Why does the Trained Observer use single-use disposable tweezers and plastic disposable gloves when removing the cellulose - absorbent pad from the PharmChek® patch?
So the Donor won’t catch any germs from the Observer
So the Observer won’t catch any germs from the Donor
So the Donor can’t say that drug found on the patch got there because the Observer touched the cellulose - absorbent pad with his hands
The PharmChek® patch can be purchased and used by:
Anyone who wants to buy it
Only by those who have passed the patch certification exam and operate within a professional environment
Both A & B

It is impossible to have an allergic reaction to the patch

Test the sample
Return it to you
Will not be able to test the sample
A specimen will be “No Tested” if:
The cellulose - absorbent pad inside the specimen bag looks dirty
If the polyurethane film is attached to the cellulose pad
If you send in the second copy of the chain-of –custody instead of the first copy
The PharmChek® patch is usually able to detect more people who take cocaine and amphetamines/methamphetamines than urine testing because:
It is only used on cocaine or amphetamines/methamphetamines addicts
The PharmChek® patch has a longer “Window of Detection”
Cocaine and amphetamine/methamphetamine only show up in sweat, not urine
Will “flushing” or drinking a lot of water after taking drugs keep you from having a positive drug result with a PharmChek® patch?
If a person has a tattoo on the area where you want to put the PharmChek® patch:

Slap the patch on and hope it sticks
Thoroughly clean the area with a minimum of two alcohol pads, aggressively rubbing to remove the dirt, oil & dead skin cells
Let the donor clean his own arm
What are the reasons the patch would “just fall off”?
The donor took a shower.
The donor went swimming.
The donor got tired of wearing the patch and took it off.
How do we know that a positive Cocaine or Amphetamine/Methamphetamine result is not caused by passive contamination from the environment?
The laboratory will not issue a positive cocaine or amphetamine/methamphetamine result unless both the parent drug and the drug metabolite are at, or above, the 'limit of detection'
The molecular structure of the polyurethane film will only permit molecules the size of water vapor to pass in and out. Drug molecules are much larger
The donor was never in the company of a drug user.
Is it possible to have a positive sweat patch result and a negative urine result?
Has the PharmChek® Sweat Patch been accepted by the Courts?
Yes, there have been many court cases, both at the Federal and local level in which the results of the sweat Patch have been challenged and successfully defended.
No, the Patch has never been challenged in a court of law.
What methodology is used to confirm a presumptive positive Sweat Patch?
LC/MS/MS (liquid chromatography/tandem mass spectrometry)
GC/MS (gas chromatography/mass spectrometry)
A presumptive positive patch is not confirmed.
If a positive patch result is reported:
It is not possible to know when the drug use took place.
The drug use may have taken place six months before the patch was applied.
The drug use took place between 24 - 48 hours before the patch was applied or during the wear period up to 24 hours before removal, or both -- however, it is not possible to determine precisely when the drug use occurred.
