FEB | 2 |998 Page 25 of 68 Revision A 8/18/97 Printed on 12/12/97 ## SUMMARY OF SAFETY AND EFFECTIVENESS 8. The sponsor, Syntron Bioresearch, Inc. (2774 Loker Ave. West, Carlsbad, California, 92008), has developed, manufactured, and tested under GMP/GLP guidelines a device for the qualitative testing of urine for the presence of Barbiturate and its metabolites in a screening format. The trade name of the device is QuikStrip One Step Barbiturate Test having a designated common name of Barbiturate Test System and a classification as a Class II device per 21 CFR 9 862.3150. This device is intended for the medical/forensic screening of urine. Syntron's QuikStrip One Step Barbiturate Test consists of a chromatographic absorbent device in which the drug or drug metabolites in the sample compete with a drug conjugate immobilized on a porous membrane support for the limited antibody sites. As the test sample flows up through the absorbent device. the labeled antibody-dye conjugate binds to the free drug in the specimen forming an antibody:antigen complex. This complex competes with immobilized antigen conjugate in the positive reaction zone and will not produce a magenta color band when the drug is above the detection level of 200 ng/ml. Unbound dye conjugate binds to the reagent in the control zone. producing a magenta color band, demonstrating that the reagents and device are functioning correctly. In-house testing of Syntron's QuikStrip One Step Barbiturate Test yielded a relative sensitivity or agreement within positive samples of 1.000 and relative specificity or agreement within negative samples of 1.000 and an accuracy of 100% when tested against Syva EMIT® /200 II on samples documented to be positive by GC/MS. A clinical trial consisting of 307 samples was run and the combined data vielded a relative sensitivity of 100%, a relative specificity of 99.41% with an accuracy of 99.61% when compared to Emit II® run at 200 ng/ml. By non parametric testing the results are not significantly different from one another. QuikStrip vielded 2 false positives due to the presence of an adulterant "Clean Jane" (sodium dodecylsulfate [Tide]). All positive samples by either screening method were confirmed by GC/MS (200 neml) . The testing performed by both the sponsor and the Clinical Trial site did find 2 false positives and no false negatives in the samples tested. The False Positive was due to the presence of "Clean Jane" (sodium dodecylsulfate (Tidel). GC/MS confirmed the presence of sodium dodecylsulfate [Tide].

The test provides only preliminary data which should be confirmed by other methods such as gas chromatography/mass spectrophotometry (GC/MS). Clinical considerations and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are indicated6. Syntron's QuikStrip One Step Barbiturate Test is not intended to monitor drug levels, but only to screen urines for the presence of Barbiturate and its metabolites.
