No
The device description and performance studies focus on a standard chemical assay and its analytical performance metrics, with no mention of AI or ML.
No
This device is an in vitro diagnostic assay used for the quantitative determination of ammonia in human plasma, which is for diagnostic purposes, not therapeutic intervention.
Yes
The "Intended Use / Indications for Use" section states: "The Ammonia assay is used for the quantitation of ammonia in human plasma." and the "Device Description" section states: "Ammonia is an in vitro diagnostic assay for the quantitative determination of ammonia in human plasma." This clearly indicates its use for diagnostic purposes.
No
The device is described as an "in vitro diagnostic assay" which utilizes chemical reactions and measures absorbance. This indicates a physical test kit or system, not purely 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 ammonia in human plasma. This is a diagnostic purpose performed in vitro (outside the body).
- Device Description: The "Device Description" further clarifies that it is an "in vitro diagnostic assay for the quantitative determination of ammonia in human plasma." It describes the chemical reactions used to measure ammonia in a sample.
- Performance Studies: The performance studies compare the device to a predicate device (K870787 A-GENT® Ammonia assay), which is also an IVD. This comparison is typical for demonstrating the performance of a new IVD.
All of these points align with the definition and characteristics of an In Vitro Diagnostic device.

Device Description
Ammonia is an in vitro diagnostic assay for the quantitative determination of ammonia in human plasma. The Ammonia assay is a clinical chemistry assay which utilizes the amination of x-ketoglutarate by ammonia (NH3) along with the concomitant oxidation of NHzDPH. These reactions, catalyzed by glutamate dehydrogenase (GLDH), produce glutamate and NH2DP*. The oxidation of NHxDPH produces a decrease in absorbance at 340 nm which is directly proportional to the concentration of ammonia in the sample.

Summary of Performance Studies
Comparative performance studies were conducted using the AEROSET™ System. The Ammonia assay method comparison vielded acceptable correlation with the A-GENT Ammonia assay on the ABBOTT SPECTRUM Series II System. Precision studies were conducted using the Ammonia assay. Within-run, between-run, and between-day studies were performed using three levels of control material.
Key Metrics
The correlation coefficient = 0.9957, slope = 0.971, and Y-intercept = -2.083 umol/L. The total %CV for Level 1/Panel 103 is 11.7%, 4.0% for Level 2/Panel 104, and 5.5% for Level 3/Panel 105. The Ammonia assay is linear up to 1.574.9 umol/L. The limit of quantitation (sensitivity) of the Ammonia assay is 20.6 umol/L.

§ 862.3200 Clinical toxicology calibrator.
(a)
Identification. A clinical toxicology calibrator is a device intended for medical purposes for use in a test system to establish points of reference that are used in the determination of values in the measurement of substances in human specimens. A clinical toxicology calibrator can be a mixture of drugs or a specific material for a particular drug (e.g., ethanol, lidocaine, etc.). (See also § 862.2 in this part.)(b)
Classification. Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9.
