Indications for Use
The Nano-Check™ DAT 5 Multi Drug Screening Test for Marijuana, Opiates, Cocaine, Methamphetamine and Phencyclidine is a rapid, self-controlled immunoassay for the qualitative detection of Cannabinoids (THC), Opiates (OPI), Benzoylecgonine (COC), Methamphetamine (mAMP) and Phencyclidine (PCP) compounds and their metabolites in human urine. The detection limits (cut-off concentrations) of this test are as follows: Cannabinoids at 50 ng/ml, Opiates at 2000 ng/ml, Cocaine at 300 ng/ml, Methamphetamine at 1000 ng/ml and Phencyclidine at 25 ng/ml. This assay is intended for Professional and Laboratory In-Vitro Use Only.
Device Story
Single-use cassette-based lateral flow immunoassay; detects Cannabinoids, Opiates, Cocaine, Methamphetamine, and Phencyclidine in human urine. Operator adds urine sample to cassette well; sample migrates through test strip via capillary action. Competitive binding mechanism: drug in sample competes with drug-labeled conjugate for antibody binding sites. Absence of line at test area indicates positive result; presence of line indicates negative result. Internal process control confirms adequate sample volume and strip integrity. Visually read by professional/laboratory personnel. Provides preliminary analytical results; requires confirmatory testing (e.g., GC/MS) for clinical decision-making. Benefits include rapid screening for drugs of abuse in professional settings.
Clinical Evidence
No clinical data. Substantial equivalence supported by analytical performance studies including precision/reproducibility, detection limits, analytical specificity, and method comparison studies against predicate devices.
Technological Characteristics
Lateral-flow immunochromatographic assay; competitive binding principle. Membrane strip with immobilized antibodies/drug-conjugates; gold colloidal particle indicator. Single-use plastic cassette housing. Sample application via disposable dropper. Qualitative visual readout. No electronic components or software.
Indications for Use
Indicated for professional/laboratory in-vitro qualitative detection of Cannabinoids (THC), Opiates (OPI), Benzoylecgonine (COC), Methamphetamine (mAMP), and Phencyclidine (PCP) and their metabolites in human urine. Cut-offs: THC 50ng/ml, OPI 2000ng/ml, COC 300ng/ml, mAMP 1000ng/ml, PCP 25ng/ml.
Regulatory Classification
Identification
A cannabinoid test system is a device intended to measure any of the cannabinoids, hallucinogenic compounds endogenous to marihuana, in serum, plasma, saliva, and urine. Cannabinoid compounds include delta-9-tetrahydrocannabinol, cannabidiol, cannabinol, and cannabichromene. Measurements obtained by this device are used in the diagnosis and treatment of cannabinoid use or abuse and in monitoring levels of cannabinoids during clinical investigational use.
Special Controls
*Classification.* Class II (special controls). A cannabinoid 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).

3. **Special condition for use statement(s):**
The Nano-Check™ DAT 5 Multi Drug Screening Test provides only a preliminary analytical test result. A more specific alternative chemical method must be used to obtain a confirmed analytical result. Gas chromatography/Mass spectrometry is the preferred confirmatory method. Other chemical confirmation methods are available. Clinical consideration and professional judgment should be applied to any drug of abuse test result, particularly when preliminary positive results are used.
The assay is not designated for use in point-of-care settings.
Tests for opiates cannot distinguish between abused drugs and certain prescribed medications.
Certain foods or medications may interfere with tests for amphetamines and opiates and cause false positive results.

K. Standard/Guidance Document Referenced (if applicable):
The sponsor referenced the following guidance document(s) in their submission:

L. Test Principle:
The test employs lateral flow immunochromatographic technology.
Drug in the sample and drug-labeled conjugate (containing a chromagen) compete for antibody binding sites in the test area of the test strip. Binding of drug in the sample causes the absence of a line at the test area, i.e., a positive result. When drug is not present in the sample, the drug-labeled conjugate binds at the test line, resulting in formation of a line, i.e., a negative result. The absence or presence of the line is determined visually by the operator.
The device also has an internal process control which indicates that an adequate volume of sample has been added and that the immunochromatographic strip is intact.
M. Performance Characteristics (if/when applicable):
1. Analytical performance:
a. Precision/Reproducibility:
Drug free samples were spiked with the five drugs to achieve the concentration of either -50% cutoff or +50% cutoff levels. Ten samples, each containing a different set of concentration combinations for the 5 drugs and blind -labeled samples, were tested on duplicated devices by three operators. All tests that applied the +50% cutoff urine sample were detected positive by all three operators, and all tests of -50% cutoff urine samples were detected negative by all three operators. Results of study presented below.

c. Traceability (controls, calibrators, or method):
Control materials are required but are not specifically identified in the labeling.
The device has an internal process control. Users are instructed to follow federal, state, and local guidelines when determining when to run external controls.
Stability studies are summarized for the controls. The sponsor specifies the concentrations of materials evaluated in the studies, the frequency of testing, the method for testing the materials, environmental conditions of storage, and acceptance criteria for the study. Accelerated studies are being used by the sponsor to estimate the expiration date; however, on-going real time studies are being performed.
