Forensic testing: what it means and why it matters

"Forensic" means the test is done so the result can be used in court. That takes four things:

• Your ID is checked before the test.
• Your sample is sealed in front of you.
• Every handoff is signed on a chain-of-custody form, from the collection site to the lab.
• The result goes straight to the people who need it, not through you.

Why it matters

If any step is missing, the other side can question the result, and the court can refuse to accept it.

A doctor's test is not a forensic test

Tests ordered by your doctor or bought online for health reasons are clinical tests. Their reports usually say so, with wording like "for medical use only." Opposing counsel will point to that line, and the court can reject the result — even if it's clean.

The bottom line

If a court or an attorney will see your result, start with a forensic test. It can't be fixed afterward.
