The device description and performance studies focus on traditional immunoassay technology and statistical analysis of results, with no mention of AI or ML.
No
Explanation: This device is for drug screening and detection, not for treating a disease or condition.
Yes
Explanation: The device is intended for home drug screening to detect the presence of drugs of abuse in urine, which is a form of diagnostic testing.
No
The device description clearly states it is an immunoassay kit that uses visual color sandwich one step immunoassay technology, which is a hardware-based test.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "A home drug screening, and if needed, confirmation service." This involves testing a biological sample (urine) to detect the presence of substances (drugs of abuse).
- Device Description: It explicitly states it's an "Immunoassay for the qualitative detection of THC in urine." Immunoassays are a common type of in vitro diagnostic test. It also describes the test as a "rapid, qualitative immunoassay for the detection of the target drugs/drug metabolites in urine."
- Anatomical Site: The sample being tested is "Urine," which is a biological specimen.
- Mechanism: The description of the technology ("visual color sandwich one step immunoassay technology") confirms it's a test performed outside of the body on a biological sample.
All of these points align with the definition of an In Vitro Diagnostic device, which is a medical device intended for use in vitro for the examination of specimens derived from the human body solely or principally for the purpose of providing information concerning a physiological or pathological state, or concerning a congenital abnormality, or to monitor therapeutic measures.

Intended Use / Indications for Use
The At Home Drug Test is a rapid, qualitative immunoassay for the detection of the target drugs/drug metabolites in urine. The cut-off concentration for this test is as follows: THC (or marijuana): 50 ng/ml. This assay is intended for use in the home to assist in the prevention of drug abuse. This kit is designed to incorporate a mechanism for anonymous confirmation testing to be performed at a certified laboratory.

The product performance characteristics of the At Home Drug Test were evaluated in a clinical sample correlation study and a blind labeled spiked study. The results of these studies demonstrate the Phamatech At Home Drug Test to be substantially equivalent to the reported performance characteristics of other commercially available tests for the qualitative detection of the stated target drugs in urine. Correlations studies, using clinical specimens, produced a >98% correlation when compared to the Behring EMIT II (Cupertino, CA 95014) and GC/MS methodology. Clinical studies, performed at two independent laboratories, were also performed. In them the Phamatech QuickScreen™ exhibited excellent overall accuracy (>97%) in the hands of professional users. A comsumer study was also performed. The At Home Drug Test exhibited excellent overall accuracy (4557/4715 correct or 96.65%) in the hands of lay users. Consumer interpretation of the THC test in this study showed accuracy to be 915/943 or 97.0%.

§ 862.3870 Cannabinoid test system.
(a)
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 includedelta -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.(b)
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).

510 (k) SUMMARY AS REQUIRED BY SECTION 807.92(C)
At Home Drug Test (Model 9078) Identification:
Description: Immunoassay for the qualitative detection of THC in urine
Name Of Manufacturer:
Phamatech 9265 Activity Road #112 San Diego, California 92126, USA
Intended Use: The At Home Drug Test is a rapid, qualitative immunoassay for the detection of the target drugs/drug metabolites in urine. The cut-off concentration for this test is as follows: THC (or marijuana): 50 ng/ml. This assay is intended for use in the home to assist in the prevention of drug abuse. This kit is designed to incorporate a mechanism for anonymous confirmation testing to be performed at a certified laboratory.
The At Home Drug Test, like many commercially available drug screening test Technology: kits, qualitatively measures the presence of target drugs or their metabolites by visual color sandwich one step immunoassay technology. Examples of such predicate devices include the QuickScreen At Home Drug Test and the Applied Biotech SureStep Test (San Diego, CA 92121). All of the above devices rely on the basic immunochemical sandwich assay principle of recognition and formation of specific antibody / target drug / antibody / complexes.
Performance: The product performance characteristics of the At Home Drug Test were evaluated in a clinical sample correlation study and a blind labeled spiked study. The results of these studies demonstrate the Phamatech At Home Drug Test to be substantially equivalent to the reported performance characteristics of other commercially available tests for the qualitative detection of the stated target drugs in urine. Correlations studies, using clinical specimens, produced a >98% correlation when compared to the Behring EMIT II (Cupertino, CA 95014) and GC/MS methodology. Clinical studies, performed at two independent laboratories, were also performed. In them the Phamatech QuickScreen™ exhibited excellent overall accuracy (>97%) in the hands of professional users. A comsumer study was also performed. The At Home Drug Test exhibited excellent overall accuracy (4557/4715 correct or 96.65%) in the hands of lay users. Consumer interpretation of the THC test in this study showed accuracy to be 915/943 or 97.0%.
Conclusion: For the reasons mentioned above, it may be concluded that the Phamatech At Home Drug Test Model 9078 is substantially equivalent to a variety of detection tests currently in commercial distribution and is safe in the hands of the lay user.
