Understanding Your Results

The BV Rapid Assay Test results should be interpreted in conjunction with the patient's clinical presentation, medical history, and other diagnostic criteria. The following guide provides a general framework for understanding your results:
📊

Negative

No bacterial sialidase enzyme activity detected in the vaginal discharge sample. This suggests that bacterial vaginosis is unlikely. However, if symptoms persist, further evaluation for other causes of vaginal discharge (such as yeast infection or trichomoniasis) may be warranted.

Action: Discuss results with your healthcare provider. If symptoms persist, additional testing may be recommended.

📊

Positive

Bacterial sialidase enzyme activity detected in the vaginal discharge sample. This is suggestive of bacterial vaginosis. Sialidase is produced by BV-associated anaerobic bacteria and is a reliable biomarker for the condition.

Action: Consult your healthcare provider for appropriate antibiotic treatment. Complete the full course of prescribed medication. Partner evaluation is generally not required for BV, but follow-up testing may be recommended.

📊

Equivocal / Borderline

Results that are borderline or uncertain may require repeat testing or correlation with Amsel's clinical criteria (vaginal pH > 4.5, positive whiff test, clue cells on microscopy, and characteristic discharge).

Action: Consult your healthcare provider for repeat testing or additional diagnostic workup.

⚠️ When to Consult a Doctor:

Consult a qualified gynecologist or healthcare provider if you experience persistent vaginal discharge with a fishy odor, unusual color or consistency of discharge, vaginal itching, burning, or pain during urination or intercourse. Pregnant women with BV symptoms should seek immediate medical attention due to the risk of preterm delivery and other pregnancy complications.

Limitations

  • ⚠This is a qualitative screening test and may not be 100% accurate in all cases
  • ⚠False positives can occur in the presence of other sialidase-producing organisms
  • ⚠False negatives may occur if sample collection is improper or if the patient has used interfering substances
  • ⚠Clinical correlation with Amsel's criteria or Nugent score is recommended for definitive diagnosis
  • ⚠This test does not identify specific bacterial species involved

Risks & Considerations

  • ●The test is non-invasive with virtually no risks or complications
  • ●Minor temporary discomfort may occur during swab collection
  • ●No bleeding or infection risk associated with the swab procedure

Interfering Factors

  • ●Use of vaginal creams, ointments, or lubricants within 48 hours before sample collection
  • ●Use of spermicides or feminine hygiene sprays within 48 hours prior to testing
  • ●Recent use of vaginal antibiotics or antifungal medications
  • ●Menstruation or recent douching may affect results
  • ●Presence of other vaginal infections may occasionally interfere with interpretation

ComparisonBacterial Vaginosis (BV) Rapid Assay TestThe wet mount examines vaginal discharge under a microscope for clue cells, yeast, or trichomonads. It requires laboratory equipment and trained personnel, while the BV Rapid Assay provides a quicker enzymatic result.The Nugent Score is considered the gold standard for BV diagnosis by grading bacterial morphotypes on a Gram-stained vaginal smear. It is more time-consuming and laboratory-dependent compared to the rapid assay.Amsel's criteria require at least 3 of 4 findings: thin homogeneous discharge, vaginal pH > 4.5, positive whiff test, and clue cells on microscopy. The BV Rapid Assay is a single-point enzymatic test that can supplement or streamline this process.Vaginal pH testing alone is not specific for BV as elevated pH can occur with other infections and conditions. The BV Rapid Assay offers higher specificity by detecting a BV-associated enzyme.

