Intended Use
MPO Flex® reagent cartridge: The MPO method is an in vitro diagnostic test for the quantitative measurement of myeloperoxidase (MPO) in human plasma on the Dimension® clinical chemistry system with the heterogeneous immunoassay module. Myeloperoxidase measurements may be used in conjunction with clinical history, ECG, and cardiac biomarkers to evaluate patients presenting with chest pain that are at risk for major adverse cardiac events, including myocardial infarction, need for revascularization, or death. MPO Calibrator: The MPO Calibrator is an in vitro diagnostic product intended to be used to calibrate the Myeloperoxidase (MPO) method on the Dimension® clinical chemistry system with the heterogeneous immunoassay module. MPO Control: The myeloperoxidase control is an in vitro diagnostic product intended for use as an assayed quality control product to monitor the performance of the Myeloperoxidase (MPO) method on the Dimension® clinical chemistry system with the heterogeneous immunoassay module.
Device Description
The MPO method is a one-step enzyme immunoassay based on the "sandwich" principle. The sample is incubated with chromium dioxide particles coated with monoclonal antibodies specific for MPO, and conjugate reagent (13-galactosidase labeled monoclonal antibodies specific for MPO). A particle/MPO/conjugate sandwich forms during the incubation period. Unbound conjugate is removed by magnetic separation and washing. The sandwich bound fl-galactosidase is combined with the chromogenic substrate chlorophenol red-ß-D-galactopyranoside (CPRG). Hydrolysis of CPRG releases a chromophore (CPR). The concentration of MPO present in the patient sample is directly proportional to the rate of color change due to formation of CPR measured at 577 nm.
More Information

No
The device description and performance studies focus on a standard enzyme immunoassay method for measuring myeloperoxidase. There is no mention of AI or ML in the text.

No.

The device is an in vitro diagnostic test used to measure a biomarker (myeloperoxidase) in human plasma, which aids in evaluating patients' risk for cardiac events. It does not provide treatment or directly alleviate symptoms.

Yes

The "Intended Use / Indications for Use" section explicitly states that the MPO reagent cartridge, calibrator, and control are "in vitro diagnostic tests" or "in vitro diagnostic products." Furthermore, it describes their use for the quantitative measurement of myeloperoxidase in human plasma to evaluate patients at risk for major adverse cardiac events, which is a clear diagnostic purpose.

No

The device description clearly outlines a "one-step enzyme immunoassay" involving reagents, particles, magnetic separation, washing, and measurement of color change at a specific wavelength. This indicates a physical, chemical, and optical process, not a software-only device.

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

The "Intended Use / Indications for Use" section explicitly states that the MPO Flex® reagent cartridge, MPO Calibrator, and MPO Control are "in vitro diagnostic test" or "in vitro diagnostic product". This is the primary indicator that the device falls under the category of IVDs.

Furthermore, the description of the device and its use in measuring myeloperoxidase in human plasma for evaluating patients with chest pain aligns with the definition of an in vitro diagnostic device, which is used to examine specimens derived from the human body to provide information for diagnostic purposes.
