## Indications for Use

The LZI Multiple Analyte Set A, B, and C Urine Drugs of Abuse Calibrators are intended for in vitro diagnostic use for the calibration of assays for the analytes currently listed in the package insert: Benzoylecgonine, Methamphetamine, Methadone, 6-acetylmorphine, MDMA, Morphine, Oxazepam, and Secobarbital. The calibrators are designed for prescription use with homogeneous enzyme immunoassays on automated clinical chemistry analyzers. The LZI Multiple Analyte Set A, B, and C Urine Drugs of Abuse Controls are intended for in vitro diagnostic use to monitor the performance of assays for the analytes currently listed in the package insert: Benzoylecgonine, Methamphetamine, Methadone, 6-acetylmorphine, MDMA, Morphine, Oxazepam, and Secobarbital. The controls are designed for prescription use with homogeneous enzyme immunoassays on automated clinical chemistry analyzers.

## Device Story

Device consists of liquid, ready-to-use calibrators and controls for drugs of abuse testing. Input: processed, drug-free human urine matrix spiked with known concentrations of specific drug analytes. Operation: used by laboratory technicians on automated clinical chemistry analyzers to calibrate assays and monitor performance. Output: calibration curves and quality control results used by clinicians to verify assay accuracy. Clinical context: preliminary analytical results; requires confirmation by GC/MS or LC/MS. Benefit: ensures accuracy and reliability of drug screening assays, supporting clinical decision-making in toxicology.

## Clinical Evidence

Bench testing only. Stability studies conducted at 2-8°C, room temperature, and 30°C; results showed <10% variation. Real-time stability confirmed for at least 12 months at 2-8°C. Value assignment verified gravimetrically using NIST-traceable weights and confirmed by GC/MS to be within ±10% of target concentrations.

## Technological Characteristics

Liquid, ready-to-use human urine matrix containing drug analytes and 0.09% sodium azide preservative. Analyte concentrations verified by GC/MS. Storage at 2-8°C. Compatible with automated clinical chemistry analyzers using homogeneous enzyme immunoassay technology.

## Regulatory Identification

A clinical toxicology calibrator is a device intended for medical purposes for use in a test system to establish points of reference that are used in the determination of values in the measurement of substances in human specimens. A clinical toxicology calibrator can be a mixture of drugs or a specific material for a particular drug (e.g., ethanol, lidocaine, etc.). (See also § 862.2 in this part.)

## Special Controls

*Classification.* Class II (special controls). 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.
