Device Story

Lateral flow immunochromatographic assay for qualitative drug screening in human urine. Device consists of test strips integrated into plastic dipcard; absorbent end contacts urine sample. Principle: competitive immunoassay; drug in sample competes with drug-protein conjugate for limited monoclonal antibody binding sites. Negative result: colored line in Test Region (T) indicates drug below detection level. Positive result: absence of line in Test Region (T) indicates drug at or above detection level. Control line (C) confirms proper test performance. Used in clinical or home settings; operated by healthcare professionals or lay users. Provides preliminary results; requires professional judgment and confirmatory testing (GC/MS or LC/MS) for clinical decision-making.

Clinical Evidence

Bench testing only. Precision/reproducibility studies performed across 25 days using three lots. Analytical specificity/cross-reactivity evaluated against numerous compounds. Method comparison study performed with 80 clinical samples per drug compared to LC/MS. Lay user study conducted with 280 participants across three sites using various drug concentrations confirmed by LC/MS, demonstrating high accuracy.

Technological Characteristics

Lateral flow immunochromatographic assay. Materials: plastic dipcard with integrated test strips. Principle: competitive binding. Energy source: none (capillary action). Connectivity: none. Sterilization: not stated. Software: none.

Indications for Use

Indicated for qualitative detection of single or multiple drugs of abuse in human urine. Intended for prescription (Rx) or over-the-counter (OTC) use. Provides preliminary results; requires confirmatory testing (GC/MS or LC/MS).

Regulatory Classification

Identification

An opiate test system is a device intended to measure any of the addictive narcotic pain-relieving opiate drugs in blood, serum, urine, gastric contents, and saliva. An opiate is any natural or synthetic drug that has morphine-like pharmocological actions. The opiates include drugs such as morphine, morphine glucoronide, heroin, codeine, nalorphine, and meperedine. Measurements obtained by this device are used in the diagnosis and treatment of opiate use or overdose and in monitoring the levels of opiate administration to ensure appropriate therapy.

Special Controls

*Classification.* Class II (special controls). An opiate 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).

Standard/Guidance Document Reference (if applicable) None referenced. # 11. Test Principle Dochek® Multi-Drug Urine Test Dipcard Rx or Dochek® Multi-Drug Urine Test Dipcard is a {11}------------------------------------------------ competitive immunoassay that is used to screen for the presence of various drugs and drug metabolites in urine. It is chromatographic absorbent device in which, drugs within a urine sample, competitively combined to a limited number of drug monoclonal antibody (mouse) conjugate binding sites. When the test is activated, the urine is absorbed into each test strip by capillary action, mixes with the respective drug monoclonal antibody conjugate, and flows across a pre-coated membrane. When drug in the urine sample is below the detection level of the test, respective drug monoclonal antibody conjugate binds to the respective drug-protein conjugate immobilized in the Test Region (T) of the test strip. This produces a colored Test line in the Test Region (T) of the strip, which, regardless of its intensity, indicates a negative test result. When drug level is at or above the detection level of the tree drug in the sample binds to the respective drug monoclonal antibody conjugate, preventing the respective drug monoclonal antibody conjugate from binding to the respective drug-protein conjugate immobilized in the Test Region (T) of the device. This prevents the development of a distinct colored band in the test region, indicating a preliminary positive result. To serve as a procedure control, a colored line will appear at the Control Region (C) of each strip, if the test has been performed properly. # 12. Performance Characteristics # A. Analytical Performance # a. Precision/Reproducibility: Precision studies were carried out for samples with concentrations of +100% cutoff, +50% cutoff, +25% cutoff, cutoff, -25% cutoff, -50% cutoff, -75% cut off and -100% cutoff. Other samples were prepared by spiked target drug in drug-free urine samples. Each drug concentration was confirmed by LC-MS/MS. For each concentration, tests were performed two runs per day for 25 days using three lots of test dipcard. The results obtained are summarized in the following tables: | Drug | Lot<br>Number | +100%<br>cutoff | +75%<br>cutoff | +50%<br>cutoff | +25%<br>cutoff | Cutoff | -25%<br>cutoff | -50%<br>cutoff |