Frequently Asked Questions

What is Bacterial Vaginosis (BV)?
Bacterial Vaginosis (BV) is a common vaginal infection caused by an imbalance in the natural bacteria present in the vagina. When the normal protective Lactobacillus bacteria decrease and anaerobic bacteria such as Gardnerella vaginalis overgrow, it leads to BV. It is the most common cause of vaginal discharge in women of reproductive age and can cause symptoms including a fishy odor, grayish-white discharge, and vaginal discomfort.
What causes Bacterial Vaginosis?
BV is caused by an imbalance in the vaginal microbiome. Contributing factors include douching, new or multiple sexual partners, intrauterine device (IUD) use, smoking, and use of scented vaginal products. However, BV can also occur without any identifiable risk factor. It is not classified as a sexually transmitted infection, although sexual activity can influence the vaginal bacterial balance.
What is the BV Rapid Assay Test?
The BV Rapid Assay Test is a diagnostic test that detects the presence of bacterial sialidase enzyme in vaginal discharge. This enzyme is produced by the anaerobic bacteria associated with BV. The test uses a chromogenic enzyme method and provides a qualitative (positive or negative) result, often within the same day, making it a quick and reliable screening tool for bacterial vaginosis.
How much does the BV Rapid Assay Test cost in India?
The BV Rapid Assay Test costs INR 819 at DNA Labs India. This price includes test charges and free home sample collection when booked online. The same discounted rate is available across all major cities in India including Mumbai, Delhi, Bangalore, Hyderabad, Chennai, Kolkata, Pune, Ahmedabad, and many more.
What sample is required for the BV Rapid Assay Test?
The test requires a vaginal swab sample collected from the vaginal wall or posterior fornix. The swab is placed in a sterile screw-capped container and shipped refrigerated to the laboratory. You must avoid using vaginal creams, ointments, spermicides, lubricants, or feminine sprays for at least 48 hours before sample collection.
Is the BV Rapid Assay Test painful?
No, the BV Rapid Assay Test is not painful. The vaginal swab collection is a quick and minimally invasive procedure that typically causes little to no discomfort. It takes less than a minute to collect the sample, and you can resume normal activities immediately afterward.
How long does it take to get the results of the BV Rapid Assay Test?
Samples collected daily by 4:00 PM are processed the same day. Reports are typically available on the same day via your preferred delivery method including online portal, email, or WhatsApp. The rapid turnaround time allows for timely diagnosis and treatment initiation.
Can Bacterial Vaginosis go away on its own?
In some cases, mild BV may resolve on its own without treatment. However, it is not advisable to leave BV untreated as it can persist, recur, or lead to complications such as pelvic inflammatory disease (PID), increased susceptibility to sexually transmitted infections including HIV, and pregnancy complications such as preterm birth. It is recommended to consult a healthcare provider for proper diagnosis and treatment.
What happens if Bacterial Vaginosis is left untreated?
Untreated BV can lead to several complications including increased risk of acquiring sexually transmitted infections (such as HIV, chlamydia, and gonorrhea), pelvic inflammatory disease (PID), post-surgical infections after gynecological procedures, and adverse pregnancy outcomes including preterm delivery and low birth weight. Early diagnosis and treatment are important to prevent these complications.
Is Bacterial Vaginosis a sexually transmitted infection (STI)?
Bacterial Vaginosis is not classified as a sexually transmitted infection. However, it is more common in sexually active women and is associated with having new or multiple sexual partners. BV results from an imbalance in the vaginal microbiome rather than direct transmission of a specific pathogen. Male partner treatment is generally not recommended, and BV is not spread through casual contact.
Can I get Bacterial Vaginosis again after treatment?
Yes, BV can recur after treatment. Studies show that up to 50% of women experience a recurrence within 12 months of treatment. Recurrence may be due to incomplete treatment, re-infection, or persistent disruption of the vaginal microbiome. To reduce recurrence, complete the full course of prescribed antibiotics, avoid douching, use condoms consistently, and discuss preventive strategies with your healthcare provider.
How is Bacterial Vaginosis treated?
BV is typically treated with antibiotics such as metronidazole or clindamycin, available as oral tablets or vaginal gel/cream. Your healthcare provider will prescribe the most appropriate treatment based on your symptoms and medical history. It is essential to complete the entire course of antibiotics even if symptoms improve before finishing the medication. Avoid alcohol during metronidazole treatment as it can cause severe nausea and vomiting.
