Intended Use

The First Check Home Drug Test (THC) is an educational screening test for the rapid detection of THC (and its metabolites) in human urine at a cut off for the rapid dececeion of the (antended for consumer use as the first step in a two step process to provide consumers, including but not limited to concerned a two seep process to provious concerning the presence of THC (and its parents, with information obliozing is beneficial to consumer metabolices) in a arine baspeable laws and/or societal expectations. Information regarding second step confirmatory testing is provided.

Device Story

First Check Home Drug Test (THC) is a rapid, one-step chromatographic immunoassay for qualitative detection of THC and metabolites in human urine; cut-off concentration 50ng/mL. Device utilizes antibody/target drug/antibody complex formation principle. Intended for lay-user/consumer self-testing; no special training or licensure required. User applies urine sample to test card well; visual color change indicates presence or absence of target. Results serve as preliminary screening; information provided for mandatory second-step confirmatory testing. Benefits include providing consumers/parents with information regarding drug presence for personal or societal awareness.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological characteristics and performance equivalence to the predicate device. The device relies on established one-step chromatographic immunoassay principles.

Technological Characteristics

One-step rapid chromatographic immunoassay. Principle: recognition and formation of specific antibody/target drug/antibody complexes. Cut-off concentration: 50ng/mL. Form factor: test card. No electronic components or software.

Indications for Use

Indicated for consumer use as a preliminary, rapid screening test for the detection of THC and its metabolites in human urine. Intended as the first step in a two-step process to provide information regarding the presence or absence of THC in a urine sample.

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).

- Contact Person: H. Thad Morris D.
- Date of Preparation of this Summary: September 29, 1999 II.
- III. Trade Name: First Check® Home Drug Test (THC)
- Common Name: At home drugs of abuse rapid screening test for THC in IV. urine
- Classification Name: Immunoassay for the qualitative detection of THC in V. urine
- The Marketed Products to Which Equivalence is Claimed: The First VI. Check® Home Drug Test (THC) that is the subject of this submission is identical to the Applied Biotech SureStep™ Drug Screen THC Test in terms of intended use, product design, performance characteristics, materials of construction, and manufacturing process. It is also substantially equivalent to the Phamatech QuickScreen™ At Home Drug Test and other commercially available drug screening tests which qualitatively measure the presence of target drugs or metabolites by visual color one step immunoassay technology.
- Statement of Intended Use Compared to Other Products: The intended use VII. of the First Check® Home Drug Test (THC) is substantially equivalent to the listed products; it is a preliminary, rapid screening test for the detection of THC and its metabolites in urine. This product is intended to be the first step in a two step process to provide consumers, including concerned parents. with information regarding the presence or absence of THC (and its metabolites) in a urine sample. Information regarding the second step, confirmatory testing, is provided.

- Discussion of Technological Characteristics: The First Check® Home VIII. Drug Test (THC), like many commercially available drug screening tests, qualitatively measures the presence or absence of THC and its metabolites in urine using a one step rapid chromatographic immunoassay which operates under the principle of recognition and formation of specific antibody/target drug/antibody complexes. The cut-off concentration for THC is 50ng/mL.
- IX. Safety and Effectiveness: Because the First Check® Home Drug Test (THC) is identical to the Applied Biotech SureStep™ Drug Screen THC test that is legally marketed under K960744, and because no special skills, training, education, or licensure are required to transfer a dropper level of urine sample into the test card well, there is no issue regarding the safety or effectiveness of the product to perform its intended function, i.e., to screen urine for the presence or absence of THC and its metabolites. Because the labeling of the First Check® Home Drug Test (THC) is substantially equivalent to a variety of rapid screening tests currently in commercial distribution, including the Phamatech QuickScreen™ At Home Drug Test, and there have been no reports of consumer inability to follow instructions or interpret results during the twenty-four months the product has been purchased by the general public and used in quantities exceeding 87,000 tests, it is concluded that the product can be used effectively by the lay user.
