Intended Use

The BD MAX Vaginal Panel performed on the BD MAX System is an automated qualitative in vitro diagnostic test for the direction of DNA targets from bacteria associated with bacterial vaginosis (qualitative results reported based on detection and quantitation of targeted organism markers), Candida species associated with vulvovaginal candidiasis, and Trichomonas vaginalis from vaginal swabs in patients who are symptomatic for vaginitis/vaginosis. The test utilizes real-time polymerase chain reaction (PCR) for the amplification of specific DNA targets and utilizes fluorogenic target-specific hybridization probes to detect and differentiate DNA from: . Bacterial vaginosis markers (Individual markers not reported) Lactobacillus spp. (L. crispatus and L. jensenii) Gardnerella vaginalis Atopobium vaginae Bacterial Vaginosis Associated Bacteria-2 (BVAB-2) Megasphaera-1 . Candida spp. (C. albicans, C. tropicalis, C. parapsilosis, C. dubliniensis) . Candida glabrata . Candida krusei . Trichomonas vaginalis The BD MAX Vaginal Panel is intended to aid in the diagnosis of vaginal infections in women with a clinical presentation consistent with bacterial vaginosis, vulvovaginal candidiasis and trichomoniasis.

Device Story

BD MAX Vaginal Panel is an automated in vitro diagnostic test performed on the BD MAX System; utilizes real-time PCR to detect DNA from specific bacteria, yeast, and parasites associated with vaginitis/vaginosis. Input: vaginal swab specimens in BD MAX UVE Sample Buffer Tubes. Process: automated sample preparation (lysis, DNA extraction/concentration, reagent rehydration, PCR amplification, detection via fluorogenic hybridization probes). Output: qualitative results for vaginitis analytes and bacterial vaginosis markers. Used in clinical laboratories; operated by trained personnel. Software automatically interprets amplification signals to provide POS, NEG, or UNR results. Modification (ADF version 3.0) improves assay tolerance and reduces non-reportable result rates while maintaining clinical performance.

Clinical Evidence

No clinical data provided in this summary; substantial equivalence is supported by the predicate device and performance standards.

Technological Characteristics

Nucleic acid-based test using real-time PCR; automated on BD MAX System. Components: microfluidic cartridges, master mixes, unitized reagent strips, extraction reagents. Detection via hydrolysis probes with fluorescent reporter dyes and quenchers. Software-controlled automated interpretation of results. Sample Processing Control (SPC) monitors extraction, amplification, and inhibition.

Indications for Use

Indicated for symptomatic women with clinical presentation of vaginitis/vaginosis to aid in diagnosis of bacterial vaginosis, vulvovaginal candidiasis, and trichomoniasis using vaginal swab specimens.

The instrument automates sample preparation including target lysis, DNA extraction and concentration, reagent rehydration, target nucleic acid amplification and detection using real-time PCR. The assay includes a Sample Processing Control (SPC) that is present in the Extraction Tube. The SPC monitors DNA extraction steps, thermal cycling steps, reagent integrity and the presence of inhibitory substances. The BD MAX System software automatically interprets test results. For the BD MAX Vaginal Panel, a test result may be called as POS, NEG or UNR (Unresolved) based on the {4}------------------------------------------------ amplification status of the targets and of the Sample Processing Control. IND (Indeterminate) or INC (Incomplete) results are due to BD MAX System failure. # Test Principle The BD MAX Vaginal Panel is designed for use with the BD MAX™ UVE Specimen Collection kit. Samples are transported to the testing laboratory in BD MAX UVE Sample Buffer Tubes (SBT). The Sample Buffer Tubes, are vortexed to release cells from the buffer. The Sample Buffer Tubes, Unitized Reagent Strips and PCR Cartridges are loaded on the BD MAX System. No further operator intervention is necessary and the following automated procedures occur. A combination of lytic and extraction reagents are used to perform cell lysis and DNA extraction. Nucleic acids released from the target organisms are captured on magnetic affinity beads. The beads, together with the bound nucleic acids, are washed and the nucleic acids are eluted by a combination of heat and pH. Eluted DNA is neutralized and transferred to the Master Mix Tubes to rehydrate the PCR reagents. After reconstitution, the BD MAX System dispenses a fixed volume of PCR-ready solution containing extracted nucleic acids into the PCR Cartridge. Microvalves in the cartridge are sealed by the system prior to initiating PCR in order to contain the amplification mixture and thus prevent evaporation and contamination. The amplified DNA targets are detected using hydrolysis probes, labeled at one end with a fluorescent reporter dye (fluorophore), and at the other end, with a quencher moiety. Probes labeled with different fluorophores are used to detect the target analytes in different optical channels of the BD MAX System. When the probes are in their native state, the fluorescence of the fluorophore is quenched due to its proximity to the quencher. However, in the presence of target DNA, the probes hybridize to their complementary sequences and are hydrolyzed by the 5'-3' exonuclease activity of the DNA polymerase as it synthesizes the nascent strand along the DNA template. As a result, the fluorophores are separated from the quencher molecules and fluorescence is emitted. The amount of fluorescence detected in the optical channels used for the BD MAX Vaginal Panel is directly proportional to the quantity of the corresponding probe that is hydrolyzed. The BD MAX System monitors these signals at each cycle of the PCR and interprets the data at the reaction to provide qualitative test results for each vaginitis analyte as well as qualitative results for bacterial vaginosis based on detection and quantitation of targeted bacterial vaginosis markers. | Items | BD MAX Vaginal Panel<br>(modified) | BD MAX Vaginal Panel<br>(DEN160001) | |--------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|-------------------------------------| | Regulation | 866.3975 | | | Product Code | PQA | | | Device Class | II | | | Intended Use | The BD MAX Vaginal Panel performed on the BD MAX System is<br>an automated qualitative in vitro diagnostic test for the direct<br>detection of DNA targets from bacteria associated with bacterial<br>vaginosis (qualitative results reported based on detection and<br>quantitation of targeted organism markers), Candida species<br>associated with vulvovaginal candidiasis, and Trichomonas<br>vaginalis from vaginal swabs in patients who are symptomatic for<br>vaginitis/vaginosis.
