No
The device description details a standard clinical chemistry assay based on a chemical reaction and spectrophotometric measurement. There is no mention of AI, ML, or any computational analysis beyond basic quantitative calculations.
No.
The device is an in vitro diagnostic assay used for the quantitative determination of calcium levels, which aids in diagnosis and treatment monitoring, but it does not directly provide therapy.
Yes
The "Intended Use / Indications for Use" section explicitly states that "Calcium measurements are used in the diagnosis and treatment of parathyroid disease, a variety of bone diseases, chronic renal disease, and tetany". This indicates the device is used for diagnostic purposes.
No
The device is an in vitro diagnostic assay that uses chemical reactions and a spectrophotometer (implied by measurement at 600 nm) to determine calcium concentration. This involves physical reagents and hardware, not just 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 calcium in human serum, plasma, or urine and that these measurements are used in the diagnosis and treatment of various diseases. This directly aligns with the definition of an IVD, which is used to examine specimens derived from the human body 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 calcium in biological samples.
- Mechanism: The description of the chemical reaction (arsenazo-III dye reacting with calcium) and the measurement of the resulting color change at a specific wavelength confirms that the analysis is performed in vitro (outside the body) on a sample.
Therefore, based on the provided information, this device clearly fits the definition of an In Vitro Diagnostic.

Intended Use / Indications for Use
The Calcium assay is used for the quantitation of calcium in human serum, plasma, or urine. Calcium measurements are used in the diagnosis and treatment of parathyroid disease, a variety of bone diseases, chronic renal disease, and tetany (intermittent muscular contractions or spasms).

Device Description
Calcium is an in vitro diagnostic assay for the quantitative determination of calcium in serum, plasma, or urine. The Calcium assay is a clinical chemistry assay in which arsenazo-III dye reacts with calcium in an acid solution to form a blue-purple complex. The color developed is measured at 600 nm and is proportional to the calcium concentration in the sample.

Summary of Performance Studies
Comparative performance studies were conducted using the ALCYON™ Analyzer. The Calcium assay method comparison yielded acceptable correlation with the Boehringer Mannheim Calcium assay on the Hitachi 717 Analyzer. For the serum application, the correlation coefficient = 0.9624, slope = 0.979, and Y-intercept = 0.492 mg/dL. For the urine application, the correlation coefficient = 0.9981, slope = 0.989, and Y-intercept = - 0.094 mg/dL. Precision studies were conducted using the Calcium assay. Within-run, between-run, and between-day studies were performed using two levels of control material. For the serum application, the total %CV is for Level 1/Panel 111 is 1.7% and Level 2/Panel 112 is 2.9%. For the urine application, the total % CV for Level 1/Panel 131 is 6.8% and Level 2/Panel 132 is 3.1%. The Calcium assay is linear up to 18 mg/dL. The limit of quantitation (sensitivity) of the Calcium assay is 0.865 mg/dL. These data demonstrate that the performance of the Calcium assay is substantially equivalent to the performance of the Boehringer Mannheim Calcium assay on the Hitachi 717 Analyzer for both serum and urine applications.
