The description details a standard immunoturbidimetric assay based on measuring changes in scattered light, which is a well-established chemical/biological principle and does not involve AI or ML. The text explicitly states "Mentions AI, DNN, or ML: Not Found".
No
This device is an in vitro diagnostic test kit used to measure valproic acid levels in serum, which aids in diagnosis and monitoring. It does not directly treat a condition or provide therapy.
Yes
The "Intended Use / Indications for Use" section explicitly states that "Measurements obtained by this device are used in the diagnosis and treatment of valproic acid use or overdose and in monitoring levels of valproic acid to ensure appropriate therapy." This directly indicates its diagnostic purpose.
No
The device is described as an in vitro diagnostic reagent kit, which is a physical product containing chemical components for laboratory testing, not a software-only device.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The document explicitly states, "The Randox Laboratories Ltd. Valproic Acid Test Kit is an in vitro diagnostic reagent for the quantitative determination of valproic acid in serum." It also describes how the measurements are used "in the diagnosis and treatment of valproic acid use or overdose and in monitoring levels of valproic acid to ensure appropriate therapy." This clearly indicates its use for diagnostic purposes outside of the living body.
- Device Description: The description reiterates that it is an "in vitro diagnostic reagent".
- Method: The method described (latex-enhanced immunoturbidimetric assay) is a common technique used in in vitro diagnostics to measure substances in biological samples.
- Sample Type: The test is performed on "serum," which is a biological sample taken from a patient.
All of these points align with the definition of an In Vitro Diagnostic device.

When a sample containing valproic acid is introduced the agglutination reaction is partially inhibited, slowing down the agglutination process. The rate of agglutination is inversely dependent on the concentration of valproic acid in the sample. By aggraination the change in scattered light as a change in absorbance, a concentration curve can montoning the onling in absorbance is inversely proportional to the concentration of valbroic acid in the sample.

§ 862.3645 Neuroleptic drugs radioreceptor assay test system.
(a)
Identification. A neuroleptic drugs radioceptor assay test system is a device intended to measure in serum or plasma the dopamine receptor blocking activity of neuroleptic drugs and their active metabolites. A neuroleptic drug has anti-psychotic action affecting principally psychomotor activity, is generally without hypnotic effects, and is a tranquilizer. Measurements obtained by this device are used to aid in determining whether a patient is taking the prescribed dosage level of such drugs.(b)

Dear Dr. Anderson:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
