Getting tested in Chicago
The Michigan Avenue office is steps from the Loop, Erie Street serves Streeterville and the hospitals, and the 63rd Street site covers the South Side. Suburban or out-of-state participants pick their own approved centers, and the laboratory links every sealed sample into one case.
Questions people in Chicago ask us
Every one of these gets asked on the phone daily. No judgment, just answers.
Do we all have to go to the same test center?
No, and in most cases people don't. Each person being tested picks their own center when you order, walks in on their own schedule, and the laboratory links the sealed samples into one case. Mother in one city, child in another is routine, and the result carries the same weight as if everyone had been collected side by side.
What does everyone bring to their collection?
Valid identification: a driver's license, state ID, insurance card, or anything showing their name. The collector verifies who each person is, witnesses the cheek swab, and seals the sample into a chain-of-custody package on the spot. That verification is exactly what makes the result court-admissible. A child under 18 comes with a consenting guardian instead of their own ID.
Will the result hold up in court?
Yes. Courts, child support agencies, and USCIS accept witnessed chain-of-custody DNA results, and that standard is the entire difference between this test and a home kit. The science is the same; the difference is that a trained collector verified who gave each sample and documented every step. You can order it yourself today and the result is admissible if you ever need it to be.
How fast do results come back?
Usually 3 to 5 business days after the last person is collected. The clock starts when everyone has walked in, so the fastest cases are the ones where each participant goes early. Results post to your secure online account, and you alone decide who sees them.
Can a child be tested, and who has to agree to it?
Any age, newborn up. The cheek swab is painless and takes seconds. A minor is collected with a consenting guardian present who signs on their behalf; that is the operational rule at every center. If custody of the child is itself the dispute, call us at (866) 873-0879 first and a Care Advisor will walk through how collection works in your situation.
Will a self-ordered DNA test hold up in Cook County court?
Yes, when collection is witnessed with identification under sealed chain of custody, which is what this is. Illinois courts read the custody documentation, not the receipt. The same standard covers parentage and support filings statewide.
