The description details a standard in vitro diagnostic assay based on kinetic interaction of microparticles (KIMS technology) and antibody binding, with no mention of AI or ML.
No.
The device is an in vitro diagnostic test used to detect benzodiazepines in urine, not to treat a condition or disease.
Yes
The "Intended Use / Indications for Use" section explicitly states that this is an "in vitro diagnostic test."
No
The device is an in vitro diagnostic test that relies on chemical reactions and automated clinical chemistry analyzers, which are hardware components. The description focuses on the assay's chemical principles and interaction with physical samples, not solely on software functionality.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The very first sentence explicitly states "Benzodiazepines Plus is an in vitro diagnostic test...".
- Device Description: The description further clarifies that it's an "in vitro diagnostic test".
- Anatomical Site: It analyzes "human urine", which is a biological sample taken from the body.
- Intended User/Care Setting: It's intended for use in "laboratories" on "automated clinical chemistry analyzers", which are typical settings for IVD testing.
All of these points align with the definition of an In Vitro Diagnostic device, which is a medical device intended for use in the in vitro examination of specimens derived from the human body solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to monitor therapeutic measures.

Intended Use / Indications for Use
Benzodiazepines Plus is an in vitro diagnostic test for the qualitative and semi-quantitative detection of benzodiazepines in human urine on automated clinical chemistry analyzers at cutoff concentrations of 100 ng/ml, 200 ng/ml and 300 ng/ml. Semi-quantitative test results may be obtained that permit laboratories to assess assay performance as part of a quality control program.

Device Description
The Roche ONLINE DAT Benzodiazepines Plus assay is an in vitro diagnostic test for the qualitative and semi-quantitative detection of benzodiazepines in human urine on automated clinical chemistry analyzers at cutoff concentrations of 100 ng/ml, 200 ng/ml and 300 ng/ml. Semiquantitative test results may be obtained that permit laboratories to assess assay performance as part of a quality control program.
Principal of procedure
The ONLINE DAT Benzodiazepines Plus assay is based on the kinetic interaction of microparticles in a solution (KIMS technology). Assay measurement is based on measurable changes in light transmission related to the interaction of microparticles in a solution and the sample drug of interest. if present. Benzodiazepine drug derivative is conjugated to microparticles in solution, and benzodiazepine polyclonal antibody (sheep) is solubilized in In the absence of sample drug, free antibody binds to drugbuffer. microparticle conjugates causing the formation of particle aggregates. As the aggregation reaction proceeds in the absence of sample drug, the absorbance increases.
When a urine sample contains the drug in question, this drug competes with the particle-bound drug derivative for free antibody. Antibody bound to sample drug is no longer available to promote particle aggregation, and subsequent particle lattice formation is inhibited. The presence of sample drug diminishes the increasing absorbance in proportion to the concentration of drug in the sample. Sample drug content is determined relative to the value obtained for a known cutoff concentration of drug.
Negative Sample
drug-conjugated microparticles + free antibody = particle aggregates (↑ absorbance)
Positive Sample
sample drug + drug-conjugated microparticle = particle aggregation inhibited drug-conjugated microparticles + free antibody = particle aggregates

§ 862.3170 Benzodiazepine test system.
(a)
Identification. A benzodiazepine test system is a device intended to measure any of the benzodiazepine compounds, sedative and hypnotic drugs, in blood, plasma, and urine. The benzodiazepine compounds include chlordiazepoxide, diazepam, oxazepam, chlorzepate, flurazepam, and nitrazepam. Measurements obtained by this device are used in the diagnosis and treatment of benzodiazepine use or overdose and in monitoring levels of benzodiazepines to ensure appropriate therapy.(b)
Classification. Class II (special controls). A benzodiazepine test system is not exempt if it is intended for any use other than employment or insurance testing or is intended for Federal drug testing programs. The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 862.9, provided the test system is intended for employment and insurance testing and includes a statement in the labeling that the device is intended solely for use in employment and insurance testing, and does not include devices intended for Federal drug testing programs (e.g., programs run by the Substance Abuse and Mental Health Services Administration (SAMHSA), the Department of Transportation (DOT), and the U.S. military).
