Bact. Vaginosis & Candida Panel
Test Overview
The Bacterial Vaginosis and Candida Panel is an advanced diagnostic test designed to detect bacterial imbalances and yeast infections that may cause vaginal discomfort. Utilizing cutting-edge molecular techniques, this test accurately identifies key bacterial pathogens and Candida species from a vaginal swab sample. By providing precise and reliable results, it helps healthcare providers diagnose infections effectively and recommend the most appropriate treatment for optimal vaginal health.
Test Types
- PCR Bacterial Vaginosis & Candida Panel: Detects bacterial and fungal DNA linked to vaginal infections.
- Vaginal pH Testing: Assesses pH imbalance, often elevated in BV.
- Wet Mount Microscopy: Identifies yeast cells, clue cells (BV), and trichomonads.
- Gram Stain: Evaluates bacterial composition and the presence of lactobacilli.
- Culture (Yeast or BV Bacteria): Identifies resistant or uncommon strains.
Test Results & Ranges
| Test Component: | Normal Range: | Abnormal (Indicates Infection): |
|---|---|---|
| Gardnerella vaginalis (BV-associated bacteria) | Not detected | Detected – Suggests Bacterial Vaginosis (BV) |
| Atopobium vaginae (BV-associated bacteria) | Not detected | Detected – Often present in persistent BV cases |
| Lactobacillus species (Normal Flora) | Detected | Low or Not Detected – Suggests BV |
| Mobiluncus species (BV-associated bacteria) | Not detected | Detected – Associated with BV |
| Mycoplasma hominis (BV-associated bacteria) | Not detected | Detected – Linked to BV |
| Ureaplasma species (BV-associated bacteria) | Not detected | Detected – Sometimes found in BV |
| Candida albicans (Yeast) | Not detected | Detected – Indicates vaginal yeast infection |
| Candida glabrata (Yeast, Non-albicans species) | Not detected | Detected – Can cause recurrent yeast infections |
| Candida tropicalis, Candida parapsilosis, Candida krusei | Not detected | Detected – Other fungal species causing candidiasis |
| Vaginal pH | 3.8 – 4.5 | >4.5 – Suggests BV |
| Clue Cells (Microscopy) | None | Present – Indicates BV |
| Yeast Cells (Microscopy) | None | Present – Suggests candidiasis |
Interpreting Abnormal Results:
-
Positive for BV-associated bacteria (Gardnerella, Atopobium, etc.): Suggests Bacterial Vaginosis (BV), a common vaginal infection caused by an imbalance of normal vaginal flora. Symptoms may be thin, grayish-white discharge, fishy odor, and vaginal discomfort. Possible treatments could be Metronidazole or Clindamycin.
-
Positive for Candida species (Yeast Infection): Indicates vaginal yeast infection (candidiasis). Symptoms may be thick, white “cottage cheese” discharge, itching, and irritation. Possible treatment could be Antifungal medications (Fluconazole, Clotrimazole).
-
Low Lactobacillus Species:A decrease in beneficial Lactobacillus bacteria is a key indicator of BV, as these bacteria help maintain a healthy vaginal pH.
-
Elevated pH (>4.5): Common in BV, as the infection disrupts the normal acidic vaginal environment. Yeast infections typically do NOT cause elevated pH (pH remains normal in Candida infections).
Expected Turnaround Time
- PCR Bacterial Vaginosis & Candida Panel: 24–48 hours
- Vaginal pH Testing: Immediate
- Microscopy (Wet Mount, Gram Stain): Same day
- Culture (Bacteria/Fungus): 2–5 days
Specimen Requirements
- Sample Type: Vaginal swab
- Container: Sterile collection tube or transport medium
Collection Instructions
- Do not use douches, vaginal creams, or medications for 24 hours before the test.
- Avoid intercourse for at least 24 hours prior to the test.
- Wash hands and use a sterile swab to collect a sample from the vaginal canal.
- Secure the sample in the provided container and deliver it to the lab as soon as possible.
Test Details
Clinical Use:
- Diagnosing Bacterial Vaginosis (BV): Identifies imbalances in vaginal bacteria.
- Detecting Yeast Infections (Candidiasis): Determines if Candida species are causing symptoms.
- Differentiating between BV and Yeast Infections: Helps guide appropriate treatment.
- Assessing Recurrent or Persistent Infections: Detects resistant or mixed infections.
Common Pathogens Detected:
-
Bacteria (BV-associated organisms): Gardnerella vaginalis, Atopobium vaginae, Mobiluncus species, Mycoplasma hominis, and Ureaplasma species.
-
Fungi (Candida species, Yeast):Candida albicans, Candida glabrata, Candida tropicalis, Candida parapsilosis, Candida krusei.
Limitations: False negatives, if the sample does not contain enough bacterial or fungal DNA, PCR may not detect an infection. PCR detects DNA from both live and dead organisms, so results should be correlated with clinical symptoms. Not a substitute for culture in resistant cases: Some Candida species may require further antifungal sensitivity testing.
Additional Notes
-
PCR testing is useful for patients with:
- Persistent or recurrent vaginal infections
- Unclear diagnosis between BV and yeast infection
- Non-responsive infections despite previous treatment
- Complicated cases in pregnancy or immunocompromised patients
-
If both BV and Candida are detected, treatment should address both infections simultaneously, as mixed infections can occur.
The Bacterial Vaginosis & Candida Panel (PCR Test) provides fast, accurate, and comprehensive detection of vaginal infections, ensuring proper diagnosis and targeted treatment for optimal patient care.
