The Creatine Kinase assay is used for the quantitation of creatine kinase in human serum. Measurements of creatine phosphokinase and its isoenzymes are used in the diagnosis and treatment of myocardial infarction and muscle diseases such as progressive Duchenne-type muscular dystrophy.
Device Description
Creatine Kinase (CK) is an in vitro diagnostic assay for the quantitative determination of creatine kinase activity in human serum. The Creatine Kinase assay is a clinical chemistry assay in which creatine kinase in the sample catalyzes the transfer of a high energy phosphate group from creatine phosphate to ADP. The ATP produced in this reaction is subsequently used to phosphorylate glucose to produce glucose-6-phosphate (G-6-P) in the presence of hexokinase. G-6-P is then oxidized by glucose-6-phosphate dehydrogenase (G-6-PDH) with the concomitant reduction of NAD to NADH. The rate of formation of NADH is monitored at 340 nm and is proportional to the activity of CK in the sample. This reagent also contains AMP and di-(adenosine-5')-pentaphoshate to prevent interference from adenylate kinase.

No
The device description details a standard in vitro diagnostic assay based on enzymatic reactions and spectrophotometric measurement. There is no mention of AI, ML, image processing, or any data-driven algorithms beyond standard statistical analysis for performance evaluation.

No.
A therapeutic device is used to treat or cure a disease. This device is an in vitro diagnostic assay used to measure creatine kinase, which aids in the diagnosis and treatment of conditions, but it does not treat or cure them itself.

Yes

The "Intended Use / Indications for Use" section explicitly states that "Measurements of creatine phosphokinase and its isoenzymes are used in the diagnosis and treatment of myocardial infarction and muscle diseases such as progressive Duchenne-type muscular dystrophy." This indicates that the device aids in the diagnosis of medical conditions.

No

The device description clearly outlines a chemical assay that involves reagents and a reaction monitored at a specific wavelength, indicating a physical, in vitro diagnostic device, 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 assay is used for the "quantitation of creatine kinase in human serum" and that these measurements are used in the "diagnosis and treatment of myocardial infarction and muscle diseases". This clearly indicates that the device is intended to be used in vitro (outside the body) to examine specimens (human serum) for the purpose of providing information for diagnosis and treatment.
  • Device Description: The "Device Description" further clarifies that it is an "in vitro diagnostic assay for the quantitative determination of creatine kinase activity in human serum." It describes the chemical reactions that occur in vitro to measure the CK activity.

These points align directly with the definition of an In Vitro Diagnostic device.

Summary of Performance Studies

Comparative performance studies were conducted using the ALCYON™ Analyzer. The Creatine Kinase assay method comparison yielded acceptable correlation with the Roche Cobas Mira Plus Automated Chemistry System CK NAC assay. Precision studies were conducted using the Creatine Kinase assay. Within-run, between-run, and between-day studies were performed using two levels of control material. The Creatine Kinase assay is linear up to 2,100 U/L. The limit of quantitation (sensitivity) for the Creatine Kinase assay is 12 U/L.

Key Metrics

correlation coefficient = 0.9972. slope = 1.007, and Y-intercept = - 8.757 U/L. The total %CV for Level 1/Panel 111 is 2.6% and 2.3% for Level 2/ Panel 112. The Creatine Kinase assay is linear up to 2,100 U/L. The limit of quantitation (sensitivity) for the Creatine Kinase assay is 12 U/L.
