## Intended Use

At Work Drug Test is a rapid, qualitative immunoassay for the detection of the target drugs/drug metabolites in urine. The cut-off concentrations of this test are as follows: Phencyclidine (PCP); 25 ng/ml, amphetamine; 1000 ng/ml, cocaine; 300 ng/ml and opiates; #9145 25C at 300 ng/ml and 9177 25C at 2000 ng/ml. This assay is intended for use in the workplace assist in the prevention of drug abuse. This kit, as supplied, incorporates a mechanism for confirmation testing by GC/MS, to be performed at a certified laboratory.

## Device Story

At Work Drug Test is a rapid, qualitative, one-step lateral flow immunoassay for urine drug screening. Device detects Phencyclidine (PCP), Amphetamine, THC, Cocaine, and Opiates based on immunochemical sandwich assay principle; specific antibody-target drug complexes form visual color lines. Used in workplace settings by professional users for preliminary screening. Kit includes mechanism for follow-up GC/MS confirmation at certified laboratories. Provides rapid visual results to assist in drug abuse prevention programs.

## Clinical Evidence

Clinical sample correlation study and blind labeled spiked study performed. Compared against Behring EMIT II and GC/MS methodology. Results showed >98% correlation. Clinical studies at two independent laboratories demonstrated >97% overall accuracy for professional users. Consumer study using identical formulation showed >96.4% overall accuracy for lay users.

## Technological Characteristics

Lateral flow immunoassay; visual color sandwich principle; one-step test format. Detects drugs in urine via specific antibody-antigen binding. No electronic components, software, or external energy sources required.

## Predicate Devices

- Phamatech QuickScreen At Home Drug Test
- Phamatech QuickScreen Pro Multi Drug Screening Test

## Reference Devices

- Behring EMIT II

## 510 (k) SUMMARY AS REQUIRED BY SECTION 807.92(C)

At Work Drug Test (Model 9145 25C and 9177 25C) ldentification:

Description: Immunoassay for the qualitative detection Phencyclidine (PCP), Amphetamine, THC, Cocaine and Opiates in urine

Name Of Manufacturer:

Phamatech 9265 Activity Road #112 San Diego, California 92126, USA

Intended Use: At Work Drug Test is a rapid, qualitative immunoassay for the detection of the target drugs/drug metabolites in urine. The cut-off concentrations of this test are as follows: Phencyclidine (PCP); 25 ng/ml, amphetamine; 1000 ng/ml, cocaine; 300 ng/ml and opiates; #9145 25C at 300 ng/ml and 9177 25C at 2000 ng/ml. This assay is intended for use in the workplace assist in the prevention of drug abuse. This kit, as supplied, incorporates a mechanism for confirmation testing by GC/MS, to be performed at a certified laboratory.

The At Work 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 Phamatech QuickScreen At Home Drug Test and the Phamatech QuickScreen Pro Multi Drug Screening Test. 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 Work 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 Work 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 were also performed at two independent laboratories. In them the Phamatech At Work Drug Test™ exhibited excellent overall accuracy (>97%) in the hands of professional users.

A comsumer study using the At Home Drug Test, which utilizes identical formulation and, like the At Work Drug Screening Test, includes GC/MS confirmation testing as a component, was performed. In the hands of lay users the test exhibited excellent overall accuracy (>96.4%).

Conclusion: For the reasons mentioned above, it may be concluded that the Phamatech At Work Drug Test is substantially equivalent to a variety of detection tests currently in commercial distribution and is safe in the hands of the lay user.
