What This Test Measures

The test uses a probe to detect specific antigens (proteins) produced by *Candida* yeast. If these antigens are present, it suggests active infection. This method is qualitative, meaning it only tells you whether the yeast is likely present or not, not how severe it is.

How the Test Works

Your vaginal fluid is collected and analyzed for *Candida* antigens. The probe reacts if the yeast is present, giving a positive result. This is a rapid, at-the-point-of-care test often done in a clinic or doctor’s office.

When You Might Need This Test

Doctors may recommend this test if you have symptoms like unusual discharge, itching, or discomfort in the vaginal area, especially if you suspect a yeast infection. It’s also used to confirm or rule out *Candida* infections in other parts of the body.

What to Expect Before or After

No special preparation is needed. You may be asked to clean the area gently before the test. Results are usually available immediately after the probe is applied. If you get a positive result, your doctor may recommend treatment with antifungal medications.

Reference range

Negative (Candida species DNA not detected)N/A

Specimen: serum

Patient should avoid vaginal douching, sexual intercourse, and use of vaginal medications or creams for at least 24-48 hours prior to specimen collection. Menstrual bleeding may affect results; collection is ideally performed when patient is not actively menstruating.

Frequently asked questions

Why is this test important?
This test helps confirm whether a yeast infection caused by *Candida* is present, guiding treatment decisions. While symptoms like itching and discharge can suggest a yeast infection, this test provides a direct way to check for the fungus itself, ensuring accurate diagnosis and appropriate treatment.
What does a positive result mean?
A positive result means the test detected *Candida* antigens in your vaginal fluid, strongly suggesting a yeast infection. Your doctor will work with you to determine the best treatment, which may include antifungal medications.
Can this test be used for other infections?
No, this test specifically looks for *Candida* yeast. If you have symptoms of other infections (like bacterial vaginosis or sexually transmitted infections), your doctor may recommend different tests.
