Testing for premature rupture of the amniotic membrane (PROM) during pregnancy is typically done via a sterile speculum exam, combined with clinical suspicion and patient history. The presence of amniotic fluid pooling from the cervical os is often confirmed by nitrazine testing or ultrasound. While it allows for a confident diagnosis, in many cases, it is not a useful indicator in the 47% of PROM occurrences which present no obvious leakage. 1 In terms of accuracy, the current gold standard for PROM testing is a dye infusion administered via amniocenteses. However, because of the expense involved and the invasive nature of the procedure, it is rarely performed.
