A comparison was made of two brands of pH test paper and electronic instrumentation for measuring the pH of vaginal secretions. When the pH of vaginal secretions was greater than 4.5 (abnormal), there was no significant difference between the methods, showing that pH test paper is reliable for pH determination of vaginal secretions.
对两种用于测量阴道分泌物pH值的品牌pH试纸和电子仪器进行了比较。当阴道分泌物的pH值大于4.5（异常）时，两种方法之间没有显著差异，这表明pH试纸对于测定阴道分泌物的pH值是可靠的。
