title: Use of the nitrazine yellow swab test in the diagnosis of ruptured membranes.
abstract: Throat swabs impregnated with nitrazine yellow have been used to detect pH change in the vagina before and after amniotomy. The effect of infection on the test has been examined. A negative result is of use in excluding the diagnosis of ruptured membranes. A positive result is highly suggestive of the presence of amniotic fluid.
