Intended Use / Indications for Use
The Pan Probe Biotech LiveSure™ Barbiturates Screen Test Card and Test Strip devices are rapid in vitro diagnostic (IVD) qualitative lateral flow immuno-chromatographic competitive urinary assays for the detection of Barbiturates (e.g., Secobarbital, Phenobarbital, Phenobarbital, etc.), analogs and metabolites (collectively termed: BAR) in human urine at the NIDA (National Institute on Drug Abuse) modified (Substance Abuse and Mental Health Services Administration) cut-off level of 300 ng BAR/M. The cut-off for both LiveSure™ Test Card and Test Strip device methods has been set at 300 ng BAR drug/ml based upon calibration using Secobarbital as a prototype Barbiturate/BAR drug, and ng BRK drugmit bagod upen vith a GCMS method for the quantitation of all the Secobarbital standard and urine test solutions. These IVD Tests are intended for visual, qualitative screening, for professional use only, and are not intended for quantitative results, nor for over the counter sales. Pan Probe Biotech LiveSure™ BAR Screen Tests for BAR provide only preliminary analytical data. A more specific quantitative alternative method must be used in order to obtain a confirmed analytical result. Both NIDA and SAMHSA have established gas chromatography/mass spectrometry (GC/MS) as a preferred confirmatory method. Clinical considerations and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated.

Device Description
The Pan Probe Biotech LiveSure™ Barbiturates Screen Test Card and Test Strips (i.e., LiveSure™ Barbiturates) devices are rapid qualitative competitive chromatographic IVD immunoassays, in which chemically labeled drug conjugate competes with any Barbiturate (BAR) drugs, analogs or metabolites that may be present in test urinary samples for limited specific antibody binding sites. LiveSure™ Barbiturates 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 against BAR. Each Test Strip and Test Card consists of a membrane absorbent pad having a gold-probe-conjugate pre-labeled with specific monoclonal antibody from mouse that is directed against BAR, and a chromatographic membrane precoated with a chemically modified Barbiturate [Secobarbital] drug-conjugate as a capture reagent. The Test region of each device has been layered with a Barbiturate [Secobarbital] drug-conjugate as a 1" capture region of dail the Process Control region has been pre-coated with a 200 anti-mouse antibody reagent derived from goat. A pink colored antibody-colloidal gold conjugate pad is placed to the right of a test strip. In the absence of BAR drugs, analogs or metabolites in urine, pink colored antibodycolloidal gold conjugates move chromatographically along with a urinary sample on the membrane by capillary action. Antibody-colloidal gold conjugate binds to BAR-drug conjugate, forming an antibodyantigen complex. This antibody-BAR-drug conjugate appears as a second visible pink colored band and as a captured reagent at the test region. Any BAR drugs, analogs or metabolites that are present in a sample urine act as antigens, competing with BAR-drug conjugate at the test band region for limited BAR-antibody binding sites on antibody-colloidal gold conjugate. When a sufficient concentration of urinary BAR drugs, analogs or metabolites are present, these analytes block the limited antibody binding sites. This blockagebinding prevents attachment of pink colored antibody-colloidal gold conjugate at the BAR-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 presence of BAR in urine samples. Thus, negative urine samples produces two pink colored bands, while positive urine samples only one pink colored band.

In-house testing of LiveSure™ Barbiturates Screen Test Strip devices against EMIT® II Assay as a predicate has provided data essentially showing equivalency between these devices and the predicate EMIT® II Assay. Additionally, independent clinical testing of 335 urine samples against LiveSure™ Barbiturates Screen Test Card and Test Strip devices, as well as EMIT® II Assay at an external reference laboratory has resulted in a 100% percent agreement with all GC/MS quantitative positive results.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The subject device was tested against EMIT® II Assay. Independent clinical testing involved 335 urine samples against LiveSure™ Barbiturates Screen Test Card and Test Strip devices, and EMIT® II Assay, at an external reference laboratory. This resulted in a 100% agreement with all GC/MS quantitative positive results. LiveSure™ Barbiturates Test Card or Strip gave a 100% and a 99.6% agreement with GCMS negative results. Comparing both the Test Card positives and Test Strip positives with the EMIT® II positives, a 100% agreement with EMIT® II was obtained with both Test devices. Specificity of the Test Card and Test Strip negatives with EMIT® II negatives was shown to be a 100% and a 99.6%, respectively. In terms of overall accuracy of values at and below the ±25% range of the NIDA/SAMHSA cut-off of 300 ng BAR/ml, the LiveSure™ Barbiturates Screen Test Card and Strip yielded no false positives or FP. Versus GC/MS quantitative BAR data, the LiveSure™ Barbiturates Test Card and Test Strip gave overall accuracy results of 335/335 (100%) and 334/335 (99.7%), respectively, whereas 335/335 (100%) and 334/335 (99.7%) accuracy was obtained with EMIT®II. The LiveSure™ Barbiturates Test Card and Test Strip were determined to be equivalent in performance with each other, and with EMIT®Il assays, as judged against GC/MS results from an independent laboratory.
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
100% percent agreement with all GC/MS quantitative positive results.
100% and a 99.6% agreement with GCMS negative results (for Test Card and Strip respectively).

§ 862.3150 Barbiturate test system.
(a)
Identification. A barbiturate test system is a device intended to measure barbiturates, a class of hypnotic and sedative drugs, in serum, urine, and gastric contents. Measurements obtained by this device are used in the diagnosis and treatment of barbiturate use or overdose and in monitoring levels of barbiturate to ensure appropriate therapy.(b)
Classification. Class II (special controls). A barbiturate 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 Practices guidelines, in vitro diagnostic (IVD) devices for qualitative testing of urine samples for the presence of Barbiturates, analogs, and metabolites in a IVD screening format.
The trade name of the devices are the Pan Probe Biotech LiveSure™ Barbiturates Screen Test Card and The Strip, having a FDA designated common name of Barbiturates Test Systems, and a classification as a rost only, naming a P D P acongreating owith product code: DIS. These IVD devices are intended for medical and forensic screening of urines for Barbiturates, analogs and metabolites.
