You can find several different pH testing kits designed for testing vaginal pH on Amazon.
These kits have two basic components: pH paper strips and a color chart with corresponding pH values.
Some kits may also include Q-tips, but most do not as Q-tips are a common household item.
To measure vaginal pH, insert a Q-tip into the vagina and hold it against the wall of your vagina for five seconds to allow it to absorb moisture. Withdraw the wet Q-tip and press it against the pH paper strip until it is fully wet.
Wait for a few minutes for the color on the pH paper strip to develop. This step may take up to five minutes, depending on the kit. Compare the color of your pH paper strip to the colors on the chart. Write down the number.
Note, you must compare the color while the paper strip is wet. After it becomes dry, the color changes and it may no longer be accurate.
If your pH is below 4.5, you may rule out BV as BV often has a higher pH. But you cannot rule out yeast infection or cytolytic vaginosis, which may have a lower pH than 4.5.
We recommend this Pelvana brand because it is easier to read. Other brands are cheaper but may be a waste of money because it is hard to separate the colors for pH 4.5 and pH 5.0.
Note: Applying a NeuEve suppository, like BV Clear, can maintain vaginal pH in the normal range for up to 3 days. If you are currently using NeuEve suppositories, you will need to wait at least 3 days after your last suppository before measuring vaginal pH.
