Test Code BVRNA Bacterial Vaginosis, Nucleic Acid Amplification, Vaginal


Specimen Required


Specimen Type: Vaginal

Supplies: Aptima Multitest Swab Collection Kit (T584)

Container/Tube: Aptima Multitest Swab

Specimen Volume: Swab

Collection Instructions:

1. Specimen must be collected using the Aptima Multitest Swab Collection Kit.

2. Insert swab (pink shaft) about 5 cm past introitus and rotate gently for 30 seconds.

3. Place swab into transport tube provided in collection kit. Snap off swab at score line so swab fits into closed tube.

4. Cap tube securely, and label tube with patient's entire name and collection date and time.

5. Maintain swab container between 2 and 30° C (refrigerate temperature is preferred) and transport within 30 days of collection. If longer storage is needed, store frozen between -20 and -70° C for up to 60 days.

Reference Values

Negative

Interpretation

Positive: Results should be interpreted alongside clinical presentation. Up to 40% of asymptomatic patients may test positive by this assay. Assay result is based on relative amounts of Lactobacillus (Lactobacillus gasseri, Lactobacillus crispatus, Lactobacillus jensenii), Gardnerella vaginalis, and Atopobium vaginae. Individual organisms are not reported.

 

Negative: A negative result does not exclude infection. Assay result is based on relative amounts of Lactobacillus (L gasseri, L crispatus, L jensenii), G vaginalis, and A vaginae.

 

Inconclusive: Repeat testing on a new sample is recommended if clinically indicated.

Method Description

The Aptima BV (bacterial vaginosis) assay is an in vitro nucleic acid amplification test that utilizes real time transcription-mediated amplification for detection and quantitation of ribosomal RNA from bacteria associated with BV, including Lactobacillus (Lactobacillus gasseri, Lactobacillus crispatus, Lactobacillus jensenii), Gardnerella vaginalis, and Atopobium vaginae. The Panther system detects and discriminates between four fluorescent signals corresponding to Lactobacillus group, Atopobium vaginae, Gardnerella vaginalis, and IC amplification products. Signal emergence times for each target organism are compared to calibration information to determine the BV Positive or Negative status of each sample.(Package Insert: Aptima BV Assay.
