The description details a standard immunoassay technology based on chemical reactions and light measurement, with no mention of AI or ML algorithms for data analysis or interpretation. The performance studies focus on traditional analytical validation metrics like method comparison, imprecision, linearity, and limits of detection/quantitation.
No
This device is an immunoassay system designed to aid in the diagnosis of conditions by measuring CK-MB levels, not to treat them.
Yes
The assay is described as being used "to aid in the diagnosis and treatment of myocardial infarction and muscle diseases".
No
The device description clearly outlines a paramagnetic particle, chemiluminescent immunoassay which involves physical reagents and a luminometer, indicating it is a hardware-based diagnostic test, not software only.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use explicitly states it's for the "quantitative determination of CK-MB levels in human serum and plasma." This involves testing samples taken from the human body.
- Purpose: The purpose is to "aid in the diagnosis and treatment of myocardial infarction and muscle diseases." This is a diagnostic purpose.
- Method: The device uses a "paramagnetic particle, chemiluminescent immunoassay." This is a laboratory-based test performed on biological samples.
These characteristics clearly align 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, monitoring, or compatibility purposes.

Intended Use / Indications for Use
The Access CK-MB assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of CK-MB levels in human serum and plasma using the Access Immunoassay Systems to aid in the diagnosis and treatment of myocardial infarction and muscle diseases such as progressive, Duchenne-type muscular dystrophy.

Device Description
The Access CK-MB assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of CK-MB levels in human serum and plasma using the Access Immunoassay Systems to aid in the diagnosis and treatment of myocardial infarction and muscle diseases such as progressive, Duchenne-type muscular dystrophy. The Access CK-MB assay is a two-site immunoenzymatic ("sandwich") assay. Patient sample is added to a reaction vessel with mouse monoclonal anti-human CK-MB antibody-alkaline phosphatase conjugate and paramagnetic particles coated with mouse monoclonal anti-human CK-BB. Human serum CK-MB binds to the anti-CK-MB conjugate and is immobilized on the paramagnetic particle coated with anti-CK-BB. The CK-MB in the human serum or plasma binds to the immobilized anti-CK-BB on the solid phase by the sub-unit B epitope (common to CK-BB and CK-MB isoforms), while the mouse anti-CK-MB conjugate reacts specifically with the serum or the plasma CK-MB (no reaction with CK-MM or CK-BB isoforms).
After incubation, materials bound to the solid phase are held in a magnetic field while unbound materials are washed away. Then, the chemiluminescent substrate is added to the vessel and light generated by the reaction is measured with a luminometer. The light production is directly proportional to the concentration of analyte in the sample. Analyte concentration is automatically determined from a stored calibration.
