Intended Use
The Benzodiazepines assay is used for the qualitative analysis of benzodiazepines in human urine with a cutoff of 200 ng/mL. For use in clinical laboratories. Measurements obtained by this device are used in the diagnosis of benzodiazepines use or overdose. The Benzodiazepines assay is calibrated with lormetazepam and will detect a variety of benzodiazepines and their metabolites. The Benzodiazepines assay provides only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GCMS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
Device Description
The Benzodiazepines assay is an in vitro diagnostic assay for the qualitative analysis of benzodiazepines in human urine. The assay is a homogeneous enzyme immunoassay with a 200 ng/mL cutoff. The assay is based on competition between drug in the specimen and drug labeled with the enzyme glucose-6-phosphate dehydrogenase (G6PDH) for antibody binding sites. Enzyme activity can be measured in terms of enzyme activity. Active enzyme concentration in the specimen can be measured in decreases upon binding to the antibody, so the drug converted D to NADH, resulting in an absorbance change that can be measured spectrophotometrically.
More Information

No
The description details a standard enzyme immunoassay for detecting benzodiazepines in urine. There is no mention of AI, ML, image processing, or any other technology typically associated with AI/ML in medical devices. The performance studies are standard analytical comparisons, not AI/ML model validation.

No.
This device is an in vitro diagnostic assay used for qualitative analysis of benzodiazepines in human urine, which helps in diagnosing benzodiazepine use or overdose, rather than treating a condition.

Yes

The "Intended Use / Indications for Use" section explicitly states, "Measurements obtained by this device are used in the diagnosis of benzodiazepines use or overdose." This clearly indicates its diagnostic purpose.

No

The device description clearly states it is an "in vitro diagnostic assay" and describes a "homogeneous enzyme immunoassay" based on chemical reactions and spectrophotometric measurement, indicating it is a physical kit or reagent, not 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 qualitative analysis of benzodiazepines in human urine and that the measurements are used in the diagnosis of benzodiazepines use or overdose. This clearly indicates a diagnostic purpose.
  • Device Description: The "Device Description" section describes the assay as an "in vitro diagnostic assay for the qualitative analysis of benzodiazepines in human urine." This directly labels the device as an IVD.
  • Sample Type: The device analyzes human urine, which is a biological specimen. IVDs are designed to test biological specimens.
  • Care Setting: The intended user is "clinical laboratories," which is a typical setting for the use of IVD devices.

All of these points align with the definition of an In Vitro Diagnostic device.

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

Comparative performance studies were conducted using the AEROSET® System. The Benzodiazepines assay method comparison yielded acceptable correlation with the Emit II Benzodiazepine assay on the SYVA-30R Analyzer. The concordance table shows: 99% agreement. The Benzodiazepines assay method comparison yielded acceptable correlation with GC/MS. The concordance table shows 87% agreement with GCMS. The clinical specimens tested ranged from 57.5 to 13,174.0 ng/mL. Precision studies were conducted using the Benzodiazepines assay. A within-run and total precision study was performed using five levels of material.

Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)

The total %CV for Verifier I is 1.36%. The total %CV for the Cutoff Calibrator is 1.48%. The total %CV for Verifier II is 1.10%. The total %CV for the -25% Control of Cutoff Calibrator and the +25% Control of Cutoff Calibrator samples are 1.92% and 1.60% respectively. The Benzodiazepines cutoff is 200 ng/mL. The limit of detection (sensitivity) of the Benzodiazepines assay is 15 ng/mL.

§ 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).
