Intended Use

The Syva Emit® II Plus Benzodiazepine Assay is a homogeneous enzyme immunoassay with a 200ng/mL or 300ng/mL cutoff. The assay is intended for use in the qualitative and semiquantitative analysis of benzodiazepines in human urine.

Device Story

Homogeneous enzyme immunoassay for benzodiazepine detection in human urine; utilizes lormetazepam as calibrator analyte to increase sensitivity. Operates on automated chemistry analyzers in clinical laboratory settings. Provides qualitative (positive/negative based on 200/300 ng/mL cutoffs) or semiquantitative results. Results are preliminary; require confirmatory testing via GC/MS or similar methods. Clinical judgment required for interpretation of positive results. Benefits include rapid screening for benzodiazepine presence to support clinical decision-making.

Clinical Evidence

Bench testing only. Comparative analysis against predicate showed 97% agreement at 200 ng/mL cutoff and 84% at 300 ng/mL. Spiked sample recovery (40-900 ng/mL) demonstrated 85-118% recovery. Precision studies: qualitative CVs 0.4-1.0%; semiquantitative CVs 1.8-5.6%. Sensitivity limit <15 ng/mL (95% confidence).

Technological Characteristics

Homogeneous enzyme immunoassay. Uses lormetazepam as calibrator analyte. Designed for use on automated chemistry analyzers. Qualitative and semiquantitative modes. Sensitivity <15 ng/mL.

Indications for Use

Indicated for qualitative and semiquantitative analysis of benzodiazepines in human urine. Provides preliminary analytical results; requires confirmation by alternative chemical method (e.g., GC/MS). Intended for use with chemistry analyzers.

Regulatory Classification

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).

### 2. Device Classification Name:

The Clinical Chemistry and Clinical Toxicology Devices Panel have classified "BenzodiazepineTest System" as Class II.

#### 3. Intended Use:

The Syva Emit® II Plus Benzodiazepine Assay is a homogeneous enzyme immunoassay with a 200ng/mL or 300ng/mL cutoff. The assay is intended for use in the qualitative and semiquantitative analysis of benzodiazepines in human urine.

#### 4. Device Description and Characteristics:

This 510(k) Summary of Safety and Effectiveness is being submitted in accordance with the requirements of SMDA 1990.

The Syva Emit® II Plus Benzodiazepine Assay is a homogenous enzyme assay intended for use in the qualitative and semiquantitative analysis of benzodiazepines in human urine.

The Syva Emit® II Plus Benzodiazepine Assay has been found to be equivalent to the predicate device. Syva Emit® II Benzodiazepine Assay with regard to intended use, assay sample, and overall performance characteristics.

Comparative Analysis: The Syva Emit® II Plus Benzodiazepine Assay showed excellent correlation to the predicate method. The comparative analysis to the predicate method resulted in a 97% agreement for the 200ng/mL cutoff and a 84% agreement for the 300ng/mL cutoff. The discordance between the test and predicate method can be explained by the fact that there are different calibrator drugs in the two methods. The calibrators used with the Syva Emit® II Plus Benzodiazepine Assay contain the benzodiazepine, lormetazepam, while the calibrators used with the Syva Emit® II Benzodiazepine Assay contain the benzodiazepine, The use of lormetazepam as the calibrator analyte increases the apparent sensitivity of the Syva Emit® II Plus Benzodiazepine Assay to various benzodiazepines.

## 510(k) SUMMARY OF SAFETY AND EFFECTIVENESS For Syva Emit® Il Plus Benzodiazepine Assay (cont.)

Spiked Sample Recovery: In qualitative spike analysis of lormetazepam in negative human urine specimens, the Syva Emit® II Plus Benzodiazepine Assay using a cutoff of 200 ng/mL and a cutoff of 300 ng/mL correctly identified the spiked specimens containing less than or equal to minus 25% of the respective cutoffs as negative and the spiked specimens containing greater than or equal to plus 25% of the respective cutoffs as positive.

The semiquantitative attribute was assessed by determining the accuracy of recovery for analyte-spiked samples by the Syva Emit® II Plus Benzodiazepine Assay. Negative human urine specimens were spiked with concentrations of lormetazepam at levels throughout the semiguantitative range of 40 to 900 ng/mL. For each known concentration. drug recovery was calculated using the average concentration obtained by the Syva Emit® II Plus Benzodiazepine Assay. Within this range, recovery was within 85-118% of nominal concentrations of spiked analyte.

Precision: A precision study was performed using Syva Emit® II Plus Benzodiazepine Assay in both the qualitative and semiquantitative modes. Acceptable within-run and total precision statistics for both the qualitative and semiguantitative assays were observed.

Qualitative results, determined from rates for controls and cutoff calibrator, demonstrated within-run precision with coefficients of variation (CV) ranging from 0.4 - 0.7% and total precision with CV ranging from 0.7 - 1.0%.

Semiquantitative results, determined from rates for controls and cutoff calibrator, demonstrated within-run precision with CV ranging from 1.8 - 5.2% and total precision with CV ranging from 2.3 - 5.6%.

Sensitivity: The sensitivity level of the Syva Emit® II Plus Benzodiazepine Assay is less than 15 ng/mL. This level represents the lowest concentration of benzodiazepines that can be distinguished from 0 ng/mL with a confidence level of 95%.

#### 5. Substantial Equivalence:

In conclusion, Syva Company -- Dade Behring Inc. considers the Syva Emit® II Plus Benzodiazepine Assay to be substantially equivalent to the Syva Emit® II Benzodiazepine Assay with regard to intended use, assay, sample, and overall performance characteristics,

Device Name: Syva Emit® II Plus Benzodiazepine Assay

#### Indications for Use:

The Syva Emit® II Plus Benzodiazepine Assay is a homogeneous enzyme immunoassay with a 200 ng/mL or 300 ng/mL cutoff. The assay is intended for use in the qualitative and semiquantitative analyses of benzodiazepines in human urine. Syva Emit® II Plus assays are designed for use with a number of chemistry analyzers.

The Syva Emit® II Plus Benzodiazepine Assay provides only a preliminary analytical test result. A more specific alternative chemical method must be used to obtain a confirmed analytical result. Gas chromatography/mass spectrometry (GC/MS) is the preferred confirmatory method. Other chemical confirmation methods are available. Clinical consideration and professional judgment should be applied to any drug-of-abuse test result, particularly when preliminary positive results are used.
