For the in vitro quantitative determination of N-terminal proBrain natriuretic peptide in human serum and plasma.
Elecsys proBNP 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 electrochemiluminescence immunoassay "ECLIA" is intended for use on the Roche Elecsys 1010, Elecsys 2010 and MODULAR ANALYTICS E170 immunoassay analyzers
A device for the measurement of human proBNP in serum or plasma.
Here's a breakdown of the acceptance criteria and study information for the Elecsys® proBNP Immunoassay, based on the provided text:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are not explicitly stated as strict pass/fail thresholds in the provided document. Instead, the document presents a comparative analysis against a predicate device (Elecsys proBNP (K022516)) and another predicate for conceptual use (Triage BNP (K021317)). The "acceptance" is implied by demonstrating substantial equivalence to these legally marketed devices.
The table below summarizes the performance characteristics of the Elecsys proBNP (add'l indication) and compares them to the predicate devices. The "acceptance criteria" column reflects the performance of the primary predicate for the device.
| Feature | Acceptance Criteria (Elecsys proBNP K022516) | Reported Device Performance (Elecsys proBNP - add'l indication) |
|---|---|---|
| Precision | Within run: - 0.9%CV @ 474 pg/mL - 1.1%CV @ 8005 pg/mL - 0.9%CV @ 13682 pg/mL Total: - 5.8%CV @ 494 pg/mL - 4.1%CV @ 7827 pg/mL - 3.7%CV @ 13143 pg/mL E1010/2010 Within run: - 2.7%CV @ 175 pg/mL - 2.4%CV @ 355 pg/mL - 1.9%CV @ 1068 pg/mL - 1.8%CV @ 4962 pg/mL E1010/2010 Total: - 3.2%CV @ 175 pg/mL - 2.9%CV @ 355 pg/mL - 2.6%CV @ 1068 pg/mL - 2.3%CV @ 4962 pg/mL | Same as Elecsys proBNP (K022516) |
| Hook Effect | No effect up to 300,000 pg/ml | No effect up to 300,000 pg/ml |
| Analytical Sensitivity | 5 pg/mL | 5 pg/mL |
| Limitations (Interference) | Bilirubin: No interference up to 35 mg/dL Hemoglobin: No interference up to 1.4 g/dL Triglycerides: No interference up to 4000 mg/dL Biotin: No interference up to 30 ng/mL Rheumatoid Factor: No interference up to 1500 IU/mL | Same as Elecsys proBNP (K022516) |
| Measuring Range | 5-35,000 pg/mL | 5-35,000 pg/mL |
2. Sample Size Used for the Test Set and Data Provenance
The provided 510(k) summary does not contain specific details about the sample size used for the test set or the data provenance (e.g., country of origin, retrospective/prospective). It mainly focuses on the performance characteristics and comparison to predicate devices, but the underlying study details are not present.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not provided in the 510(k) summary. For an in vitro diagnostic device, "ground truth" for performance studies typically comes from reference methods, clinical diagnosis, or patient outcomes, rather than expert consensus on images or similar data.
4. Adjudication Method for the Test Set
This information is not provided in the 510(k) summary. Adjudication methods are more commonly described in studies where human interpretation of data is a variable (e.g., medical imaging studies).
5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, If So, What Was the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance
No, a multi-reader multi-case (MRMC) comparative effectiveness study was not done. This type of study is relevant for devices involving human interpretation, especially AI-assisted diagnostic tools. The Elecsys proBNP Immunoassay is a laboratory-based immunoassay, not an AI-powered image analysis or interpretation tool.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
Yes, the performance characteristics presented (precision, hook effect, analytical sensitivity, measuring range, limitations) represent the standalone performance of the immunoassay itself, without human-in-the-loop performance impacting the measurement results. The device quantifies a biomarker directly.
7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)
For the performance characteristics described:
- Precision and Analytical Sensitivity: Ground truth is established by well-defined analytical methods using control materials or spiked samples with known concentrations.
- Hook Effect: Established by testing samples with extremely high concentrations to determine if the assay accurately reports or produces a falsely low result.
- Limitations (Interference): Established by testing samples spiked with known interferents at various concentrations.
For the clinical indications for use (aid in diagnosis of CHF, risk stratification for ACS and CHF), the underlying ground truth would be established through clinical diagnosis, patient outcomes, and potentially other diagnostic tests in clinical trials (which are not detailed in this 510(k) summary).
8. The Sample Size for the Training Set
This information is not applicable and is not provided. The Elecsys proBNP Immunoassay is a traditional immunoassay, not a machine learning or AI-based device that requires a "training set" in the computational sense. The assay is developed and validated through biochemical and analytical testing.
9. How the Ground Truth for the Training Set Was Established
As noted above, this is not applicable for this type of device.

510(k) Summary, Continued
Substantial The device and test method contained within this premarket notification and described in the labeling is substantially equivalent to other devices legally equivalence marketed in the United States. We claim equivalence to the Roche Elecsys proBNP (K022516). Both products are intended for use in the quantitative determination of brain natriuretic peptides. The Triage BNP test (K021317) is used as predicate method for the conceptual description of how a biochemical marker can be used to provide prognostic information to a physician. Although this predicate method describes a different analyte, the description of how the test results should be interpreted with respect to the prognosis of the patient are substantially equivalent.

Dear Ms. Taylor:
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); and good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820). This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
