## Indications for Use

The OTI Benzodiazepines Intercept® MICRO-PLATE EIA is intended for use by clinical laboratories in the qualitative determination of benzodiazepines in oral fluid collected with the Intercept® Oral Fluid Drug Test Oral Specimen Collection Device using a 1.0 ng/mL(nordiazepine) cutoff. For In Vitro Diagnostic Use. The OTI Benzodiazepines Intercept® MICRO-PLATE EIA provides only a preliminary analytical test result. A more specific alternative chemical method should be used in order to obtain a Gas chromatography/mass spectrometry/mass spectrometry confirmed analytical result. (GC/MS/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drugs of abuse test result, particularly when a preliminary, positive result is observed.

## Device Story

The OTI Benzodiazepines Intercept® MICRO-PLATE EIA is a competitive micro-plate immunoassay used in clinical laboratories to detect benzodiazepines in oral fluid. The device utilizes the Intercept® Oral Fluid Drug Test Oral Specimen Collection Device for sample acquisition. During the assay, the oral fluid specimen and an enzyme-labeled hapten derivative are added to an EIA well containing fixed antibodies. A competitive binding process occurs between the drug in the specimen and the enzyme-labeled hapten for the antibody binding sites. After washing, a substrate is added to produce color. The absorbance at 450 nm is measured; the intensity is inversely proportional to the concentration of benzodiazepines in the specimen. The output is a preliminary qualitative result. Healthcare providers use this result as a screening tool, which must be followed by a more specific confirmatory method, such as GC/MS/MS, before making clinical decisions. The device assists in identifying potential benzodiazepine presence, supporting clinical judgment in drug abuse testing.

## Clinical Evidence

Clinical accuracy was evaluated across three population studies with 149 total specimens. Performance was compared against GC/MS/MS as the reference method. Results showed the device effectively distinguishes between positive and negative samples at the 1.0 ng/mL cutoff. Precision studies reported intra-assay CVs of 4.9-6.5% and inter-assay CVs of 7.6-11.4%.

## Technological Characteristics

Solid-phase competitive enzyme immunoassay. Uses micro-plate format with antibody-coated wells. Sensing principle is colorimetric absorbance measurement at 450 nm. The system is designed for use with the Intercept® Oral Fluid Drug Test Oral Specimen Collection Device. No specific materials or software algorithm classes are detailed beyond standard immunoassay reagents.

## Regulatory 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.

## Special Controls

*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).

#### Principle of the Assay

The OT1 Benzodiazepines Intercept® MICRO-PLATE EIA is a competitive micro-plate immunoassay for the detection of benzodiazepines in oral fluid collected with the Intercept® Oral Fluid Drug Test Oral Specimen Collection Device. Specimen or standard is added to an EIA well in combination with an enzyme-labeled hapten derivative. In an ELA well containing an oral fluid specimen positive for benzodiazepines, there is a competition between the drug and the enzymelabeled hapten to bind the antibody fixed onto the EIA wells are then washed, substrate is added, and color is produced. The absorbance measured for each well at 450 mm is inversely proportional to the amount of benzodiazepines present in the specimen or calibrator/control. Because currently there are no SAMHSA assigned cutoffs for benzodiazepines testing using oral fluid, OTI recommends a cutoff of 1.0 ng/mL when testing oral fluid collected with the Intercept® Oral Fluid Drug Test Oral Specimen Collection Device. This cutoff is within the limit of detection by the OTI Benzodiazepines Intercept® MICRO-PLATE EIA.

#### న్. Intended Use Statement:

The OTI Benzodiazepines Intercept® MICRO-PLATE EIA is intended for use by clinical laboratories in the qualitative determination of benzodiazepines in oral fluid collected with the Intercept® Oral Fluid Drug Test Oral Specimen Collection Device using a 1.0 ng/mL(nordiazepine) cutoff. For In Vitro Diagnostic Use.

The OTI Benzodiazepines Intercept® MICRO-PLATE EIA provides only a preliminary analytical test result. A more specific alternative chemical method should be used in order to obtain a Gas chromatography/mass spectrometry/mass spectrometry confirmed analytical result. (GC/MS/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drugs of abuse test result, particularly when a preliminary, positive result is observed.
