birth in a pregnant female with relatively high sensitivity and specificity. These proteins and peptides disclosed herein serve as biomarkers for classifying test samples, predicting a probability of preterm birth, monitoring of progress of preterm birth in a pregnant female, either individually or in a panel of biomarkers.
