Intended Use

Bionike's AQ™ Phencyclidine (PCP) assay is a rapid, qualitative, competitive binding immunoassay for the determination of Phencyclidine (PCP) in urine at the cutoff level of 25 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". Bionike Laboratories' AQ™ Phencyclidine (PCP) Test is not intended to monitor drug levels, but only to screen urines for the presence of Phencyclidine (PCP) and its metabolites.

Device Story

Bionike AQ™ Phencyclidine (PCP) Test is a chromatographic absorbent immunoassay for urine drug screening. Input: urine sample. Principle: competitive binding; drug/metabolites in sample compete with immobilized drug conjugate on a porous membrane for limited antibody sites. Labeled antibody-dye conjugate binds to free drug, forming antibody-antigen complex. If drug concentration exceeds 25 ng/ml, complex competes with immobilized antigen, preventing magenta band formation in positive reaction zone. Control zone binds unbound dye to confirm test validity. Used in clinical/forensic settings; operated by laboratory personnel. Output: visual magenta band (qualitative). Results are preliminary; require GC/MS confirmation. Assists clinicians in identifying potential PCP presence to guide further diagnostic or forensic decision-making.

Clinical Evidence

Clinical trial of 286 urine samples compared Bionike AQ™ PCP Test to Emit II® (25 ng/ml cutoff) with GC/MS confirmation. Results showed 100% relative sensitivity, 100% relative specificity, and 100% accuracy. Two false positives occurred in both methods for samples containing PCP between 20-25 ng/ml (below cutoff). No false negatives were reported.

Technological Characteristics

Chromatographic absorbent device; porous membrane support; competitive binding immunoassay. Qualitative visual readout. No electronic components, software, or external energy source required. Materials include immobilized drug conjugate and labeled antibody-dye conjugate.

Indications for Use

Indicated for the qualitative screening of urine for Phencyclidine (PCP) and its metabolites in individuals suspected of drug use. Intended for medical/forensic screening at a 25 ng/ml cutoff. Not for monitoring drug levels.

Predicate Devices

• Syva EMIT® II (25 ng/ml)

## Summary of Safety and Effectiveness

The sponsor, Bionike Laboratories, Inc. (1015 Grandview Drive, South San Francisco. CA 94080-4910), has developed, manufactured, and tested under GMP/GLP guidelines a device for the qualitative testing of urine for the presence of Phencyclidine (PCP) and its metabolites in a screening format.

The trade name of the device is Bionike AQ™ Phencyclidine (PCP) Test having a designated common name of Phencyclidine (PCP) Test System and a classification as a Class II device per FDA. This device is intended for the medical/forensic screening of urine.

Bionike Laboratories' AQ™ Phencyclidine (PCP) 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 25 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 Bionike AQ™ Phencyclidine (PCP) 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 Syya EMIT® (25) II on samples documented to be positive by GC/MS. A clinical trial consisting of 286 samples was run and the combined data vielded a relative sensitivity of 100%, a relative specificity of 100% with an accuracy of 100% when compared to Emit II® run at 25 ng/ml. Non parametric testing failed to demonstrate any significant difference from one another. Both Emit II and Bionike AQ™ PCP yielded 2 false positives due to the presence of Phencyclidine (PCP) at levels below 25 ng/ml, but above 20 ng/ml as determined by GC/MS.

All samples by either screening method were confirmed by GC/MS (25 nemi. The testing performed by the Clinical Trial site did find 2 false positives but no false negatives in the samples tested. The false positives were due to the presence of phencyclidine (PCP) between 20 and 25 ng/ml by GC/MS.

Dear Dr. Barquest:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
