The Original Vaginal pH Test Designed for Accurate & Comprehensive Results!
Box of 12
pHEM-ALERT® test measures vaginal pH, and is intended for use by women who have any of the following vaginal symptoms:
- Unpleasant Odor
- Unusual Discharge
- Each test securely packed in a procedure blister tray
- Convenient, unique, patented applicator “key” with attached pH paper
- Easy to read pH chart included with every test set
This test may help decide if these symptoms are caused by an infection that may require follow-up by your healthcare provider. This test is only intended for women who have normal menstrual periods (periodic vaginal bleeding) or who may currently be pregnant. If you are pregnant, always discuss your symptoms and the result of this test with your healthcare provider and NEVER treat yourself.
Recent findings by Gutman et al1 demonstrate that two positive criteria, vaginal pH and amines, yield high sensitivity and specificity in diagnosing bacterial vaginosis.
Results: The prevalence of bacterial vaginosis in our study population was 38.7%. Vaginal pH was the most sensitive of all the criteria, at 89%, and a positive amine odor was the individual criteria with the highest specificity at 93%. Similar specificity was seen with combinations of two criteria and Amsel’s criteria. Receiver operating characteristic curve analysis yielded a preferred pH and percentage of clue cells of 5.0 and 20% respectively. However, a pH of 4.5 or greater improves sensitivity with minimal loss of specificity.
Conclusion: The clinical criteria for diagnosing bacterial vaginosis can be simplified to 2 clinical criteria without loss of sensitivity and specificity.
