No More Patches: 

 

Across Iowa and the US the Department of Health and Human Services (HHS) is using a drug test called the PharmChek sweat patch by PharmChem (now SCRAM) to take children from their parents. Parents in recovery. Parents with clean urine tests. Parents with negative hair tests. Parents whose counselors, therapists, family support workers, and everyone around them will tell you — they are sober.

 

But none of that matters. Because a patch said otherwise.

 

What we've uncovered will shock you.

 

The FDA says it's a jar. HHS says it's the gold standard.

 

The FDA's own database describes the PharmChek sweat patch as a device that "acts as a specimen container for the non-volatile and liquid components of sweat."

 

That's it. A specimen container. The same FDA classification as a urine cup.

 

- FDA Device Class: 1 — the lowest possible. Same class as tongue depressors and bandages.

- FDA Product Code: FMH — "Container, Specimen, Sterile"

- The FDA never reviewed whether this device accurately detects drug use

- The FDA never set cutoff levels for sweat testing

- The FDA never issued a single guidance document on sweat-based drug testing

 

When HHS tells a judge the patch is "FDA-cleared," they're technically right — in the same way a urine cup is FDA-cleared. The clearance means it holds liquid. It does not mean the results are reliable.

The federal government studied sweat for 21 years — and rejected it.

 

In 2004, SAMHSA — the federal agency that sets drug-testing standards — proposed adding sweat patches to its Mandatory Guidelines. But in that very same proposal, SAMHSA admitted:

 

- "The incorporation of drugs into sweat is poorly understood."

- "Sweat patch contamination issues continue to be a concern."

- "The amount of sweat excreted is variable for each person and between individuals."

 

Four years later, SAMHSA dropped sweat from the final rule. They said "significant issues" required "further examination."

 

That was 2008. It is now 2026. Sweat has never been included in any final federal guideline. Ever.

 

Meanwhile, SAMHSA approved oral fluid testing in 2019 — proving the agency adds new methods when the science supports it. For sweat, the science never did.

 

The tool the federal government rejected as too unreliable for monitoring employees on probation is being used to take children from their parents.

 

The manufacturer sets its own pass/fail levels. Nobody checks them.

 

For urine testing, the federal government sets the cutoff levels through a public rulemaking process. For sweat patches, the manufacturer — PharmChem, Inc. — sets its own cutoffs. No federal agency. No state agency. No international body reviews or validates them.

 

How much lower are PharmChek's self-set cutoffs compared to federal urine standards?

 

Lower cutoffs mean more positives. The company that profits from every test sets its own bar as low as possible. And the lab that processes the patches — Clinical Reference Laboratory (CRL) — holds certifications from SAMHSA, CAP, and others. But not one of those certifications covers sweat testing. When CRL runs a sweat patch, it's operating outside every certification it holds.

 

The manufacturer's own science says the test is only 76% accurate.

 

PharmChem's own peer-reviewed study — published by their own scientists — is titled "QUALITATIVE Detection of Opiates in Sweat." Even the manufacturer calls it qualitative — meaning it can only answer "present or absent," not "how much" or "when."

 

Their own data shows:

 

- Misses 1 in 4 actual drug users (76% sensitivity)

- 14% of positive results are wrong

- Tile cleaner and household detergent cause false positives

- The same sample can produce wildly different results on different runs (39% variability)

 

Despite all of this, HHS and courts treat these results as gospel — overriding negative urine tests, negative hair tests, completed treatment, and the observations of every person who actually knows the parent.

 

"Present" doesn't mean positive. But HHS treats it that way.

 

PharmChek's own Technical Guide says a confirmed positive requires the parent drug AND its metabolite both above specific thresholds. Their Lab Report Guide says: "A result below the cutoff is reported as negative."

 

But HHS social workers routinely treat results reported as "present" — which means below the cutoff — as evidence of drug use. By the manufacturer's own definition, "present" is a negative result. HHS is punishing parents based on results the manufacturer itself says are negative.

 

Independent studies prove the patch picks up drugs from the environment — no ingestion required.

 

- Naval Research Laboratory (1999): Environmental contamination produced results 59 times the positive cutoff — without anyone using drugs

- Department of Justice (2002): Skin cleaning before applying the patch "would never be 100% effective" in removing environmental drugs

- PharmChem's own internal study (concealed until forced out in court): 2 out of 5 patches tested positive from skin contamination alone. The federal prosecutor said he never would have brought the case if he'd known. The case was dismissed.

 

A parent could touch a contaminated surface, ride in someone's car, handle cash, or live in an apartment with prior drug residue — and test positive. Nobody is telling parents this. Nobody is telling judges this.

 

One expert. Every case. Exposed contradictions.

 

Dr. Leo Kadehjian testifies as the State's expert in sweat-patch cases across the country. But his testimony contradicts the manufacturer's own instructions:

 

- He testifies about dose levels — the manufacturer says the patch "cannot determine if multiple small doses or one large dose"

- He testifies about timing of use — the manufacturer says it "cannot determine the exact date or time"

- He uses concentration numbers to characterize use — the manufacturer warns those numbers "can be misleading and should not be used to justify sanctions"

 

He also works as a consultant to the Administrative Office of the U.S. Courts — the agency that contracts for the patches — and trains judges on sweat-patch science, then appears before those same judges as the State's expert. He has never been identified as testifying for a parent. Every time, he testifies for the State.

 

Real families. Real devastation.

 

This is not a policy debate. Children are being taken from sober parents based on a test the federal government rejected, the FDA classified as a jar, and the manufacturer's own scientists called unreliable.

 

Parents who have:

 

- ✅ Completed substance abuse treatment

- ✅ Tested negative on every urine test

- ✅ Tested negative on hair tests

- ✅ Received support from counselors, therapists, and family workers who confirm sobriety

- ❌ Lost their children anyway — because a patch said otherwise

 

Courts refuse to modify testing orders. HHS ignores its own policy that drug tests should be "one component" of a holistic assessment — not the sole determinant. Judges label parents "addicts" and claim they are "under the influence" to justify continued testing, even when every other indicator says otherwise.

 

Undermining a parent's recovery by treating unreliable test results as proof of failure doesn't protect children. It destroys families. And it pushes people back toward the addiction they fought to leave behind.

 

What we're demanding:

 

1. Stop using sweat patches as the primary basis for restricting parenting time until the testing is validated by an independent federal regulatory body

 

2. Acknowledge the FDA's actual classification — this is a specimen container, not a diagnostic test

 

3. Follow SAMHSA's lead — if the federal government rejected sweat testing for its own employees, Iowa should not use it to separate families

 

4. Require independent cutoff validation — not manufacturer-set thresholds designed to maximize positives

 

5. Stop treating "present" as positive — the manufacturer's own materials say it's negative

 

6. Account for prescriptions before labeling a parent a drug user

 

7. Train social workers on the science behind the tests they use to make life-altering recommendations

 

8. Consider what the people who actually know the parent have to say — not just a test result from a device classified as a jar

 

This petition has been filed with the court.

 

This petition and its signatures have been submitted as exhibits in formal court filings in Jones County, Iowa, demonstrating that this problem is systemic, not isolated. Every signature strengthens the record.

 

If you or someone you know has been affected by sweat-patch testing in a child welfare case, your signature matters. Your story matters. And this fight is far from over.
