Intended Use
The ONLINE TDM Valproic Acid assay is for the quantitative determination of valproic acid in human serum or plasma on Roche automated clinical chemistry analyzers. Measurements muman serain of paintine were used in the diagnosis and treatement of valproic acid overdose and in monitoring the levels of valproic acid to help ensure appropriate therapy.
Device Description
The ONLINE TDM Valproic Acid assay is for the quantitative determination of valproic acid in human serum or plasma on Roche automated clinical chemistry analyzers. The proposed labeling indicates the Roche Hitachi 911, 912, 917 and Modular P analyzers can be used with the Roche ONLINE TDM Valproic Acid reagent kits. The assay is based on a homogeneous enzyme immunoassay technique used for the quantitative analysis of valproic acid (free and protein-bound) in human serum or plasma. The assay is based on competition between drug in the sample and drug labeled with the enzyme glucose-6-phosphate dehydrogenase (G6PDH) for antibody binding sites. Enzyme activity decreases upon binding to the antibody, so the drug concentration in the sample can be measured in terms of enzyme activity. Active enzyme converts oxidized nicotinamide adenine dinucleotide (NAD) to NADH, resulting in an absorbance change that is measured spectrophotometrically. Endogenous serum G6PDH does not interfere because the coenzyme functions only with the bacterial (Leuconostoc mesenteroids) enzyme employed in the assay.
More Information

No
The description details a standard enzyme immunoassay for quantitative determination of valproic acid. There is no mention of AI, ML, or any computational algorithms beyond basic data processing for spectrophotometric measurements.

No.
The device is an in-vitro diagnostic assay for measuring valproic acid levels, not a device for treating a condition or disease.

Yes

The device quantitatively determines valproic acid levels in human serum or plasma, and these measurements are explicitly stated to be "used in the diagnosis and treatment of valproic acid overdose and in monitoring the levels of valproic acid to help ensure appropriate therapy," which are clear diagnostic applications.

No

The device description clearly states it is an "assay" and a "reagent kit" used on automated clinical chemistry analyzers, indicating it is a chemical/biological product and 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 for the quantitative determination of valproic acid in human serum or plasma. It also mentions that these measurements are used in the diagnosis and treatment of valproic acid overdose and in monitoring levels to help ensure appropriate therapy. These are all hallmarks of an in vitro diagnostic device, which is used to examine specimens from the human body to provide information for diagnosis, treatment, or monitoring.
  • Device Description: The description details a laboratory test based on a homogeneous enzyme immunoassay technique performed on automated clinical chemistry analyzers. This further confirms that it is a test performed on biological samples outside of the body.
  • Performance Studies: The performance studies evaluate characteristics relevant to the accuracy and reliability of a laboratory test, such as precision, lower detection limit, and method comparison.

Therefore, based on the provided information, the ONLINE TDM Valproic Acid assay clearly fits the definition of an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The Roche ONLINE TDM Valproic Acid assay was evaluated for several performance characteristics including precision, lower detection limit, method comparison, specificity, and interfering substances. All of the evaluation studies gave acceptable results compared to the predicate device. These experiments provide evidence that the Roche ONLINE TDM Valproic Acid assay is substantially equivalent to the currently marketed Roche COBAS INTEGRA Valproic Acid assay.
