Questions people in Katy ask us
Every one of these gets asked on the phone daily. No judgment, just answers.
What do I bring to my drug test?
Two things: your test pass (on your phone is fine, printed works too) and a valid government photo ID - driver's license, state ID, or passport. Drug screens check both. Go within your pass's time window, and inside the center's drug-screening hours.
How fast do I get my result?
Lab drug panels post to your secure online account, usually in 1-2 business days. Every non-negative screen is confirmed by the laboratory before anything is reported - the report you receive is the finished, confirmed answer.
My employer needs the result - how do they get it?
From you. The report posts to your private account; you download the PDF and share it with the employer yourself. You stay in the chain and see exactly what they see.
Will this work for court, custody, or probation?
That's what lab panels are for - a full laboratory screen with confirmation testing, the standard courts expect. Match the panel count your paperwork names (9 or 10; every substance is listed on the product page), and if the order's wording is unclear, call us and a Care Advisor will match it with you.
What if I can't get there within my pass's window?
Call us at (866) 873-0879 and we'll issue a fresh one. Life happens - the test still gets done.
My case is filed in Fort Bend County but I live in Katy. Does the location matter?
No, what the court cares about is the chain-of-custody collection and the confirmed lab panel, not which approved site drew the sample. Test at Fry Road, match the panel your paperwork names, and the report you download carries the same weight.
