Correlation study comparing AxSYM Procainamide to TDx/TDxFLx predicate (n=205) yielded slope 0.98, y-intercept 0.1, and correlation coefficient 0.989. ## Technological Characteristics Automated fluorescence polarization immunoassay (FPIA). Reagents, calibrators, and controls prepared gravimetrically. Real-time stability testing performed for expiration dating. ## Regulatory Identification A digoxin test system is a device intended to measure digoxin, a cardiovascular drug, in serum and plasma. Measurements obtained by this device are used in the diagnosis and treatment of digoxin overdose and in monitoring levels of digoxin to ensure appropriate therapy. ## Predicate Devices - TDx/TDxFLx Procainamide assay ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

Substantial equivalence has been demonstrated between the AxSYM Procainamide assay and the TDx/TDxFLx Procainamide assay. Both assays are automated fluorescence polarization immunoassays (FPIA). The intended use of both assays is for the quantitative determination of procainamide in human serum or plasma (sodium heparin, tripotassium EDTA, potassium oxalate, and sodium citrate). Both assays are calibrated with Abbott calibrators. Abbott controls are assayed controls used for verification of the accuracy and precision of the AxSYM system. Correlation studies indicated the following results: Slope: 0.98 Y-Intercept: 0.1 Correlation Coefficient: 0.989 Std. Error of the Y estimate: 0.056 Number: 205 The AxSYM Procainamide standard calibrators and controls are to be used with the AxSYM Procainamide reagents. The calibrators and controls are prepared gravimetrically using purified material obtained from commercial sources. The calibrators and controls are verified using protocols involving multiple instrument testing. AxSYM Procainamide reagent, calibrator and control expiration dates are based on real time stability testing.
