What is a vaginal pH test?
A vaginal pH test measures the acidity of the vaginal fluid on a scale of 1–14, with lower readings indicating greater acidity.

People who experience vaginal symptoms may use a vaginal pH test to help determine whether they have a bacterial or yeast infection.
bacterial
yeast infection
According to a 2021 study, the microbial ecosystem in the vagina is dynamic and can have varying pH levels. When this ecosystem is performing typically, the pH is acidic and ranges from around 3.8 to 5.
2021 study
The health of this ecosystem generally tends to depend on its most common microbiome, the Lactobacilli species. This produces an acidic environment that can protect the body from infections.
When these species decline, the vagina becomes more alkaline and less acidic. This leads to an imbalance, increasing the buildup of bacteria and resulting in vaginitis and other vaginal issues. Vaginal pH can also change the appearance of vaginal fluid and discharge.

Take out the swab, making sure not to touch the testing side.
Apply the test side to the pH paper.
Look for color changes on the pH paper.
Compare the color with the test kit’s chart.
Read the vaginal pH value that matches the color on the chart.

When to contact a doctor
A person should contact their doctor if an at-home test shows that their vaginal pH levels are outside the typical range. A doctor will offer additional tests to determine the cause and prescribe appropriate treatments as necessary.
According to the Food and Drug Administration (FDA), at-home vaginal pH testing kits are comparable to those a doctor would use. Nonetheless, a person who receives a vaginal pH result outside the typical range should make a follow-up appointment with their doctor.

An at-home vaginal pH test cannot say definitively if a person has an infection or what kind of infection that may be. A doctor can determine what type of infection a person has, if any.
It is also important to note that a vaginal pH test result that is within the typical range does not necessarily indicate the absence of a vaginal infection. Certain infections do not result in abnormal vaginal pH levels. Anyone who receives such a result and continues to experience symptoms should contact their doctor for a diagnosis and appropriate treatment.

It does not provide a diagnosis. If a person believes they may have a condition that changes the acidity of their vaginal pH, they should contact a healthcare professional for more advice.
Summary
A healthy vagina contains a balanced mix of bacteria and has a slightly acidic pH. Various factors can throw off the bacterial balance, including bacterial and yeast infections. These infections may cause a range of symptoms, including an unusual discharge, unpleasant odor, and irritation of the vulva or vagina.
A person may choose to take a vaginal pH test if they experience persistent or recurrent vaginal symptoms. The test involves placing a swab against the wall of the vagina. The swab contains a piece of pH paper that changes color to indicate the vaginal pH.
If the results are outside the typical range, a person should consult their doctor for a diagnosis and appropriate treatment. People should also speak with their doctor if their pH value is within the typical range, but they continue to experience symptoms.
