No
The device description details a standard immunoassay based on competitive binding, and there is no mention of AI or ML in the intended use, device description, or performance studies.
No
The device is described as an immunoassay for determining the presence of Phencyclidine (PCP) in urine, providing preliminary screening data rather than being used for treatment or therapy.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the device is for "the determination of Phencyclidine (PCP) in urine" and "to screen urines for the presence of Phencyclidine (PCP) and its metabolites." This indicates a diagnostic purpose.
No
The device description clearly describes a physical chromatographic absorbent device, which is a hardware component, not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "determination of Phencyclidine (PCP) 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 PCP).
- Device Description: The device is a "chromatographic absorbent device" that performs a "competitive binding immunoassay". This is a common method used in IVD tests to detect specific substances in biological samples.
- Sample Type: The test is performed on "urine", which is a biological specimen.
- Purpose: The test is used to "screen urines for the presence of Phencyclidine (PCP) and its metabolites". This is a diagnostic purpose, even though it provides preliminary data.
The description clearly aligns with the definition of an In Vitro Diagnostic device, which is used to examine specimens derived from the human body to provide information for diagnostic purposes.

Intended Use / Indications for Use
Syntron's QuikStrip One Step 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 indicated6. Syntron's QuikStrip One Step 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 Description
Syntron's QuikStrip One Step 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 Syntron's QuikStrip One Step Phencyclidine (PCP) Test vielded 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® (25) II on samples documented to be positive by GC/MS. A clinical trial consisting of 286 samples was run and the combined data yielded 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. By non parametric testing the results are not significantly different from one another. Both Emit II and QuikStrip vielded 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.
Summary of Performance Studies
In-house testing: relative sensitivity 1.000, relative specificity 1.000, accuracy 100% against Syva EMIT® (25) II on GC/MS confirmed positive samples. Clinical trial: 286 samples, relative sensitivity 100%, relative specificity 100%, accuracy 100% compared to Emit II® run at 25 ng/ml. Non-parametric testing showed no significant difference. Both Emit II and QuikStrip yielded 2 false positives (PCP between 20-25 ng/ml by GC/MS). All positive samples by either screening method were confirmed by GC/MS (25 ng/ml). The clinical trial found 2 false positives and no false negatives.
Key Metrics
Relative sensitivity or agreement within positive samples of 1.000, relative specificity or agreement within negative samples of 1.000, accuracy of 100%. Clinical trial data: relative sensitivity of 100%, a relative specificity of 100% with an accuracy of 100%.

Summary of Safety and Effectiveness
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 Phencyclidine (PCP) and its metabolites in a screening format.
The trade name of the device is QuikStrip One Step 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.
Syntron's QuikStrip One Step 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.

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