Regulation numbers,: 21 CFR 862.1160
A bicarbonate/carbon dioxide test system is a device intended to measure bicarbonate/carbon dioxide in plasma, serum, and whole blood.
Bicarbonate/carbon dioxide measurements are used in the diagnosis and treatment of numerous potentially serious disorders associated with changes in body acid-base balance. The intended patient population may be adult, pediatric, and neonatal, while the environment of use may be a hospital (e.g., respiratory care or laboratory department), urgent care situations (e.g., intensive care unit, surgery, emergency department), or bedside/near patient care situations.
The following eight performance characteristics (#1 Method Comparison - #8 Expected Values) should be included in the submission. Data should be provided that supports the use of the device with the specimen type(s) that are claimed to be appropriate for analysis:
A method comparison study as described above, comparing performance with that of the predicate device as well as an appropriate reference method should be conducted to demonstrate substantial equivalence. A statistically significant sample of patients from a population representing the proposed intended use should be included in the study, spanning the appropriate assay range.
Refer to 21 CFR 809.10.
Other: For a multi-purpose instrument used for diagnostic purposes refer to 21 CFR 809.10 (b) (1),(2),(6),(14),and (15).
