Intended Use
The BD ProbeTec™ Trichomonas vaginalis (TV) Q* Amplified DNA Assay, when tested with the BD Viper™ System in Extracted Mode, uses Strand Displacement Amplification technology for the direct, qualitative detection of Trichomonas vaginalis DNA in clinician-collected female endocervical swab specimens, patient-collected vaginal swab specimens (in a clinical setting), and female urine specimens. The assay is indicated for use with asymptomatic and symptomatic females to aid in the diagnosis of trichomoniasis.
Device Description
The BD ProbeTec Trichomonas vaginalis (TV) Q* Amplified DNA Assay (TVQ Assay) is based on the simultaneous amplification and detection of target DNA using amplification primers and fluorescently-labeled detector probes. The reagents for SDA are dried in two separate disposable microwells: the Priming Microwell contains the amplification primers, fluorescently-labeled detector probe, nucleotides and other reagents necessary for amplification, while the Amplification Microwell contains the two enzymes (a DNA polymerase and a restriction endonuclease) that are required for SDA. The BD Viper™ System pipettes a portion of the purified DNA solution from each Extraction Tube into a Priming Microwell to rehydrate the contents. After a brief incubation, the reaction mixture is transferred to a corresponding, prewarmed Amplification Microwell which is sealed to prevent contamination and then incubated in one of the two thermally-controlled fluorescent readers. The presence or absence of Trichomonas vaginalis DNA is determined by calculating the peak fluorescence (Maximum Relative Fluorescent Units (MaxRFU) over the course of the amplification process and by comparing this measurement to a predetermined threshold value. In addition to the fluorescent probe used to detect amplified TV target DNA, a second labeled oligonucleotide is incorporated in each reaction Control (EC) oligonucleotide is labeled with a different dye than that used for detection of the TV specific target and is used to confirm the validity of the extraction process. The EC is dried in the Extraction Tubes and is rehydrated upon addition of the specimen and extraction reagents. At the end of the extraction process, the EC fluorescence is monitored by the BD Viper System and an automated algorithm is applied to both the EC and target-specific signals to report results as positive, negative, or EC failure.

No
The device description details a DNA amplification and detection assay based on fluorescence measurements and a predetermined threshold value. While it mentions an "automated algorithm" for reporting results, this appears to be a simple comparison against a fixed threshold, not indicative of AI/ML. There are no mentions of AI, DNN, or ML in the document, nor is there a description of training or test sets for an AI/ML model.

No.
This device is an in vitro diagnostic (IVD) assay designed for the detection of Trichomonas vaginalis DNA to aid in the diagnosis of trichomoniasis, not for direct treatment or therapy.

Yes
The "Intended Use" section explicitly states that the assay "is indicated for use with asymptomatic and symptomatic females to aid in the diagnosis of trichomoniasis." This directly indicates its role in diagnosing a medical condition.

No

The device description clearly outlines the use of physical reagents (microwells containing primers, probes, nucleotides, enzymes) and a hardware system (BD Viper™ System) for amplification and detection. While software is involved in analyzing the fluorescent signals and reporting results, the core of the device is a combination of hardware and chemical components.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the assay is used for the "direct, qualitative detection of Trichomonas vaginalis DNA" in various female specimens to "aid in the diagnosis of trichomoniasis." This clearly indicates that the device is intended for use in vitro (outside the body) to examine specimens from the human body to provide information for diagnostic purposes.
  • Device Description: The description details the components of the assay (reagents, microwells, enzymes) and how it works to detect target DNA using amplification and fluorescence. This is consistent with the technology used in many IVD tests.
  • Specimen Types: The assay is designed to test "clinician-collected female endocervical swab specimens, patient-collected vaginal swab specimens, and female urine specimens." These are all types of human specimens commonly used in IVD testing.
  • Performance Studies: The document includes detailed information about clinical performance characteristics (sensitivity and specificity) and reproducibility studies, which are standard requirements for demonstrating the analytical and clinical validity of an IVD.
  • Predicate Device: The mention of a "Predicate Device(s)" (K102911; APTIMA Trichomonas vaginalis Assay) is a strong indicator that this device is being compared to an already cleared IVD, a common practice in the regulatory pathway for new IVDs.

