Measurements of N-acetylprocainamide are used in the diagnosis and treatment of procainamide overdose and in monitoring serum or plasma levels of N-acetylprocainamide to ensure appropriate therapy. This diagnostic method is not intended for use on any other system. ## Device Story In vitro diagnostic assay for quantitative measurement of N-acetylprocainamide (NAPA) in human serum or plasma; utilizes Enzyme Multiplied Immunoassay Technique (EMIT) on Bayer Immuno 1 system; intended for clinical laboratory use to monitor therapeutic levels and manage procainamide overdose; provides concentration values to clinicians for therapeutic decision-making. ## Clinical Evidence Bench testing only. Performance compared to predicate using 99 samples. Correlation: y = 0.99x - 0.03, r = 0.99, Syx = 0.29 µg/mL. Precision (total) reported at 5.5% @ 1.7 µg/mL, 4.3% @ 4.2 µg/mL, and 6.5% @ 8.7 µg/mL. Minimum detectable concentration: 0.11 µg/mL. ## Technological Characteristics In vitro diagnostic immunoassay using EMIT technology. Designed for use on Bayer Immuno 1 system. Analyte: N-acetylprocainamide. Sample matrix: human serum or plasma (lithium heparin). ## 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 - Syva EMIT® N-Acetylprocainamide Assay ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
