No
The device description details a standard clinical chemistry assay based on enzymatic reactions and spectrophotometry. There is no mention of AI, ML, or any computational methods beyond standard data processing for calculating results from absorbance measurements.
No.
This device is an in vitro diagnostic assay used to quantify carbon dioxide in human serum or plasma for diagnostic purposes, not for treating a condition.
Yes
The device is explicitly stated to be used in the "diagnosis and treatment of numerous potentially serious disorders associated with changes in body acid-base balance" within the 'Intended Use / Indications for Use' section. This indicates its role in determining the nature or cause of a disease or condition.
No
The device description clearly outlines a chemical assay involving reagents and a reaction measured by absorbance, indicating a physical in vitro diagnostic test, not a software-only device.
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 carbon dioxide in human serum or plasma. This indicates it's used to analyze biological samples from the human body.
- Device Description: The "Device Description" further clarifies that it's an in vitro diagnostic assay for the quantitative determination of carbon dioxide in human serum or plasma.
- Mechanism: The description of the enzymatic reactions (using PEPC and MDH) and the measurement of absorbance changes are typical of in vitro diagnostic tests performed in a laboratory setting.
- Performance Studies: The performance studies describe testing with control materials and comparison to a predicate device, which are standard practices for validating IVD performance.
- Predicate Device: The mention of a "Predicate Device(s)" which is another IVD (Roche Cobas Mira Plus Automated Chemistry System Carbon Dioxide assay) further confirms its classification as an IVD.
The core function of the device is to analyze a biological sample (serum or plasma) outside of the body ("in vitro") to provide diagnostic information (quantitation of carbon dioxide for diagnosis and treatment of acid-base balance disorders). This aligns perfectly with the definition of an In Vitro Diagnostic device.

Device Description
Carbon Dioxide (CO2) is an in vitro diagnostic assay for the quantitative determination of carbon dioxide in human serum or plasma. The Carbon Dioxide assay is a clinical chemistry assay in which carbon dioxide, as bicarbonate (HCO3 ), and phospho(enol)pyruvate (PEP) are converted to oxalacetate and phosphate in the reaction, catalyzed by phospho(enol)pyruvate carboxylase (PEPC). Malate dehydorgenase (MDH) catalyzes the reduction of oxalacetate to malate with the concomitant oxidation of reduced nicotinamide adenine dinucleotide (NADH). The resulting decrease in absorbance at 380 nm is proportional to the CO2 content of 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 Carbon Dioxide assay method comparison yielded acceptable correlation with the Roche Cobas Mira Plus Automated Chemistry System Carbon Dioxide assay. The correlation coefficient = 0.9691, slope = 0.991, and Y-intercept = 2.779 mEq/L. Precision studies were conducted using the Carbon Dioxide 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 control is 3.6% and Level 2/Panel 112 control is 3.9%. The Carbon Dioxide assay is linear up to 40.0 mEq/L. The limit of quantitation (sensitivity) for the Carbon Dioxide assay is 4.0 mEq/L. These data demonstrate that the performance of the Carbon Dioxide assay is substantially equivalent to the performance of the Roche Cobas Mira Plus Automated Chemistry System Carbon Dioxide assay.
