Top Five Frequently Asked Questions ( Sweat Patch)
1. Is the sweat patch new technology?
No. Drugs have been known and detected in sweat since the early
1970's. The principle challenge with respect to sweat testing has been
the collection of sweat. The PharmChek® Sweat Patch is a
non-occlusive device that facilitates the collection of sweat.
2. Are the testing procedures used for the analysis of sweat considered new technology?
No. The testing procedures used for the analysis of sweat are the
same well-established procedures used for the analysis of urine
specimen. Specimens are screened using an enzyme immunoassay
technique. Positive specimens are confirmed using liquid
chromatography/mass spectrometry/mass spectrometry (LC/MS/MS).
Both procedures utilize certified calibrator and quality control
3. Have these procedures been submitted to and cleared by the Food and Drug Administration (FDA)?
Yes. The FDA, through its procedures have cleared the PharmChek®
Sweat Patch as both a specimen collection device and as a
scientifically valid procedure for the detection of drugs in sweat.
Why is this different from hair testing?
Hair testing is capable of detection chronic drug use but has difficulty
detecting occasional or recreational drug use.
5. What does the sweat patch detect, and how does this differ from urine testing?
Unlike urine testing that detects drug metabolites, sweat testing
detects the parent or non-metabolized form of the drug. This is
particularly important when testing for abused drugs such as heroin
that can only be detected in urine for a short time period following
use. Heroin is rapidly metabolized to 6-acetyl morphine then to
morphine. Consumption of poppy seeds can also produce a positive
morphine result, as can the use of a codeine based medication.
Because the sweat patch can detect heroin, it can determine if a heroin
user is attempting to mask the heroin use with either codeine or poppy seed use.
