Device Description
The Pan Probe Biotech LiveSure™ Benzodiazepines Screen Test Card and Test Strip (i.e., LiveSure™ Benzodiazepines) devices are rapid qualitative competitive chromatographic IVD immunoassays, in which Donzoally labeled drug conjugate competes with any Benzodiazepine (BZD) drugs, analogs or metabolites that may be present in test urine samples for limited specific antibody binding sites. I liveSure™ Benzodiazepines devices have a unique membrane pre-coated with a gold conjugate immunoassay indicator that is used is pre-labeled with specific monoclonal antibody from mouse directed imministed on the strip and Test Card consists of a membrane absorbent pad having a goldarobe-conjugate pre-labeled with specific monoclonal antibody from mouse that is directed against BZD drugs, and a chromatographic membrane pre-coated with a chemically modified Benzodiazepine (Oxazepam) drug-conjugate as a capture reagent. The Test region of each device has been layered with a Benzodiazepine [Oxazepam] drug-conjugate as a 1 capture reagent, while the Process Control region has been pre-coated with a 200 anti-mouse antibody reagent derived from goat. A pink colored anti-BZD monoconal antibody-colloidal gold conjugate pad is placed to the right of a test strip. In the absence of BZD drugs, analogs or metabolites in urine, pink colored antibody-colloidal gold conjugates move chromatographically along with the urinary samples on the membrane by capillary action. Antibodycolloidal gold conjugate binds to BZD-drug conjugate, forming an antibody-antigen complex. This antibody-BZD-drug conjugate appears as second visible pink colored band and captured reagent at the test region. Any BZD drugs, analogs or metabolites that are present in a sample urine act as antigens, competing with BZD-drug conjugate at the test band region for limited BZD-antibody binding sites on antibody-colloidal gold conjugate. When a sufficient concentration of urinary BZD drugs, analogs or metabolites are present, these analytes block the limited antibody binding sites. This blockage-binding prevents attachment of pink colored antibody-colloidal gold conjugate at the BZD-drug conjugate zone located at the test band region. To serve as a procedural control, a pink colored band in a control region will always appear, regardless of the presence of BZD in urine samples. Thus, negative urine samples produces two pink colored bands, while positive urine samples produce only one pink colored band.

(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).

SUMMARY STATEMENT OF SAFETY AND EFFECTIVENESS
The sponsor, Pan Probe Biotech, Inc., has developed, manufactured, and tested under Good Laboratory The openod, I an Frob diagnostic (IVD) devices for qualitative testing of urine samples for the presence of Benzodiazepines, analogs, and metabolites in an IVD screening format.
phesinde name of the devices are the Pan Probe Biotech LiveSure™ Benzodiazepines Screen Test Card The Trade Thame of the de noor and of Benzodiazepines Test Systems, and a classification as and rost billp; framig a PPR 862.3170, with product code: JXM. These IVD devices are intended for medical/forensic screening of urines for Benzodiazepines, analogs, and metabolites.
The Pan Probe Biotech LiveSure™ Benzodiazepines Screen Test Card and Test Strip (i.e., LiveSure™ The Fair - robes) devices are rapid qualitative competitive chromatographic IVD immunoassays, in which Donzoally labeled drug conjugate competes with any Benzodiazepine (BZD) drugs, analogs or metabolites that may be present in test urine samples for limited specific antibody binding sites. I liveSure™ Benzodiazepines devices have a unique membrane pre-coated with a gold conjugate immunoassay indicator that is used is pre-labeled with specific monoclonal antibody from mouse directed imministed on the strip and Test Card consists of a membrane absorbent pad having a goldarobe-conjugate pre-labeled with specific monoclonal antibody from mouse that is directed against BZD drugs, and a chromatographic membrane pre-coated with a chemically modified Benzodiazepine (Oxazepam) drug-conjugate as a capture reagent. The Test region of each device has been layered with a Benzodiazepine [Oxazepam] drug-conjugate as a 1* capture reagent, while the Process Control region has been pre-coated with a 200 anti-mouse antibody reagent derived from goat. A pink colored anti-BZD monoconal antibody-colloidal gold conjugate pad is placed to the right of a test strip. In the absence of BZD drugs, analogs or metabolites in urine, pink colored antibody-colloidal gold conjugates move chromatographically along with the urinary samples on the membrane by capillary action. Antibodycolloidal gold conjugate binds to BZD-drug conjugate, forming an antibody-antigen complex. This antibody-BZD-drug conjugate appears as second visible pink colored band and captured reagent at the test region. Any BZD drugs, analogs or metabolites that are present in a sample urine act as antigens, competing with BZD-drug conjugate at the test band region for limited BZD-antibody binding sites on antibody-colloidal gold conjugate. When a sufficient concentration of urinary BZD drugs, analogs or metabolites are present, these analytes block the limited antibody binding sites. This blockage-binding prevents attachment of pink colored antibody-colloidal gold conjugate at the BZD-drug conjugate zone located at the test band region. To serve as a procedural control, a pink colored band in a control region will always appear, regardless of the presence of BZD in urine samples. Thus, negative urine samples produces two pink colored bands, while positive urine samples produce only one pink colored band.
In-house testing of LiveSure™ Benzodiazepines Screen Test Card and Test Strip devices against EMIT® II Assay as a predicate device provided data essentially showing equivalency between these devices and the predicate EMIT® II Assay. Additionally, independent clinical testing of 387 urine samples against LiveSure™ Benzodiazepines Screen Test Card and Test Strip devices, as well as EMIT® II Assay at an external reference laboratory resulted in a 100% percent with all GC/MS quantitative positive results. Moreover, LiveSure™ Benzodiazepines Test Card or Strip gave both 99.3% agreement with GC/MS negative results. In comparing the Test Card and Test Strip positives with EMIT® II positives, both 98.3% respective agreement with EMIT® II was found. Specificity of Test Card and Test Strip negatives with EMIT® II negatives was shown to be 99.5%, respectively. In terms of overall accuracy of values at and below the ±25% range of the NIDA/SAMHSA cut-off of 300 ng/ml of Benzodiazepines, however, the LiveSure™ Benzodiazepines Screen Test Card and Strip yielded no false positives or no FP, but EMIT®Il resulted in 1 FP values for urine samples with GC/MS results below ng/ml. Finally, the LiveSure™ Benzodiazepines Test Card and the Test Strip gave overall accuracy results of 385/387(99.5%) for both, versus GC/MS data, whereas 385/387(99.5%) accuracy was obtained with EMIT®II. Thus, as judged against GC/MS results from an independent laboratory, the LiveSure™ Benzodiazepines Test Card and Test Strip were determined to be equivalent in performance to each other and somewhat superior in capability versus assays with EMIT®II.
