Prelabor rupture of membranes (PROM) remains a challenge in obstetrics with serious complications. Quantitative vaginal fluid creatinine concentration is a promising test for diagnosing PROM in resource-limiting settings. However, uncovered factors may affect the diagnostic power of this potential test. We aimed to investigate how clinical factors may affect this diagnostic power.
