Intended Use

AxSYM® Myoglobin is a Microparticle Enzyme Immunoassay (MEIA) for the quantitative determination of myoglobin in human serum or plasma on the AxSYM System. Measurements obtained by this device aid in the rapid diagnosis of heart or renal disease.

Device Story

AxSYM Myoglobin is a Microparticle Enzyme Immunoassay (MEIA) used on the Abbott AxSYM System. It measures myoglobin concentrations in human serum or plasma samples. The device utilizes antibodies specific for myoglobin to generate a fluorescent signal proportional to the myoglobin concentration in the sample. The assay is automated and intended for use in clinical laboratory settings. Results are used by healthcare providers to assist in the rapid diagnosis of heart or renal disease, providing quantitative data to support clinical decision-making.

Clinical Evidence

Bench testing only. A comparative study was performed between the AxSYM Myoglobin assay and the predicate Dade Stratus Myoglobin assay using 383 clinical specimens. Results showed a correlation coefficient of 0.981, a slope of 1.09 (95% CI: 1.07 to 1.11), and a y-axis intercept of 1.0 ng/mL (95% CI: -3.7 to 5.7).

Technological Characteristics

Microparticle Enzyme Immunoassay (MEIA) technology. Uses antibodies specific for myoglobin. Automated system. Fluorescent signal detection proportional to analyte concentration. Designed for use on the Abbott AxSYM System.

Indications for Use

Indicated for the quantitative determination of myoglobin in human serum or plasma to aid in the rapid diagnosis of heart or renal disease.

Regulatory Classification

Identification

A myoglobin immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the myoglobin (an oxygen storage protein found in muscle) in serum and other body fluids. Measurement of myoglobin aids in the rapid diagnosis of heart or renal disease.

## 510(k) Summary Abbott AxSYM® Myoglobin

## Summary of Safety and Effectiveness Information Supporting a Substantially Equivalent Determination

The following information as presented in the Premarket Notification [510(k)] for Abbott AxSYM® Myoglobin constitutes data supporting a substantially equivalent determination.

AxSYM Myoglobin is a Microparticle Enzyme Immunoassay (MEIA) for the quantitative determination of myoglobin in human serum or plasma. AxSYM Myoglobin is calibrated with Abbott AxSYM Myoglobin Calibrators. Abbott AxSYM Myoglobin Controls are assayed for the verification of the accuracy and precision of the Abbott AxSYM System.

Substantial equivalence has been demonstrated between the AxSYM Myoglobin assav and the Dade Stratus® Myoglobin Fluorometric Enzyme Immunoassay. The intended use of the AxSYM Myoglobin assay is for the quantitative determination of myoglobin in human serum or plasma. The intended use of the Dade Stratus Myoglobin assay is for the determination of myoglobin concentrations in serum and plasma to aid in the rapid diagnosis of acute myocardial infarction.

Both assays are automated, in vitro immunoassays that use antibodies specific for myoglobin. The fluorescent signal measured by both assays is directly related to the concentration of myoglobin in the sample. A least squares linear regression analysis between these two assays, using 383 specimens within the dynamic range of both assays, yielded a correlation coefficient of 0.981, a slope of 1.09 (95% confidence interval of 1.07 to 1.11), and a y-axis intercept of 1.0 ng/mL (95% confidence interval of -3.7 to 5.7).

Dear Ms. Granitz:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we 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). 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 aqainst misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Reqister. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
