Frequently Asked Questions

24/7 Drug of Abuse Monitoring FAQs

How does the patch work?

Worn on the candidates skin for a pre-set wear period. The PharmChek® Sweat Patch captures insensible perspiration, the uncontrolled loss of sweat from the skin, in the absorbent pad. Approximately 300-700 ml of insensible sweat is excreted each day, and about 2ml is absorbed in the patch each week.

The polyurethane film is a semi-permeable membrane that allows small molecules, such as oxygen, carbon dioxide, and water vapor to pass through the patch— leaving the skin underneath healthy and sterile. Substances of large molecular weight are trapped in the absorbent pad of the patch and submitted to the laboratory for analysis.

We would like to answer any questions you may have.
