The summary describes a standard in vitro diagnostic reagent and analyzer for measuring enzyme activity using photometric methods. There is no mention of AI or ML in the device description, intended use, or performance studies.
No.
This device is an in vitro diagnostic (IVD) reagent used for quantitative determination of Creatine Kinase activity, which aids in diagnosis and treatment, but does not directly provide therapy.
Yes
The "Intended Use / Indications for Use" section explicitly states that "Measurements of creatine phosphokinase activity are used in the diagnosis and treatment of myocardial infarction and muscle diseases". The device is also described as being for "in vitro diagnostic use only".
No
The device is a reagent cartridge used with a clinical analyzer, which are physical components, 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: "For in vitro diagnostic use only." It also describes the purpose of the device as the "quantitative determination of Creatine Kinase activity in serum or heparin plasma," which is a test performed outside of the body on biological samples.
- Device Description: The "Device Description" further clarifies that the reagent cartridge is used for "quantitative in vitro diagnostic determination of CK activity in serum or heparin plasma."
- Care Setting: The intended users are "clinical laboratories or physician office laboratories," which are typical settings for performing in vitro diagnostic tests.

Summary of Performance Studies
Precision: In testing at three CK levels for 22 days, the within-run CV ranged from 1.4 to 2.0%, and total CV ranged from 5.1 to 6.1%. In precision studies at three separate Physician Office Laboratory (POL) sites and in-house over five days, the within-run CVs ranged from 0.5 to 3.7% and total CVs ranged from 0.8 to 3.7%.
Accuracy: In a correlation study, 95 samples with CK values ranging from 32 to 1181 U/L were assayed on the S40 Clinical Analyzer using S-Test CK (y) and a comparative method (x). Least-squares regression analysis yielded a correlation coefficient of 0.998, a standard error estimate of 14.5, a confidence interval slope of 1.027 to 1.053, and a confidence interval intercept of -12.5 to -5.2. In patient correlation studies at three separate POL sites using the S40 Clinical Analyzer and a comparative method, least-squares regression analysis yielded correlation coefficients of 1.00, standard error estimates of 5.0 to 8.5, confidence interval slopes of 1.006 to 1.059, and a confidence interval intercepts of -10.8 to -3.5.
Sensitivity: The detection limit was 24 U/L.

§ 862.1215 Creatine phosphokinase/creatine kinase or isoenzymes test system.
(a)
Identification. A creatine phosphokinase/creatine kinase or isoenzymes test system is a device intended to measure the activity of the enzyme creatine phosphokinase or its isoenzymes (a group of enzymes with similar biological activity) in plasma and 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.(b)
