Yeast Infection Tests
Reviewed
A yeast infection test helps find out whether you have a yeast infection (candidiasis). Yeast is a type of fungus that normally lives on your body but can overgrow and cause infection. The test is used to diagnose yeast infections on the skin, nails, mouth, vagina, or in invasive cases affecting the blood or organs.
Preparation and collection
No special preparation needed.
Understanding this test
Use the reference interval and units printed by the laboratory that performed the test. A result outside that interval is not a diagnosis by itself, and a result inside it does not rule out every condition. Your symptoms, history, medicines, timing, and related tests can change what the result means.
- At-home tests are screening only and may not confirm a diagnosis.
- Some yeast grows slowly; culture results may take weeks.
- Symptoms of vaginal yeast infection can overlap with sexually transmitted infections.
What to do next
Your healthcare provider will interpret results and recommend treatment if needed. Follow prescribed antifungal medicine as directed, even if symptoms improve before finishing the course.
