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.

Biomarker pairs for predicting preterm birth

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.
