Intended Use
Access hsTnI is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of cardiac troponin I (cTnI) levels in human serum and plasma using the Access 2 Immunoassay Analyzers to aid in the diagnosis of myocardial infarction (MI).
Device Description
The Access hsTnI assay is a two–site immunoenzymatic ("sandwich") assay. Monoclonal anti–cTnI antibody conjugated to alkaline phosphatase is added to a reaction vessel along with a surfactant–containing buffer and sample. After a short incubation, paramagnetic particles coated with monoclonal anti–cTnI antibody are added. The human cTnI binds to the anti–cTnI antibody on the solid phase, while the anti–cTnI antibody–alkaline phosphatase conjugate reacts with different antigenic sites on the cTnI molecules. 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.

No.
The document describes a chemical immunoassay system for measuring cardiac troponin I levels. It details the chemical reactions and measurement principles. There is no mention of AI, machine learning, or deep learning, nor any indication of image processing or complex algorithmic decision-making that would suggest the presence of an AI model. The "analyte concentration is automatically determined from a stored calibration," which implies a rule-based or look-up table method, not an AI model.

No
This device is an immunoassay kit used for diagnosing myocardial infarction by quantitatively determining cardiac troponin I levels; it aids in diagnosis, but does not directly treat or prevent a disease.

Yes

The device is an immunoassay designed for the quantitative determination of cardiac troponin I levels in human serum and plasma, specifically to "aid in the diagnosis of myocardial infarction (MI)." This directly aligns with the definition of a diagnostic device as it provides information for disease diagnosis.

No

The device is a laboratory immunoassay for measuring cardiac troponin I levels. It involves physical reagents, an immunoassay analyzer (Access 2 Immunoassay Analyzers), and luminometer measurements. This clearly indicates a hardware-dependent chemical and optical process, not a software-only device.

Yes.
The device is described as an immunoassay for the quantitative determination of cardiac troponin I levels in human serum and plasma to aid in the diagnosis of myocardial infarction, which involves testing samples derived from the human body for diagnostic purposes.

Dear Mary Beth Tang:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

The extent of carryover observed was directly proportional to the cTnI concentration that was present in the high sample. In the studies, the estimated carryover was 3-5 pg/mL (ng/L) from a high sample at 270,000 pg/mL (ng/L) and 5-8 pg/mL (ng/L) from a high sample at 500,000 pg/mL (ng/L).
