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.
用浸有硝嗪黄的咽拭子检测羊膜破裂前后阴道内的pH变化。已对感染对该检测的影响进行了研究。阴性结果有助于排除胎膜破裂的诊断。阳性结果强烈提示羊水的存在。
