Intended Use
The TOBR FLEX™ reagent cartridge used on the Dimension® clinical chemistry system is an in vitro diagnostic test intended to measure tobramycin, an aminoglycoside antibiotic drug, in plasma and serum. Measurements obtained by this device are used in the diagnosis and treatment of tobramycin overdose and in monitoring levels of tobramycin to ensure appropriate therapy.
Device Description
The TOBR method is based on Particle Enhanced Turbidimetric Inhibition Immunoassay (PETINIA) technique which uses a latex particle-tobramycin conjugate and tobramycin-specific monoclonal antibody.

No
The description details a turbidimetric immunoassay technique, which is a standard chemical analysis method and does not mention any AI or ML components.

No.
The device is an in vitro diagnostic test used to measure tobramycin levels, aiding in diagnosis and monitoring, but it does not directly treat or prevent a disease and is therefore not a therapeutic device.

Yes

The "Intended Use / Indications for Use" section explicitly states that the device is "an in vitro diagnostic test" and that its measurements are "used in the diagnosis and treatment of tobramycin overdose."

No

The device is a reagent cartridge used on a clinical chemistry system, which are physical components and not software-only.

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 device is an "in vitro diagnostic test intended to measure tobramycin... in plasma and serum." This is the primary characteristic of an IVD.
  • Sample Type: The device measures a substance (tobramycin) in biological samples (plasma and serum) taken from the human body. This is a key aspect of IVD testing.
  • Purpose: The measurements are used "in the diagnosis and treatment of tobramycin overdose and in monitoring levels of tobramycin to ensure appropriate therapy." This indicates a medical purpose related to diagnosis and treatment, which is the function of an IVD.
  • Device Description: The description of the method (PETINIA) confirms it's a laboratory-based test performed on samples outside the body.

The information provided clearly aligns with the definition and purpose of an In Vitro Diagnostic device.

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

One hundred forty-one samples were tested with the TOBR FLEX™ reagent cartridge on the Dimension® system and the aca® TOBRA test pack on the aca® discrete clinical analyzer, with the following results: slope = 0.99, intercept = 0.10, correlation coefficient = 0.989, range of samples = 0-12 µg/mL.

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

slope = 0.99 intercept = 0.10 correlation coefficient = 0.989 range of samples = 0-12 µg/mL

Tobramycin FLEXTM Reagent Cartridge

Summary of Safety and Effectiveness

The TOBR FLEX™ reagent cartridge used on the Dimension® clinical chemistry system is an in vitro diagnostic test intended to measure tobramycin, an aminoglycoside antibiotic drug, in plasma and serum. Measurements obtained by this device are used in the diagnosis and treatment of tobramycin overdose and in monitoring levels of tobramycin to ensure appropriate therapy.

The TOBR method is based on Particle Enhanced Turbidimetric Inhibition Immunoassay (PETINIA) technique which uses a latex particle-tobramycin conjugate and tobramycin-specific monoclonal antibody.

The TOBR FLEX™ reagent cartridge is substantially equivalent to the aca® tobramycin analytical test pack, which was cleared by the FDA via the 510(k) process. Both tests use prepackaged reagents for the determination of tobramycin in human serum or plasma.

One hundred forty-one samples were tested with the TOBR FLEX™ reagent cartridge on the Dimension® system and the aca® TOBRA test pack on the aca® discrete clinical analyzer, with the following results:

slope = 0.99 intercept = 0.10 correlation coefficient = 0.989 range of samples = 0-12 µg/mL