All of these factors align with the definition and characteristics of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Clinical Performance Characteristics:
First void urine specimens, clinician-collected endocervical swab specimens, and self-collected (in a clinical setting) vaginal swab specimens were collected from 1,222 compliant female subjects attending family planning, OB/GYN, and sexually transmitted disease clinics at seven geographically diverse clinical sites in North America. Specimens were collected from subjects presenting with symptoms of trichomoniasis (symptomatic) or from subjects during routine visits to their healthcare provider (asymptomatic). Subjects were excluded from the data analysis due to collection site workflow, opting to withdraw from the study after initially consenting, transport/handling/storage errors, informed consent issues, subjects failing to meet the inclusion/exclusion criteria, collection errors, shipping errors, instrument errors, operating condition excursions or labeling errors. Therefore, the final data analysis included 735 compliant subjects for urine specimens, 832 compliant subjects for vaginal specimens, and 995 compliant subjects for endocervical specimens.

For each compliant subject, clinical specimens were collected in the following order: (1) a first void urine, (2) a patient-collected vaginal swab, (3) three clinician-collected vaginal swabs, and (4) an endocervical swab. The three clinician collected vaginal swabs were used for reference and discrepant testing. The first two of these were randomized, one swab was tested for the Wet Mount (reference method) and the other swab was used for the InPouch TV Culture (reference method). The third swab was used for testing using a commercially available NAAT. The aliquot of neat urine, the self-collected vaginal swab, and the endocervical swab were tested on the BD Viper System in extracted mode with the TVO assay.

All sensitivity and specificity calculations were based on the total number of BD ProbeTec TVQ Assay results for endocervical, vaginal, and urine specimens, as compared to a composite reference method. The initial instrument error rate during the clinical study was 0.1%, or 3 indeterminate results out of 2568 tests. The final error rate after repeat testing was performed on indeterminate results was 0.04%, or 1 indeterminate result out of 2568 tests.

Reproducibility:
Reproducibility of the BD Viper System using the BD ProbeTec TVQ Assay was evaluated at three test sites on one BD Viper System per site. Each site was provided with four identical reproducibility panels, each of which consisted of samples prepared using either Vaginal Matrix in O Swab Diluent or urine matrix. Each panel member was either left unspiked (0x), or was spiked with known amounts of TV organism (ATCC strain 30001) at 0.3x, 1x, and 3x LOD for each respective specimen matrix. Three replicates of each panel member were tested every day for five days on each BD Viper System.

In addition to the fluorescent probe used to detect amplified TV target DNA, a second labeled oligonucleotide is incorporated in each reaction Control (EC) oligonucleotide is labeled with a different dye than that used for detection of the TV specific target and is used to confirm the validity of the extraction process. The EC is dried in the Extraction Tubes and is rehydrated upon addition of the specimen and extraction reagents. At the end of the extraction process, the EC fluorescence is monitored by the BD Viper System and an automated algorithm is applied to both the EC and target-specific signals to report results as positive, negative, or EC failure.

Intended Use

The BD ProbeTec™ Trichomonas vaginalis (TV) Q* Amplified DNA Assay, when tested with the BD Viper™ System in Extracted Mode, uses Strand Displacement Amplification technology for the direct, qualitative detection of Trichomonas vaginalis DNA in clinician-collected female endocervical swab specimens, patient-collected vaginal swab specimens (in a clinical setting), and female urine specimens. The assay is indicated for use with asymptomatic and symptomatic females to aid in the diagnosis of trichomoniasis.

Summary and Principles of Operation

When used with the BD Viper System, the BD ProbeTec TV Q* Amplified DNA Assay involves automated extraction of DNA from clinical specimens through the chemical lysis of cells, followed by binding of DNA to para-magnetic particles, washing of the bound nucleic acid, and elution in an amplification-compatible buffer. When present, TV DNA is then detected by Strand Displacement Amplification (SDA) of the specific target sequence in the presence of a fluorescently-labeled detector probe.

