How is Bacterial Vaginosis Diagnosed? Discover the Latest Testing Methods
Published: Jun 26, 2024
Diagnosing Bacterial Vaginosis (BV) accurately ensures proper treatment and management. Learn about the tests that can help diagnose BV effectively.
Clinical Laboratory Tests
Clinical lab tests are becoming more popular for diagnosing BV due to their high accuracy. These tests use advanced techniques like nucleic acid amplification tests (NAATs) to detect specific bacteria associated with BV. They are more reliable than traditional methods and can also test for other infections like yeast infections and trichomoniasis.
Point of Care Tests
Point of care tests can be done quickly in a doctor's office. These tests often involve checking the vaginal pH and conducting a whiff test to identify a fishy odor. While not as commonly used as lab tests, they can provide quick results in some cases. However, clinical evaluation is still necessary to rule out other conditions.
Amsel Criteria
The Amsel Criteria is a method used when microscopy is available. It involves checking for specific symptoms like a thin, grayish-white discharge, elevated vaginal pH, a positive whiff test, and the presence of clue cells under a microscope. When used by expert clinicians, the Amsel Criteria have high sensitivity and specificity for diagnosing BV.
