Single Analyte Urine Drugs of Abuse Calibrators and Controls are substantially equivalent to the Drugs of Abuse Urine Calibrators and Controls (Diagnostic Reagents, Inc., now Microgenics Corporation), cleared under premarket notification K983159. {1}------------------------------------------------ # Device Description All of the Single Analyte Urine DAU Calibrators and Controls are human urine-based liquid, and ready to use. These Calibrators and Controls do not have any especially unique technical characteristics. When applicable, they contain known concentration of a specific drug analyte. The Negative DAU Calibrator is a processed, drug-free human urine matrix. The Low, Cutoff, Intermediate, and High Calibrators, as well as the 2 levels of Controls are prepared by spiking known concentrations of drug analyte into the Negative DAU Calibrator matrix. The various concentrations of each drug analyte in their corresponding calibrators and controls are summarized as follows: | | Phencyclidine EIA | Opiate EIA | Cocaine Metabolite EIA | Amphetamines EIA | |-------------------------|-------------------|------------|------------------------|-------------------| | Reference Material | Phencyclidine | Morphine | Benzoylecgonine | d-Methamphetamine | | Low Calibrator | 12.5 ng/mL | 150 ng/mL | 150 ng/mL | 500 ng/mL | | Cutoff Calibrator | 25 ng/mL | 300 ng/mL | 300 ng/mL | 1000 ng/mL | | Intermediate Calibrator | 50 ng/mL | 600 ng/mL | 1000 ng/mL | 1500 ng/mL | | High Calibrator | 100 ng/mL | 1000 ng/mL | 3000 ng/mL | 2000 ng/mL | | Control Level 1 | 18 ng/mL | 225 ng/mL | 225 ng/mL | 750 ng/mL | | Control Level 2 | 32 ng/mL | 375 ng/mL | 375 ng/mL | 1250 ng/mL | The nominal concentrations of the analyte in the calibrators and controls are determined and confirmed by GC/MS. # Intended Use The Single Analyte Urine Drugs of Abuse (DAU) Calibrators are intended for in vitro diagnostic use for the calibration of their respective DAU enzyme immunoassays to detect phencyclidine, opiates, cocaine metabolite, or amphetamines in human urine. The Single Analyte Urine Drugs of Abuse (DAU) Controls are intended for in vitro diagnostic use for the validation of their respective DAU enzyme immunoassays to detect phencyclidine, opiates, cocaine metabolite, or amphetamines in human urine. ## Comparison to Predicate Device LZI's Single Analyte Urine DAU Calibrators and Controls are similar in intended use, matrix, and performance to the DRI's Drugs of Abuse Urine Calibrators and Controls. Similarities: - Both are for the calibration and validation of DAU enzyme immunoassays to detect the . same commonly abused drug analytes (phencyclidine, opiates, cocaine metabolite, or amphetamines) in human urine. {2}------------------------------------------------ - The cutoff concentration for each analyte is the same per recommendations of The . Substance Abuse and Mental Health Services Administration (SAMHSA). - Both use 2 levels of Controls, and the concentrations are set at equal to or approximately . ± 25% of the cutoff concentration for each analyte according to the SAMHSA guideline. - The nominal concentrations of the analyte in the calibrators and controls are determined . and confirmed by GC/MS. - . Both are urine-based liquids. - . Storage condition is the same, at 2℃ to 8℃. - Performance characteristics on precision, accuracy and stability are similar. � | Characteristics | DRI's DAU Urine<br>Calibrators and Controls | LZI's Single Analyte Urine<br>DAU Calibrators and Controls | |--------------------------------------------------|--------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------| | No. of Analytes in each<br>Calibrator or Control | All 4 drugs in each Calibrator or Control | Single drug only in each<br>Calibrator or Control. | | No. of Calibrators | 3 levels* including the<br>Negative Calibrator. | 5 levels including the Negative<br>Calibrator | | Nomenclature/Labeling<br>of Calibrators | Negative, Low (= Cutoff),<br>and High | Negative, Low, Cutoff,<br>Intermediate, and High | | Concentration of<br>Analyte(s) | Phencyclidine Controls: 20<br>and 35 ng/mL<br>Cocaine High Calibrator:<br>1000 ng/mL | Phencyclidine Controls: 18 and<br>32 ng/mL,<br>Cocaine High Calibrator: 3000<br>ng/mL | Differences: * Additional calibrators are now available. Currently 5 levels of calibrators (Cal 0, 1, 2, 3, and 4) are available from DRI/Microgenics Corp. (under "Multi-drug Urine Calibrators and Controls" product name). # Conclusion The information provided in the premarket notification demonstrates that the LZI's Single Analyte Urine Drugs of Abuse Calibrators and Controls are substantially equivalent to previously approved predicate devices, notably the DRI's DAU Urine Calibrators and Controls, and safe and effective for its intended use. {3}------------------------------------------------ DEPARTMENT OF HEALTH & HUMAN SERVICES Image /page/3/Picture/1 description: The image shows a logo for the Department of Health & Human Services U.S.A.
