Proven Advantages of the PharmChek® Sweat Patch


Continuous Collection for a Week or More

Conventional urinalysis provides only a few days of detection. The Sweat Patch offers up to 7 to 10 days of continuous sample collection (and up to 14 days when paired with the optional PharmChek® Overlay). With the PharmChek® Sweat Patch, you get a more comprehensive picture of drug use patterns with your clients to support recovery and accountability.


Wide-Range Detection Panels

Confidently detect the most common drugs of abuse, with additional panels available for common opioids. Each PharmChek® patch is screened by our partner SAMHSA-Certified lab, via immunoassay, with presumptive positives confirmed by LC/MS/MS.

Quick Application & Removal

Not only does the Sweat Patch require fewer appointments, leading to greater drug testing compliance, but application and removal take less than 10 minutes.

Noninvasive & Gender Indifferent

Testing with PharmChek® maintains privacy and does not require invasive sample collection methods. With PharmChek®, same-gender observation is also not required. Male officers can apply PharmChek® to female clients and vice versa. With the 24-7 continuous collection of both parent drugs and metabolites, Sweat Patch results are equally accurate, regardless of gender.



The PharmChek® Sweat Patch is tamper-evident. A trained observer can quickly and easily determine whether a patch has been removed or compromised, providing more reliable test results. This level of visibility encourages more open discussions about recovery progress and lapses.


Perfect for Rewards and Sanctions

With its long window of detection, PharmChek® can provide recovering users with consistent accountability, helping them prove sobriety and be rewarded for it, serving as an external motivator to cease drug use.
