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
