Receiver operator characteristic curve analysis of PCR/ESI-MS genome equivalents per PCR reaction well (GE/well) results for the identification of intra-amniotic inflammation (amniotic fluid IL-6 ≥ 2.6 ng/mL) among patients with detectable DNA of bacteria and/or viruses. Among patients with detectable DNA of bacteria or viruses using PCR/ESI-MS, a GE/well ≥17 had an area under the ROC curve of 0.93 (95% CI 0.83 – 1.0; p<0.001), a positive predictive value of 94.1% (16/17), and a negative predictive value of 84.6% (11/13) for the identification of intra-amniotic inflammation.
