PharmChek® Sweat Patch: Key Features and Benefits
Collection Method:
Captures insensible perspiration (uncontrolled sweat loss) in an absorbent pad.1
Collects approximately 2ml of sweat per week.
Daily insensible sweat excretion ranges from 300-700 ml.
Semi-Permeable Membrane:
Utilizes a polyurethane film that acts as a semi-permeable membrane.
Allows small molecules (oxygen, carbon dioxide, water vapor) to pass through, maintaining healthy and sterile skin underneath.
Traps larger molecules.
Drug Detection:
Substances of large molecular weight (drugs and their metabolites) are trapped in the absorbent pad.
The pad is submitted to a laboratory for analysis.
Advantages:
FDA-cleared for drugs of abuse detection.
Provides a successful and economical alternative to urinalysis.
Provides distinct advantages over urinalysis.
Key points:
The patch collects sweat passively, over a period of time. This creates a longer window of detection than a urine test.
Because it is worn on the skin, it is far more difficult to adulterate than a urine sample.
In essence, the PharmChek® Sweat Patch offers a non-invasive, continuous monitoring approach for drug detection, providing a valuable alternative to traditional urine testing.
