Itching around your vagina, a discharge that is different in color than usual, and especially a foul odor like fishy discharge can be very uncomfortable and distressing. You may feel embarrassed to talk to anyone about these symptoms. But the most important thing you need to know is that this is a common condition that many women experience. It can be caused by a common bacterial infection. So today, let's talk about a test that can accurately diagnose this condition.
What is Bacterial Vaginosis (BV)?
Don't be afraid of this name, it's a big disease. Let's understand this simply. A healthy vagina always has a large number of "good" bacteria and a small number of "bad" bacteria. Think of your vagina as a beautiful flower garden. In this garden, there are good flowers (good bacteria) that we want, and a few weeds that we don't want (bad bacteria). Usually, because there are so many good flowers, the weeds don't have a chance to spread too much. These two are in a good balance.
But sometimes, for some reason, this balance is lost, the good bacteria decrease, and the bad bacteria spread rapidly. Just like weeds in a garden grow out of control. That's what we call Bacterial Vaginosis (BV) . This is not a sexually transmitted disease, but it is common among sexually active women.
What are the symptoms that suggest BV?
If you have one or more of these symptoms, it could be BV. However, some women may have the condition without any symptoms.
| Symptom | A simple explanation |
|---|---|
| An unpleasant odor | A strong, foul-smelling odor, especially fishy, coming from the vagina. This odor may be worse after sex. |
| Change in vaginal discharge | Discharge that is different from usual, thin, gray, or white. |
| Itching and pain | Itching, burning, or pain in and around the vagina. |
| Burning during urination | A burning or painful sensation when urinating. |
The most important thing is not to ignore these symptoms. Never be shy about talking to your doctor about this. This is very important for your health.
How is BV tested?
When you see a doctor, they will ask about your symptoms and decide if you need to have a test to confirm whether you have BV. This test involves taking a small sample of your vaginal discharge. This sample is then tested in several ways.
How should you prepare before the test?
To get the most accurate results from this test, you should avoid these things for 24 hours before the test, as they can affect the test results.
- Douching: Do not douche or other liquids into the vagina for any reason. This can disrupt the natural bacterial balance in the vagina.
- Avoid having sex.
- Avoid using tampons.
- Vaginal medications: If you use any creams, gels, or pills for itching or other reasons, do not use them the day before the test.
What happens on the day of the test?
This is just like a regular pelvic exam. You have nothing to worry about. The doctor or nurse will explain everything to you.
1. First, you will be asked to remove your clothing below the waist. You will be given a cloth or paper to cover your body to protect your privacy.
2. You will then be asked to lie down on an examination table and place your legs on specially designed stirrups.
3. The doctor will slowly and carefully insert a medical instrument called a speculum into your vagina. A lubricant is used to make it easier to insert, so it won't be very painful. However, you may feel some pressure or discomfort. This instrument gently pushes the walls of the vagina apart, allowing you to see inside clearly.
4. Then, insert a long cotton swab into the vagina and gently scrape off a small amount of the discharge that has stained the vaginal wall.
5. The sample obtained is placed in a clean container and the speculum is removed.
6. Then you can get back dressed and go home. The whole process only takes a few minutes.
Methods of testing the sample obtained
The vaginal discharge sample obtained by the doctor is tested in the laboratory using several methods. These are the most commonly used methods.
| Test method | What is happening? |
|---|---|
| Wet Mount | A small amount of the fluid is mixed with a liquid, placed on a glass slide, and examined under a microscope. The main thing to look for is the presence of a special type of cell called "Clue Cells." If you have BV, the cells in the vaginal wall have become surrounded by bad bacteria, making them appear fuzzy and blurry. |
| Whiff Test | This is a very simple test. A few drops of a special chemical are added to a sample of vaginal discharge. If a strong fishy odor is produced, that is strong evidence that BV is present. |
| Vaginal pH Test | A healthy vagina has a pH between 3.8 and 4.5, which is slightly acidic. This acidity helps control the growth of bad bacteria. In a BV infection, the pH is higher than 4.5. Although this test alone cannot confirm BV, it is used in conjunction with other tests. |
| DNA Test (PCR Test) | This involves testing the genetic material of the bacteria in the stool sample. Although this is a very accurate method, it is not commonly used because it is more expensive than other methods. |
Can a urine test detect BV?
No. This is a question that many people ask. A urine test cannot detect a BV infection. A urine test can only detect Urinary Tract Infections (UTI). Since BV is an infection of the vagina, a vaginal swab sample is required.
What are the test results and what to do next?
You can usually get the test results (report) within a day or two to three days.
- If the result is Normal: This means you do not have a bacterial infection. In that case, your doctor may order further tests to see if there is another cause for your symptoms.
- If the result is Abnormal: It means you have a BV infection.
If the test confirms that you have BV, your doctor will prescribe antibiotics. These can be taken as pills or as creams, gels, or pessaries that are inserted into the vagina. The most important thing is to take the medication exactly for the number of days your doctor prescribes. Do not stop taking the medication just because your symptoms have gone away. Doing so may cause the infection to come back.
It's especially important to get treatment for BV infection if you're pregnant or planning to become pregnant. If left untreated, there's a risk of complications, such as premature birth.
Shall we also learn about home tests (Home Kits)?
You can now purchase home testing kits from pharmacies and online that can check your vaginal pH or detect a BV infection at home.
These involve taking a sample of vaginal discharge yourself and testing it. With a pH test kit, when you apply the sample to a special strip of paper, it changes color. You can match that color to the color chart that comes with the kit to get an idea of the pH level.
However, even if you use a home test like this, it is very important to see a doctor to confirm the results. Because you should not rely solely on the results of a home test to self-medicate. Only your doctor can provide an accurate diagnosis and the most appropriate treatment.
Take-Home Message
- An unpleasant odor, unusual discharge, or itching from the vagina can often be caused by Bacterial Vaginosis (BV). Don't be embarrassed or afraid of this.
- Don't ignore these symptoms, see your doctor as soon as possible.
- The BV test is a simple, painless test that can be done in a few minutes.
- If the test confirms an infection, take the prescribed antibiotics exactly as prescribed.
- Even if you use home test kits, you should definitely see a doctor to confirm the results and for proper treatment.
