No
The summary describes a standard immunoassay technology (FPIA) and does not mention any AI/ML terms or concepts.

No.
This device is described as an immunoassay for the quantitative determination of digitoxin, which is a diagnostic function, not a therapeutic one.

Yes
The device is used for the "quantitative determination of digitoxin in human serum or plasma," which is a diagnostic measurement. It also refers to "immunoassays" and "correlation studies," which are characteristic of diagnostic devices.

No

The device description explicitly states "automated fluorescence polarization immunoassays (FPIA)," which is a laboratory-based hardware technology, not software only.

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

Here's why:

  • Intended Use: The intended use explicitly states "for the quantitative determination of digitoxin in human serum or plasma". This indicates the device is used to test samples taken from the human body (in vitro) to diagnose or monitor a condition (determining the level of digitoxin).
  • Device Description: The description mentions "automated fluorescence polarization immunoassays (FPIA)". Immunoassays are a common method used in IVD testing to detect and measure specific substances in biological samples.
  • Sample Type: The device is designed to analyze "human serum or plasma", which are biological samples commonly used in IVD testing.

These points clearly align with the definition of an In Vitro Diagnostic device.

Device Description

The Abbott AxSYM Digitoxin assay is substantially equivalence to the TDx/TDxFLx Digitoxin assay. Both assays are automated fluorescence polarization immunoassays (FPIA). The AxSYM Digitoxin standard calibrators and controls are to be used with the AxSYM Digitoxin reagents. The calibrators and controls are prepared gravimetrically using purfied material obtained from commercial sources. The calibrators and controls are verified using protocols involving multiple instrument testing. AxSYM Digitoxin reagent, calibrator and control expiration dates are based on real time stability testing.

510(k) Summary Abbott AxSYM® Digitoxin

Summary of Safety and Effectiveness Information Supporting a Substantial Equivalent Determination

The Abbott AxSYM Digitoxin assay is substantially equivalence to the TDx/TDxFLx Digitoxin assay. Both assays are automated fluorescence polarization immunoassays (FPIA). The intended use of both assays is for the quantitative determination of digitoxin in human serum or plasma (sodium heparin and potassium oxalate). Both assays are calibrated with Abbott calibrators. Abbott controls are used for verification of accuracy and precision of the AxSYM system when used for the quantitative determination of digitoxin in human serum or plasma. Correlation studies indicated the following results:

Slope: 0.96 Y-intercept: 0.58 Correlation Coefficient: 0.97 Std. Error of the Y estimate: 1.87 Number: 517
