The APTIMA Trichomonas vaginalis Assay is an in vitro qualitative nucleic acid amplification test (NAAT) for the detection of ribosomal RNA (rRNA) from Trichomonas vaginalis to aid in the diagnosis of trichomoniasis using the PANTHER System. The assay may be used to test the following specimens from symptomatic or asymptomatic women: clinician-collected endocervical swabs, clinician-collected vaginal swabs, and specimens collected in PreservCyt Solution.

The ATV Assay with the modified TCR, referred to as ATV Assay (Version 2) in this submission is the subject of this premarket notification. The ATV Assay (Version 2) is similar to the ATV Assay originally cleared (ref: K102911), except for the formulation of the TCR. The TCR is a HEPES-buffered solution containing lithium salts and derivatized magnetic beads. A second target capture oligo was added to the TCR formulation in order to accommodate future specimen types. The TCR modification did not result in the change of assay technology. The ATV Assay (Version 2) uses Target Capture (TC), Transcription Mediated Amplification (TMA), and Hybridization Protection Assay (HPA) technologies to qualitatively detect ribosomal RNA (rRNA) from Trichomonas vaginalis. The overall assay design as well as the assay procedural steps remain unchanged from that previously described in the original 510(k) for the ATV Assay (K102911). The ATV Assay (Version 2) kit is comprised of 3 boxes: 1. Refrigerated Box Contains the Amplification Reagent, Enzyme Reagent, Probe Reagent and Target Capture Reagent-B 2. Room Temperature Box Contains Amplification Reconstitution Solution, Enzyme Reconstitution Solution, Probe Reconstitution Solution, Selection Reagent and Target Capture Reagent 3. Controls Box Contains the Negative and Positive Controls The ATV Assay (Version 2) on PANTHER would utilize three specimen collection kits. These collection kits were cleared for use with the originally cleared ATV Assay and other commercialized APTIMA Assays. 1. APTIMA Unisex Swab Specimen Collection Kit for Endocervical and Male Urethral Swab Specimens 2. APTIMA Vaginal Swab Specimen Collection Kit 3. APTIMA Specimen Transfer Kit Instrumentation The ATV Assay (Version 2) was validated using the PANTHER System, which was previously cleared in May 2012 (Ref: K111409).

The APTIMA COMBO 2 Assay is a target amplification nucleic acid probe test that utilizes target capture for the in vitro qualitative detection and differentiation of ribosomal RNA (rRNA) from Chlamydia trachomatis (CT) and/or Neisseria gonorrhoeae (GC) to aid in the diagnosis of chlamydial and/or gonococcal urogenital disease using the PANTHER System as specified. On the PANTHER System, the assay may be used to test the following specimens from symptomatic and asymptomatic individuals: clinician-collected endocervical, vaginal and male urethral swab specimens, clinician-collected gynecological specimens collected in the PreservCyt Solution, and patient-collected vaginal swab specimens.

The APTIMA Combo 2 Assay combines the technologies of target capture, TMA, and DKA. Specimens are collected and transferred into their respective specimen transport tubes. The transport solutions in these tubes release the rRNA targets and protect them from degradation during storage. When the APTIMA Combo 2 Assay is performed in the laboratory, the target rRNA molecules are isolated from specimens by use of capture oligomers via target capture that utilizes magnetic microparticles. The capture oligomers contain sequences complementary to specific regions of the target molecules as well as a string of deoxyadenosine residues. A separate capture oligomer is used for each target. During the hybridization step, the sequence specific regions of the capture oligomers bind to specific regions of the target molecules. The capture oligomer:target complex is then captured out of solution by decreasing the temperature of the reaction to room temperature. This temperature reduction allows hybridization to occur between the deoxyadenosine region on the capture oligomer and the poly-deoxythymidine molecules that are covalently attached to the magnetic particles. The microparticles, including the captured target molecules bound to them, are pulled to the side of the reaction vessel using magnets and the supernatant is aspirated. The particles are washed to remove residual specimen matrix that may contain amplification reaction inhibitors. After the target capture steps are completed, the specimens are ready for amplification. Target amplification assays are based on the ability of complementary oligonucleotide primers to specifically anneal and allow enzymatic amplification of the target nucleic acid strands. The APTIMA Combo 2 Assay replicates a specific region of the 23S rRNA from CT and a specific region of the 16S rRNA from GC via DNA intermediates. A unique set of primers is used for each target molecule. Detection of the rRNA amplification product sequences (amplicon) is achieved using nucleic acid hybridization. Single-stranded chemiluminescent DNA probes, which are complementary to a region of each target amplicon, are labeled with different acridinium ester molecules. The labeled DNA probes combine with amplicon to form stable RNA:DNA hybrids. The Selection Reagent differentiates hybridized from unhybridized probe, eliminating the generation of signal from unhybridized probe. During the detection step, light emitted from the labeled RNA:DNA hybrids is measured as photon signals in a luminometer, and are reported as Relative Light Units (RLU). In DKA, differences in the kinetic profiles of the CT and GC labeled probes allow for the differentiation of signal; kinetic profiles are derived from measurements of photon output during the detection read time. The chemiluminescent detection for CT signal has very rapid kinetics and has the "flasher" kinetic type. The chemiluminescent detection reaction for GC signal is relatively slower and has the "glower" kinetic type. Assay results are determined by a cut-off based on the total RLU and the kinetic curve type.
