Intended Use
Immunoassay for the in vitro quantitative determination of N-terminal pro-brain natriuretic peptide in human serum and plasma. The Elecsys proBNP II STAT assay is used as an aid in the diagnosis of individuals suspected of having congestive heart failure. The test is further indicated for the risk stratification of patients with acute coronary syndrome and congestive heart failure. The test may also serve as an aid in the assessment of increased risk of cardiovascular events and mortality in patients at risk for heart failure who have stable coronary artery disease. The electrochemiluminescence immunoassay "ECLIA" is intended for use on the cobas e 601 immunoassay analyzer.
Device Description
The proBNP II Assay is a sandwich immunoassay with two antibodies directed towards epitopes within the N-terminal portion of the proBNP molecule. The capture antibody is biotinylated to react with streptavidin-coated microparticles. The signal antibody is tagged with ruthenium. Both antibodies are monoclonal. The electrochemiluminescence immunoassay "ECLIA" is intended for use on the cobas e 601 immunoassay analyzer.
More Information

No
The summary describes a standard immunoassay and analyzer, with no mention of AI or ML in the intended use, device description, or performance studies.

No
The device is an in vitro diagnostic immunoassay that aids in diagnosis and risk stratification, but it does not directly treat or prevent disease.

Yes
The "Intended Use / Indications for Use" section explicitly states that the assay "is used as an aid in the diagnosis of individuals suspected of having congestive heart failure."

No

The device description explicitly states it is an immunoassay intended for use on a specific hardware analyzer (cobas e 601), and the performance studies are based on this hardware. It is a reagent/assay kit, not a software-only device.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states "Immunoassay for the in vitro quantitative determination of N-terminal pro-brain natriuretic peptide in human serum and plasma." The phrase "in vitro" is a key indicator of an IVD.
  • Sample Type: The test is performed on human serum and plasma, which are biological samples taken from the body but tested outside of it.
  • Purpose: The test is used as an aid in the diagnosis, risk stratification, and assessment of cardiovascular events, all of which are diagnostic purposes.
  • Device Description: The description details an "electrochemiluminescence immunoassay 'ECLIA'", which is a laboratory-based testing method.

All of these points align with the definition of an In Vitro Diagnostic device.

commonly used pharmaceuticals. No
interference with the assay was found.
• The risk of interference from potential
immunological interactions between
test components and rare sera has been
minimized by the inclusion of suitable
additives.
• As with all tests containing monoclonal
mouse antibodies, erroneous findings
may be obtained from samples taken
from patients who have been treated
with monoclonal mouse antibodies or
have received them for diagnostic
purposes.
• In rare cases, interference due to
extremely high titers of antibodies to
streptavidin and ruthenium can occur.
The test contains additives which
minimize these effects.
• For diagnostic purposes, the results
should always be assessed in
conjunction with the patient's medical
history, clinical examination and other
findingsSame

Dear Dr. Phillips:

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 (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. 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 (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in Title 21, Code of Federal Regulations (CFR), Parts 800 to 895. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Parts 801 and 809); medical device reporting (reporting of medical device-related adverse events) (21
