How To Carry Out an At-home Yeast Infection Test

A healthy vagina has an acidic pH and a good balance of bacteria and yeast cells. But an imbalance of bacteria and yeast cells can alter the vaginal pH levels and lead to a vaginal yeast infection.

Also known as candidiasis or vaginal thrush, vaginal yeast infections are relatively common, and it’s estimated that they affect 3 out of 4 women at some point in their lifetime.

If you suspect you have a vaginal yeast infection, here’s our detailed guide on how to perform an at-home yeast infection test to determine whether you have an infection.

Symptoms of a Vaginal Yeast Infection

While intense itchiness and an uncomfortable burning sensation are telltale signs of a vaginal yeast infection, some other symptoms aren’t as obvious. Here are some other common signs of vaginal thrush:

  • Pain during sex
  • Pain during urination
  • Thick, whitish-yellow vaginal discharge
  • Vaginal swelling, redness, or soreness

If you experience any of these symptoms, performing a vaginal pH test (sometimes called a candida test) can allow you to determine whether you have a yeast infection.

How To Perform an At-home Vaginal pH Test

Vaginal pH Test Strip. Vaginal fluid is smeared on the test pad. The color of the test pad is then compared with a color key.

Follow these steps to perform an at home vaginal pH test:

  1. Wash your hands thoroughly and dry them before taking the test.
  2. Open the test kit and carefully remove the vaginal pH test strip and swab from their packaging. Place both on a flat, clean, dry surface, such as your bathroom countertop. Avoid touching the test strip’s test area or the swab tip, as doing so could affect the results.
  3. For easy sample collection, stand and place one foot on a raised surface, such as a toilet seat or another steady surface.
  4. Pick up the swab and hold one of its ends with one hand. With your other hand, spread apart the folds of skin around your vaginal opening (your labia).
  5. Gently insert the swab about five centimeters (about two inches) into your vagina and place it against your vaginal wall. Slowly rotate the swab and hold it against your vaginal wall for about five seconds to ensure it becomes moist.
  6. Slowly remove the swab from your vagina. To keep the sample clean, ensure the swab’s tip doesn’t touch anything else before proceeding with the next step.
  7. Smear the swab on the pH test strip’s test area several times until the color on the test area gradually starts changing.
  8. Compare the color on the test area to the color chart on the test kit. For best results, compare the colors after 30 seconds.
  9. Record your results.

Performing an at home yeast infection test is easy. Collect a sample of vaginal fluid and smear it on the vaginal pH test strip. The color of the reagent pad is then compared with the color key. The pH of the vaginal fluid provides clues about vaginal infections.

How To Interpret the Vaginal pH Test Results

The color on your vaginal pH test strip indicates your vaginal pH, and the color chart on the yeast infection test kit has a pH scale ranging from 3.8 to 7.

Ideally, your vaginal pH should range between 3.8 to 4.4, which is moderately acidic. If your vaginal pH is above 4.4 and you’re experiencing any of the symptoms mentioned above, you may have a vaginal yeast infection. Higher than normal vaginal pH is also linked to Bacterial Vaginosis (BV) and Trichomoniasis (Trich). Refer to the following table to understand your results.
