What does a whiff test test for?

What does a whiff test test for?

A whiff test is performed by adding several drops of 10% potassium hydroxide to a sample of vaginal discharge. A strong fishy odor is indicative of a positive test result. Such a result may suggest either trichomoniasis or bacterial vaginosis.

What does a positive amine test mean?

AMINE (WHIFF) TEST RESULT: The result should be reported as follows: Positive: The presence of a fishy odor following addition of KOH to the vaginal sample. Negative: The absence of a fishy odor following addition of KOH to the vaginal sample.

What tests are helpful in diagnosing the suspected vaginal candida infection?

If a vaginal yeast infection is suspected, your health care provider will perform a pelvic exam and take a sample of the discharge from your vagina. If thrush is suspected, your health care provider will look at the infected area in the mouth and may also take a small scraping to examine under the microscope.

Does BV cause high WBC?

We demonstrated that in 296 non-pregnant women with BV, elevated vaginal WBC counts (>5 WBCs per ×400) were associated with VVC, trichomoniasis, chlamydia, or gonorrhoea.

What pH indicates a yeast infection?

A pH above 4.5 suggests infections such as bacterial vaginosis or trichomoniasis (pH 5-6) and helps to exclude vulvovaginal candidiasis (pH 4-4.5).

Can you get a false negative BV test?

2 At-home tests look for byproducts of BV infection, but not the presence of the bacteria themselves, which means that you could get a false-negative result. If you have symptoms of BV, be sure to get tested by your nurse or healthcare provider or make an appointment at a sexual health clinic.

What is vaginal pH?

‌The vagina’s pH level is about 3.8 to 4.5, which means it’s on the acidic side. Its acidity slightly decreases as you get older, with its pH level rising closer to 5. Your vagina naturally is home to different types of healthy, acid-producing bacteria.

How accurate is a BV test?

Conclusion. Compared to a DNA probe standard, clinical diagnosis is 81-85% sensitive and 70- 99% specific for bacterial vaginosis, candida vaginitis, and trichomoniasis.

How do they test you for BV?

Your doctor may examine the vaginal secretions under a microscope, looking for “clue cells,” vaginal cells covered with bacteria that are a sign of bacterial vaginosis. Test your vaginal pH. Your doctor may check the acidity of your vagina by placing a pH test strip in your vagina.

What do amides smell like?

Most amides are colorless and odorless, and the lighter ones are soluble in water. Because they are polar molecules, amides have comparatively high boiling points and melting points. Amides are synthesized from carboxylic acids and NH 3 or amines.

What is the result of the amine (whiff) test?

AMINE (WHIFF) TEST RESULT: The result should be reported as follows: Positive: The presence of a fishy odor following addition of KOH to the vaginal sample. Negative: The absence of a fishy odor following addition of KOH to the vaginal sample.

How was the whiff test performed in the screening study?

The whiff test was performed by adding drops of the KOH solution directly on the speculum. In most cases, the whiff test was performed by the staff nurse assisting in the examination room. In the second phase of the screening study (cut-off line at 275 participants), BV diagnosis was based on the QuickVue Advanced® pH and Amines test.

How do you test for volatile amines in a vaginal sample?

Apply a portion of the undiluted vaginal material or one drop of the saline suspension to the surface of a clean glass slide. Add one drop of 10% KOH directly to the vaginal sample. Holding the slide gently fan the vapor layer (whiff) above the surface of the slide and asses for the presence of volatile amines which have a fishy odor.

How do you do a whiff test with a pH stick?

The pH stick was dipped in the vaginal fluid at the edge of the speculum. The whiff test was performed by adding drops of the KOH solution directly on the speculum. In most cases, the whiff test was performed by the staff nurse assisting in the examination room.
