The device description details a standard enzyme-linked immunoassay (ELISA) method for measuring Troponin I. There is no mention of AI or ML in the intended use, device description, or any of the "Mentions" sections. The dose response curve is constructed using a linear point-to-point fit, which is a traditional statistical method, not AI/ML.
No
The device is an in vitro diagnostic method designed to measure cardiac Troponin I levels to aid in the diagnosis of acute myocardial infarction and risk stratification, not to provide therapy.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states "This in vitro diagnostic method..." and describes its use in aiding the diagnosis of acute myocardial infarction.
No
The device description clearly outlines a complex in vitro diagnostic method involving reagents, magnetic particles, enzymatic reactions, and absorbance measurements, indicating a hardware-dependent system.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that this is an "in vitro diagnostic method intended to quantitatively measure the concentration of cardiac Troponin 1 (Tn1) in human serum and plasma". This directly aligns with the definition of an in vitro diagnostic device, which is used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The description details a laboratory assay that analyzes human serum and plasma samples to measure a specific analyte (Troponin I). This is a typical characteristic of an IVD.
- Purpose: The intended use clearly states that the measurements "aid in the diagnosis of acute myocardial infarction (AMI) and in the risk stratification of patients with non-ST segment-elevation, acute coronary syndromes". This diagnostic purpose is central to the function of an IVD.

Intended Use / Indications for Use
This in vitro diagnostic method intended to quantitatively measure the concentration of cardiac Troponin 1 (Tn1) in human serum and plasma (lithium heparin) using the Bayer Immuno 1 system. When used in conjunction with other clinical data, such as presenting symptoms and diagnostic procedures, measurements of cardiac Tnl aids in the diagnosis of acute myocardial infarction (AMI) and in the risk stratification of patients with non-ST segment-elevation, acute coronary syndromes with respect to relative risk of mortality, myocardial infarction, or increased probability of ischemic events requiring urgent revalcularization procedures.
This diagnostic method is not intended for use on any other system.

Device Description
The proposed Bayer Immuno 1™ Troponin I assay is an enzyme label sandwich assay using a monoclonal and polyclonal antibody. A Troponin I specific monoclonal antibody is labeled with fluorescein and a Troponin I specific goat affinity purified antibody is labeled with alkaline phosphatase (ALP). The solid phase consists of a suspension of magnetizable particles coated with antibody to fluorescein (mIMP reagent). Sample or calibrator, R1 reagent containing fluoresceinantibody conjugate, R2 reagent containing ALP-antibody conjugate and mIMP reagent are mixed and incubated at 37° C. In the presence of Troponin I a (fluorescein-conjugate: Troponin I:ALPconjugate) complex is formed and captured by the anti-fluorescein antibodies on the magnetic particles. The particles are washed and para-nitrophenyl phosphate solution is added. The ALP in the antibody conjugate reacts with the substrate to form para-nitrophenoxide and phosphate. Increasing absorbance due to the formation of para-nitrophenoxide is monitored at 405 nm and 450 nm. The dose response curve is directly proportional to the concentration of Troponin I in the sample. A linear point to point fit is used to construct the dose response curve. The Bayer Immuno 1 Troponin I assay has a range of 0 to 200 ng/mL and liguid calibrators are provided with values of 0,5,10,20,60, and 200 ng/mL Troponin I.
The Bayer Immuno 1 Troponin I Assay was previously cleared under Document Control No. K973616. The proposed Bayer Immuno 1 Troponin I Assay is substantially equivalent in technical performance and intended use to the FDA cleared device. Changes are limited to modifications in the indications for use. The additional indication for use is:
...in the risk stratification of patients with non-ST segment elevation acute coronary syndromes with respect to relative risk of mortality, myocardial infarction or increased probability of ischemic events requiring urgent revascularization procedures.

Dear Mr. Muraca:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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 (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
