Comparison of placental α microglobulin-1 protein assay (Amnisure) with speculum examination for the diagnosis of premature preterm rupture of membranes (PPROM): a clinical evaluation.

In this study, we aimed to compare the clinical outcomes of Premature Preterm Rupture of Membranes (PPROM) cases diagnosed by classical speculum examination and by placental alpha microglobulin-1 protein (PAMG-1) assay. The medical records of all patients with singleton pregnancies that were diagnosed with PPROM were retrospectively reviewed. Singleton pregnancies with PPROM diagnosis that was confirmed either by direct visualisation of amniotic fluid leaking through the cervix or by placental alpha microglobulin-1 protein (PAMG-1) assay if no amniotic fluid leakage was documented were included in the study. Demographics, prenatal and postnatal characteristics were reviewed from the medical charts and were recorded. The study included 138 pregnancies with PPROM; 111 patients in clinical speculum examination group and 27 in PAMG-1 assay group. There were no significant differences in maternal and pregnancy characteristics between the clinical speculum examination and PAMG-1 assay groups. Foetal outcomes were comparable between clinical speculum examination and PAMG-1 assay groups. In the clinical speculum examination group, there were nine (8.1%) chorioamnionitis cases, however, there were no chorioamnionitis cases in the PAMG-1 assay group during the latency period (p = .21). Impact statement What is already known on this subject? Placental alpha microglobulin-1 protein assay uses immunochromatography method to detect trace amount of placental alpha microglobulin-1 protei...
