Most people don't realize there are two different tests until they start looking — and they serve very different purposes.
A private at-home test is right if you're testing for your own understanding only — a self-collected cheek swab, mailed in, private results. If the result needs to hold up in a Cook County courtroom or a child support case, the legal version is required, using a supervised, documented collection that can be relied on as evidence.

In Illinois, at-home DNA test results are not accepted as legal proof of paternity; courts and child support agencies require a chain-of-custody genetic test performed at an accredited facility, with witnessed collection and identity verification, before parentage can be legally established.
