Final answer:
The Fern test is a better test for premature rupture of membranes (PROM) than nitrazine.
Step-by-step explanation:
Premature rupture of membranes (PROM) is a condition where the amniotic sac leaks fluid before 38 weeks of gestation. There are several tests that can be used to diagnose PROM. While nitrazine is commonly used, a better test is the Fern test. The Fern test involves examining a sample of amniotic fluid under a microscope to look for characteristic fern-like patterns that indicate the presence of amniotic fluid.
