Intended Use
The Bayer ADVIA IMS BNP method is for in vitro diagnostic use in the quantitative determination of B-type Natriuretic Peptide (BNP) in human plasma using the ADVIA IMS® System. This assay is indicated for the measurement of plasma BNP as an aid in the diagnosis and assessment of the severity of heart failure. In patients with acute coronary syndromes (ACS), this test, in conjunction with other known risk factors, can also be used to predict survival as well as to predict the likelihood of future heart failure. This assay is not intended for use on any other system.
Device Description
The ADVIA IMS BNP Assay is an in vitro immunoassay intended for the quantitative measurement of b-type natriuretic peptide (BNP) in human EDTA plasma covering the analytical range of 10 to approximately 6,000 pg/mL. The assay is a heterogeneous sandwich immunoassay using magnetic separation. Reagony a a freel genedus monoclonal antibody to BNP labeled with FITC and Reagent 2 (R2) contains the second monoclonal antibody to BNP (F(ab)2) conjugated to the enzyme /kaline phosphatase (ALP). The monoclonal antibodies used in the ADVIA IMS BNP assay are identical to those used in the ADVIA Centaur assay. The sandwich complex formed by the modite and the antibody conjugates is captured by the magnetic particles so that the BNP concentration in the sample can be measured in terms of enzyme activity. The substrate used for this assay is a dioxetane phosphate derivative, which is dephosphorylated by ALP resulting in photon emission. Luminescence is measured by a photomultiplier tube. The dose response curve is proportional to the analyte concentration in sample.

ADVIA IMS® System

No
The device description details a standard immunoassay using magnetic separation and luminescence detection. There is no mention of AI or ML in the intended use, device description, or performance studies. The performance studies focus on analytical performance metrics typical of in vitro diagnostic assays, not AI/ML model evaluation.

No
This device is an in vitro diagnostic (IVD) immunoassay designed for the quantitative determination of B-type Natriuretic Peptide (BNP) in human plasma, which is used as an aid in diagnosis and assessment of heart failure. It does not directly treat or prevent a medical condition.

Yes

The "Intended Use / Indications for Use" section explicitly states that the method is "for in vitro diagnostic use" and "is indicated for the measurement of plasma BNP as an aid in the diagnosis and assessment of the severity of heart failure." The "Device Description" also refers to it as an "in vitro immunoassay."

No

The device description clearly outlines a heterogeneous sandwich immunoassay using magnetic separation, reagents, enzymes, and luminescence measurement, indicating a hardware-dependent in vitro diagnostic system, not a software-only device.

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

Here's why:

  • Intended Use/Indications for Use: The very first sentence explicitly states "The Bayer ADVIA IMS BNP method is for in vitro diagnostic use". It also describes the intended use as the quantitative determination of BNP in human plasma to aid in the diagnosis and assessment of heart failure and predict outcomes in patients with acute coronary syndromes. This aligns perfectly with the definition of an in vitro diagnostic device, which is used to examine specimens taken from the human body to provide information for diagnosis, monitoring, or treatment.
  • Device Description: The description details an "in vitro immunoassay" that measures BNP in human EDTA plasma. It describes the reagents and the process of the assay, which is performed outside of the body using a biological sample.
  • Performance Studies: The performance studies described (Imprecision, Correlation, Interfering substances, Analytical Range, Minimum Detectable Concentration, Expected Results) are typical studies conducted to validate the performance of an in vitro diagnostic assay.
  • Predicate Device: The mention of a "Predicate Device(s)" which is the "ADVIA Centaur BNP Assay" further confirms its classification as an IVD, as predicate devices are used in the regulatory submission process for new IVDs.

Therefore, based on the provided information, the Bayer ADVIA IMS BNP method is clearly an In Vitro Diagnostic device.

The controls used in the ADVIA IMS BNP assay, QC BNP 1, 2, 3 (REF 02817045), are existing Bayer Centair products consisting of three levels of lyophilized controls. The controls contain various concentrations of BNP in buffered sodium caseinate with preservative.

f) Expected Results:

.

The expected values were determined from clinical studies performed for the predicate ADVIA Centaur BNP Test and results of the studies are included in the labeling for the ADVIA IMS BNP assay.

BNP concentrations in the Reference Group are shown in the tables below. The decision threshold was determined by the 95% confidence limit of BNP in the Reference population. The most appropriate decision threshold apparent from these distributions is 100 pg/mL. This BNP value translates into a general specificity of the test of greater than 97 %.

Reference Group

To establish the expected results, the circulating BNP concentration was determined from 1521 individuals without heart failure (785 women and 736 men). This population included apparently healthy individuals and individuals with hypertension, diabetes, renal insufficiency, and chronic obstructive pulmonary disease. The

descriptive statistics for BNP concentrations in the population without heart failure are shown in the following tables. These values are representative of the results obtained from clinical studies.
