T2Candida® 1.1 Panel and T2Dx® Instrument is a qualitative T2 Magnetic Resonance (T2MR®) assy for the direct detection of Candida species in K₂EDTA human whole blood specimens from patients with symptoms of, or medical conditions predisposing the patient to, invasive fungal infections. The T2Candida 1.1 Panel identifies five species of Candida and categorizes them into the following three species groups: - 1. Candida albicans and/or Candida tropicalis - 2. Candida parapsilosis - Candida glabrata and/or Candida krusei 3. The T2Candida 1.1 Panel does not distinguish between C. albicans and C. tropicalis. The T2Candida 1.1 Panel does not distinguish between C. glabrata and C. krusei. The T2Candida 1.1 Panel is indicated for the presumptive diagnosis of candidemia. The T2Candida 1.1 Panel is performed independent of blood culture. Concomitant blood cultures are necessary to recover organisms for susceptibility testing or further identification. The T2Candida positive and negative External Controls (T2Candida QCheck Positive Kit and the T2Dx QCheck Negative Kit) are intended to be used as quality control samples with the T2Candida 1.1 Panel when run on the T2Dx Instrument. These controls are not intended for use with other assays or systems.

The T2Candida 1.1 Panel and T2Dx Instrument is comprised of the T2Candida 1.1 Panel performed on the T2Dx Instrument. The T2Candida 1.1 Panel is a qualitative molecular diagnostic assay that employs a whole blood compatible PCR amplification followed by T2 magnetic resonance (T2MR) detection. The T2Candida 1.1 Panel is performed on the T2Dx Instrument which executes all steps after specimen loading. A K₂EDTA whole blood specimen is loaded onto the T2Candida 1.1 Sample Inlet, which is then placed on the T2Candida 1.1 Cartridge along with the T2Candida 1.1 Reagent Tray. The Reagent Tray contains the internal control, amplification reagent, enzyme and the probe-coupled superparamagnetic particles for each Candida target. Two milliliters of the blood specimen is transferred to the T2Dx Instrument where lysis of the red blood cells, concentration and lysis of the Candida cells and amplification of the Candida DNA takes place. Amplification products are detected by T2MR detection using species-specific probes which are attached to the superparamagnetic particles. The assay identifies Candida albicans and/or Candida tropicalis, Candida parapsilosis, and Candida glabrata and/or Candida krusei. The test does not distinguish between C. albicans and C. tropicalis. The test does not distinguish between C. glabrata and C. krusei

The T2Bacteria Panel run on the T2Dx Instrument is a qualitative T2 Magnetic Resonance (T2MR) test for the direct detection of bacterial species in K2EDTA human whole blood specimens with suspected bacteremia. The T2Bacteria Panel identifies six species of bacter baumannii, Enterococus faccium, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Staphylococcus aureus. The T2Bacteria Panel is indicated as an aid in the diagnosis of bacteremia and results should be used in conjunction with other clinical and laboratory data. Concomitant blood cultures are necessary to recover organisms for susceptibility testing or further identification and for organisms not detected by the T2Bacteria Panel. Results from the T2Bacteria Panel are not intended to be used as for diagnosis, treatment, or other patient management decisions in patients with suspected bacteremia.

The T2Bacteria Panel detects and identifies six bacterial target species directly from whole blood specimens and independent of blood culture using nucleic acid amplification and proprietary T2MR detection technology. The assay is performed on the proprietary T2Dx platform. The whole blood specimen, drawn into a blood collection tube containing K₂EDTA is used for the test. The blood collection tube containing a minimum of 3 mL of blood is loaded directly onto the T2Dx instrument as part of the assembled Cartridge, a single use self-contained unit that contains all of the reagents and disposables required to run a single test. Fully automated on the T2Dx, the blood specimen is mixed with the Lysis Reagent to lyse the red blood cells and the bacterial cells are concentrated by centrifygation. The Internal Control is added to the concentrated bacterial cells, which then undergo a bead beating step to lyse the bacteria cells. The supernatant containing the DNA from the lysed bacterial cells and the Internal Control are amplified with the target and Internal Control specific primers. The generated amplicon is then aliquoted into individual tubes containing target specific conjugated particles for Acinetobacter baumannii, Enterococcus faecium, Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus, and the Internal Control. These individual tubes are read in the MR reader and a signal is generated. Up to seven specimens can be loaded onto the T2Dx Instrument in parallel. When running a single specimen, the first result is reported in 3.5 hours from the specimen is loaded onto the instrument. The results are interpreted using the T2Dx applications software as valid or invalid, and if valid, target specific results are reported as Positive or Target not Detected. For one target, the Escherichia coli channel, results are reported as Positive, Indeterminate, or Target not Detected. An Indeterminate result is a valid result, but the presence or absence of Escherichia coli cannot be definitively assessed, and the indeterminate status applies only to the Escherichia coli channel. Results are displayed on the T2Dx touchscreen and can be printed. Raw T2MR data are not available to the end user.

These controls are not intended for use with other assays or systems. The T2Candida 1.1 Panel utilizes magnetic resonance-based detection (T2®MR technology) to qualitatively detect the same five species of Candida direct from K2EDTA-treated human whole blood. The T2Candida 1.1 Panel, run on the T2Dx instrument, performs sample concentration and Candida target DNA amplification for direct detection of species-specific amplicon. The test incorporates an Internal Control (IC) for monitoring test performance. The workflow for T2Candida 1.1 Panel is the same as the original cleared test and can only be performed on the T2Dx instrument, a bench-top, automated sample-to-result system, which performs all steps in the test after specimen loading. A design change was made to remove two foil-sealed tubes containing calcium hypochlorite ("bleach tubes") from the T2Candida Cartridge configuration and modify the software to remove the bleach transfer steps from the T2Dx workflow.

At the end of each assay, the T2Dx® Instrument uses a bleach solution to neutralize all liquids on the cartridge to mitigate the risk of amplicon contamination. The assay provides an identification of Candida albicans and/or Candida tropicalis, Candida parapsilosis, and Candida glabrata and/or Candida krusei. The test does not distinguish between C. albicans and C. tropicalis. The test does not distinguish between C. glabrata and C. krusei.
