No
The device description explicitly states it uses "visual color sandwich one step immunoassay technology" and the performance studies focus on correlation with established methods and user interpretation of visual results. There is no mention of AI, ML, image processing, or any data-driven algorithms for interpretation.
No
This device is a diagnostic tool used for screening, not a therapeutic device designed to treat or alleviate a medical condition.
Yes
The device is described as a "home drug screening" kit that provides a "preliminary result for the detection/presence of the following drugs of abuse in urine." This indicates its purpose is to identify or diagnose the presence of drugs.
No
The device description clearly states it is a "rapid, qualitative immunoassay" and describes a physical test kit that uses "visual color sandwich one step immunoassay technology," indicating it is a hardware-based test.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide a preliminary result for the detection/presence of drugs of abuse in urine. This involves testing a sample taken from the human body (urine) in vitro (outside the body) to gain information about a physiological state (presence of drugs).
- Device Description: It is described as a "rapid, qualitative immunoassay for the detection of the target drugs/drug metabolites in urine." Immunoassays performed on biological samples like urine are a common type of IVD.
- Performance Studies: The performance studies involve testing clinical samples and spiked samples to evaluate the device's accuracy in detecting the target substance in urine. This is typical for IVD devices.
- Predicate Devices: The predicate devices listed are also drug screening tests, which are generally classified as IVDs.
The fact that it's intended for home use by a lay user and provides a preliminary result does not change its classification as an IVD. It is still a test performed in vitro on a human sample to provide diagnostic information.

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: Cocaine (benzoylecgonine): 300 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.
A home drug screening, and if needed, confirmation service. This kit provides a preliminary result for the detection/presence of the following drugs of abuse in urine: Cocaine (benzoylecgonine).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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. Correlation 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 Druq Test exhibited excellent overall accuracy (4557/4715 correct or 96.65%) in the hands of lay users. Consumer interpretation of the Cocaine test in this study showed accuracy to be 917/943 or 97.24%.

§ 862.3250 Cocaine and cocaine metabolite test system.
(a)
Identification. A cocaine and cocaine metabolite test system is a device intended to measure cocaine and a cocaine metabolite (benzoylecgonine) in serum, plasma, and urine. Measurements obtained by this device are used in the diagnosis and treatment of cocaine use or overdose.(b)
Classification. Class II (special controls). A cocaine and cocaine metabolite 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 9073) ldentification:
Description: Immunoassay for the qualitative detection of Cocaine (benzoylecgonine) 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: Cocaine (benzoylecgonine): 300 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. Correlation 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 Druq Test exhibited excellent overall accuracy (4557/4715 correct or 96.65%) in the hands of lay users. Consumer interpretation of the Cocaine test in this study showed accuracy to be 917/943 or 97.24%.
For the reasons mentioned above, it may be concluded that the Conclusion: Phamatech At Home Drug Test Model 9073 is substantially equivalent to a variety of detection tests currently in commercial distribution and is safe in the hands of the lay user.
