No
The device description clearly describes a chemical assay that measures the rate of decrease in absorbance at 340 nm, indicating a physical/chemical process involving reagents and a measurement system, not solely software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The "Intended Use / Indications for Use" section explicitly states that the assay is used for the quantitation of aspartate aminotransferase in human serum or plasma. This indicates it's used to analyze biological samples from the human body.
- Purpose: The intended use also states that these measurements are used in the diagnosis and treatment of certain types of liver and heart disease. This aligns with the definition of an IVD, which is used to provide information for diagnostic purposes.
- Device Description: The "Device Description" further clarifies that it is an in vitro diagnostic assay for the quantitative determination of aspartate aminotransferase in human serum or plasma. It also describes the chemical reactions involved, which are performed outside of the body (in vitro).
Therefore, based on the provided information, this device clearly fits the definition of an In Vitro Diagnostic.

Device Description
Aspartate Aminotransferase is an in vitro diagnostic assay for the quantitative determination of aspartate aminotransferase in human serum or plasma. The Aspartate Aminotransferase assay is a clinical chemistry assay. Lactate dehydrogenase (LD) is added to prevent interference from endogenous a-keto acids. Aspartate aminotransferase in the sample catalyzes the transfer of the amino group from aspartate to x-ketogluterate to form oxalacetate and glutamate. The oxalacetate formed is reduced to malate in the presence of malate dehydrogenase (MD) with the concurrent oxidation of reduced nicotinamide adenine dinucleotide (NADH) to nicotinamide adenine dinucleotide (NAD). The resulting rate of decrease in absorbance at 340 nm is proportional to the AST activity in the sample.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparative performance studies were conducted using the ALCYON™ Analyzer. The Aspartate Aminotransferase assay method comparison vielded acceptable correlation with the Roche Cobas Mira Plus Automated Chemistry System Aspartate Aminotransferase assay. The correlation coefficient = 0.9967, slope = 0.935, and Y-intercept = 2.794 U/L. Precision studies were conducted using the Aspartate Aminotransferase assay. Within-run, between-run, and between-day studies were performed using two levels of control material. The total %CV for Level 1/ Panel 111 is 9.2% and Level 2/Panel 112 is 2.3%. The Aspartate Aminotransferase assay is linear up to 430 U/L. The limit of quantitation (sensitivity) for the Aspartate Aminotransferase assay is 9 U/L. These data demonstrate that the performance of the Aspartate Aminotransferase assay is substantially equivalent to the performance of the Roche Cobas Mira Plus Automated Chemistry System Aspartate Aminotransferase assay.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
