Device Description
The Spectral Diagnostics Multiquant® Quantitative Myoglobin Test is an automated latex immunoturbidometric method. The test utilizes a monoclonal antibody and a polyclonal antibody each covalently bound to polystyrenesupercarboxylated latex particles. When serum or plasma and assay buffer are combined with the latex particles, myoglobin in the specimen crosslinks adjacent latex beads and produces an increase in the turbidity of the solution. The turbidity, measured at 600nm, is proportional to the concentration of myoglobin present in the serum or plasma.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
In a methods correlation against the Stratus® Myoglobin Fluorometric Assay the correlation coefficient was 0.99 and a regression equation of Multiquant® = 1.04(Stratus ) + 0.0, N= 172, r = 0.99 , range = 7.6 to 496.3 ng/mL was obtained with serum samples.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Within run precision and between run precision were 3.59% and 6.48% respectively for a sample containing 32.08 mg/mL myoglobin and 2.03% and 2.74% respectively for a sample containing 288.72 mg/mL.

Spectral Diagnostics Inc. Multiquant® Quantitative Myoglobin Test 510(k) Notification
PREMARKET NOTIFICATION 510(k) SUMMARY OF SAFETY AND EFFECTIVENESS
Myoglobin is an oxygen-binding heme protein with a molecular weight of 17,800 daltons. normally found in cardiac and skeletal tissue which serves as an oxygen-storing pigment necessary for a high level of oxidative phosphorylation. It constitutes about 2% of the total muscle protein and is located in the cell. Cell injury or death during acute myocardial infarction (AMI) has been shown to release myoglobin into the blood. Blood myoglobin reaches the upper limit of normal approximately 2-3 hours after the onset of symptoms. The concentration of myoglobin has been shown to peak at 9-12 hours and to return to normal within 24-36 hours after an AMI.1-2 A number of reports have been published detailing the clinical utility of myoglobin in the early diagnosis and monitoring of AMI.36
The Spectral Diagnostics Multiquant® Quantitative Myoglobin Test is an automated latex immunoturbidometric method. The test utilizes a monoclonal antibody and a polyclonal antibody each covalently bound to polystyrenesupercarboxylated latex particles. When serum or plasma and assay buffer are combined with the latex particles, myoglobin in the specimen crosslinks adjacent latex beads and produces an increase in the turbidity of the solution. The turbidity, measured at 600nm, is proportional to the concentration of myoglobin present in the serum or plasma.
The safety and effectiveness of the Spectral Diagnostics Multiquant® Quantitative Myoglobin Test is demonstrated by its substantial equivalency to Dade-Behring Stratus® Myoglobin Fluorometric Assay. Both tests for myoglobin are used to measure myoglobin in serum and plasma and both use immochemical technologies. In a methods correlation against the Stratus® Myoglobin Fluorometric Assay the correlation coefficient was 0.99 and a regression equation of Multiquant® = 1.04(Stratus ) + 0.0, N= 172, r = 0.99 , range = 7.6 to 496.3 ng/mL was obtained with serum samples. Within run precision and between run precision were 3.59% and 6.48% respectively for a sample containing 32.08 mg/mL myoglobin and 2.03% and 2.74% respectively for a sample containing 288.72 mg/mL.

Existing major regulations affecting your device can be found in the Code of Federal Requlations, 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 Druq Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in requlatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. 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.
