For custody, DUI, criminal, and parentage cases, we help you pick the test that actually answers the question — and tell you what the result will and won't prove in court. Donors test at an accredited site near them, anywhere in the US. Chain-of-custody that holds up is assumed, not the pitch. Serving attorneys since 2010.
Identity verified, collection documented, custody unbroken — built so the result stands up when opposing counsel pushes on it. Testing is performed by accredited partner laboratories.
Michael Gammel has testified on chain of custody in Chicago-area family court, speaks at ISBA conferences, and serves on an AFCC of Illinois panel. The collector can explain the result on the stand.
Same-week collection in most cases, and a human on the phone who knows your matter — not a ticket queue.
We test both sides the same way and document everything the same way. Neutrality is the point — we answer to the court, not to either party.
Donors complete an oral fluid collection at home or office while a TrueTest staff member observes live via video. Immediate screening result. No collection site visit. No collection fee, and no lab fee on a negative.
Schedule a video test or call 847-258-3966Note: Results are screening results, not lab-confirmed. Best for parenting plans and consent orders requiring ongoing monitoring. Screening tests give a yes/no reading, not a number, and no specimen is retained for re-testing. Oral fluid also covers a shorter recent window than urine. A positive triggers a full chain-of-custody lab collection.
Electronic orders are placed immediately and we select the most convenient certified collection site near the donor — whether near home, work, or anywhere across the country.
For clients who require discretion, mobile drug testing is available in the comfort of their home. Ideal for sensitive custody or legal situations requiring privacy.
Forensic vs. diagnostic testing, the laboratory report vs. the MRO report, and how to match hair, urine, PEth, and sweat-patch testing to the question your case is actually asking.
Read the attorney guide →A short, neutral explainer to hand a client: why a court-ordered test is different from a clinic visit, why chain of custody matters, and what to do first — so their result actually counts.
Share the client guide →What the 90-day window really covers, what a positive does and doesn't establish, why environmental exposure cuts differently in family court, and how the panel named in an order decides the cost.
Read the hair testing guide →The same panels as hair over a longer window — fingernails to about six months, toenails up to twelve. When nails are the right call, where they're weaker, and what an order has to say before hair runs out.
Read the nail testing guide →A hair test run on the child rather than the parent, built to separate what was merely in the home from what the child's body actually processed — and what a court can and can't take from it.
How Child Guard works →The provisions where testing orders most often come up short — naming the test rather than the substance, requiring forensic collection, and specifying who receives which report.
What an order should specify →What a PEth number can and can't establish about drinking, why the same result gets read two different ways in court, and what to check before relying on one.
Read the PEth guide →What a cutoff is and why one exists, how a screening result differs from a confirmation, which number on the report the determination actually rests on, and what a negative does and does not show. With annotated hair, PEth, and urine reports.
