The device description details a standard immunoassay based on chemical reactions and optical measurement, with no mention of AI or ML algorithms for data analysis or interpretation.
No
The device is used to measure myoglobin levels to aid in diagnosis, not to treat a condition.
Yes
The "Intended Use / Indications for Use" states that the device is "an aid in the rapid diagnosis of acute myocardial infarction."
No
The device description clearly outlines a chemical assay process involving reagents, particles, magnetic separation, and color change measurement, indicating a hardware-based laboratory diagnostic system, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states that the device is used to "quantitatively measure myoglobin in human serum and plasma". This is a measurement performed in vitro (outside the body) on biological samples.
- Device Description: The description details a "one-step enzyme immunoassay" that analyzes a "sample" (human serum and plasma). This is a typical method used in in vitro diagnostics.
- Sample Type: The device uses "human serum and plasma," which are biological specimens analyzed in vitro.
- Purpose: The purpose is to "aid in the rapid diagnosis of acute myocardial infarction," which is a diagnostic application performed through the analysis of biological samples.
All these characteristics align with the definition of an In Vitro Diagnostic device.

Device Description
The MYO method for the Dimension® RxL system with the heterogeneous immunoassay module is a one-step enzyme immunoassay based on the "sandwich" principle. Sample is incubated with chromium dioxide particles (CrO-) coated with monoclonal antibodies specific for myoglobin and conjugate reagent (ß-galactosidase labeled monoclonal antibodies specific for myoglobin). A particle/MYO/coniugate sandwich forms during the incubation period. Unbound conjugate and analyte are removed by magnetic separation and washing. The sandwich bound ß-galactosidase is combined with the chromogenic substrate chlorophenol redß-d-galactopyranoside (CPRG) and catalyzes the hydrolysis of CPRG to the chromophore, chlorophenol red (CPR). The concentration of MYO present in the patient sample is directly proportional to the rate of color change measured at 577nm due to formation of CPR.
