Intended Use
Syntron's QuikStrip One Step Barbiturate assay is a rapid, qualitative, competitive binding immunoassay for the determination of Barbiturate in urine at the cutoff level of 200 ng/ml. 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 indicated. 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.
Device Description
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.

No
The device description details a competitive binding immunoassay based on chemical reactions and colorimetric detection, with no mention of computational analysis, algorithms, or learning processes.

No.
The device is an immunoassay for detecting barbiturates in urine, used for screening purposes, not for treating or preventing a disease or condition.

No

Explanation: The device provides preliminary data suggesting the presence of Barbital in urine but states it is "not intended to monitor drug levels, but only to screen urines for the presence of Barbiturate and its metabolites." It explicitly states that results "should be confirmed by other methods," indicating it is a screening tool, not a definitive diagnostic device.

No

The device description clearly outlines a physical chromatographic absorbent device with immobilized antigens and antibodies, indicating it is a hardware-based immunoassay test strip, not software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states it's for the "determination of Barbiturate in urine." This involves testing a sample taken from the human body (urine) in vitro (outside the body) to provide information about a physiological state (presence of Barbiturate).
  • Device Description: The description details a "chromatographic absorbent device" that analyzes the urine sample through a chemical reaction involving antibodies and antigens. This is a typical mechanism for many IVD tests.
  • Performance Studies: The document describes performance studies comparing the device's results to other methods (GC/MS, Emit II) using human urine samples. This is a standard part of demonstrating the performance of an IVD.
  • Reference Device(s): The mention of "Reference Device(s)" like Syva EMIT /200 II and Emit II, which are known IVD drug screening tests, further supports that this device falls into the same category.

The definition of an IVD generally includes devices intended for use in the examination of specimens derived from the human body to provide information for diagnostic, monitoring, or screening purposes. This device fits that description.

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 yielded 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 yielded 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].

§ 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 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].