Analytical Performance Characteristics

Limit of Detection (Analytical Sensitivity)

The Limit of Detection (LOD) for the TV Q* Assay on the BD Viper System was determined for two strains of T. vaginalis (one Metronidazole-sensitive and one Metronidazole-resistant) by diluting in specimen matrices (vaginal swab, endocervical swab, and urine) and in clean BD O* Swab Diluent to create an LOD panel consisting of six target levels of organism. For each strain and target level, twenty replicates of each panel member were tested on different BD Viper Systems for a total of 60 replicates. LOD was confirmed using 20 replicates at the estimated LOD for each matrix type. The LOD for the TV Q* Assay in clean BD Q* Swab Diluent was determined to be 54.5 and 55.5 trichomonads/mL for ATCC Strains 30001 and 50143. respectively. The LOD for urine and swab matrices are presented in Table 1. The TV Q* Assay on the BD Viper System in extracted mode could detect with ≥95% proportion positive four additional ATCC strains (30237, 50144, 30184, and 30185) in urine matrix and three ATCC strains (30185, 30237, and 50144) in vaginal swab specimen matrix at a concentration of 122,1 TV/mL. ·

Clinical Performance Characteristics

First void urine specimens, clinician-collected endocervical swab specimens, and self-collected (in a clinical setting) vaginal swab specimens were collected from 1,222 compliant female subjects attending family planning, OB/GYN, and sexually transmitted disease clinics at seven geographically diverse clinical sites in North America. Specimens were collected from subjects presenting with symptoms of trichomoniasis (symptomatic) or from subjects during routine visits to their healthcare provider (asymptomatic). Subjects were excluded from the data analysis due to collection site workflow, opting to withdraw from the study after initially consenting, transport/handling/storage errors, informed consent issues, subjects failing to meet the inclusion/exclusion criteria, collection errors, shipping errors, instrument errors, operating condition excursions or labeling errors. Therefore, the final data analysis included 735 compliant subjects for urine specimens. 832 compliant subjects for vaginal specimens, and 995 compliant subjects for endocervical specimens.

For each compliant subject, clinical specimens were collected in the following order: (1) a first void urine, (2) a patient-collected vaginal swab, (3) three clinician-collected vaginal swabs, and (4) an endocervical swab. The three clinician collected vaginal swabs were used for reference and discrepant testing. The first two of these were randomized, one swab was tested for the Wet Mount (reference method) and the other swab was used for the InPouch TV Culture (reference method). The third swab was used for testing using a commercially available NAAT. The aliquot of neat urine, the self-collected vaginal swab, and the endocervical swab were tested on the BD Viper System in extracted mode with the TVO assay.

All sensitivity and specificity calculations were based on the total number of BD ProbeTec TVQ Assay results for endocervical, vaginal, and urine specimens, as compared to a composite reference method. Sensitivity and specificity by specimen type (comparing the TVO Assay with the composite reference method) are presented in Table 4. The initial instrument error rate during the clinical study was 0.1%, or 3 indeterminate results out of 2568 tests. The final error rate after repeat testing was performed on indeterminate results was 0.04%. or 1 indeterminate result out of 2568 tests.

Reproducibility

Reproducibility of the BD Viper System using the BD ProbeTec TVQ Assay was evaluated at three test sites on one BD Viper System per site. Each site was provided with four identical reproducibility panels, each of which consisted of samples prepared using either Vaginal Matrix in O Swab Diluent or urine matrix, Each panel member was either left unspiked (0x), or was spiked with known amounts of TV organism (ATCC strain 30001) at 0.3x, 1x, and 3x LOD for each respective specimen matrix. Three replicates of each panel member were tested every day for five days on each BD Viper System. A summary of the reproducibility data for the TVQ Assay is summarized in Table 5.
