What Does a Single-Panel THC Test Screen For?
One substance—every way it enters your body. This screen checks your urine for THC-COOH, the metabolite your body produces after processing THC. In plain English: It doesn't matter how the THC got there. Smoked flower, joints, high-potency vape cartridges, dabs, waxes, gummies, infused drinks, and tinctures all break down into the same metabolites.
Delta-8, delta-9, delta-10, and THC-O count too. Hemp-derived products break down into the same THC metabolites this screen detects. Legal to buy in Arizona does not mean invisible on a drug screen—if you use delta-8 gummies or vapes regularly, expect them to show up on your result.
CBD is the gray zone. Pure CBD isolate contains no THC and shouldn't register. But many over-the-counter full-spectrum products carry trace amounts of THC that build up with daily use. If your routine includes full-spectrum oils or convenience-store gummies, testing yourself first is the smart move.
Stop guessing—just walk in today and know exactly where you stand.

Urine, Hair, or Saliva — Which THC Test Do You Need?
The right test depends on how far back you need to look.
We offer all three methods at our Mesa walk-in lab, and matching the method to your situation makes the difference between an answer and the right answer.
Urine testing is our most requested rapid screen — the standard for job screening and personal peace of mind, with negative results in about 15 minutes.
Hair follicle testing is the long-view option. When you need to demonstrate a sustained drug-free record for child custody or a strict employer, hair provides a 90-day lookback that detox shampoos and quick fixes can't rewrite.
Explore our hair follicle drug testing options for details.
Saliva testing captures very recent use only, which is why employers reach for it after workplace incidents. It's available as a walk-in service
We'll match you to the right method in one conversation.
Who Can See Your THC Test Results?
One of the biggest concerns for walk-in clients is data privacy.
Your results are yours. When you pay out of pocket for a personal test, nothing goes to an insurance network, a state database, or your medical record.
We don't send results to an employer, a doctor, or anyone else unless you sign a written release telling us to.
The visit is as private as the data. From the moment you walk in, testing happens in a completely private, professional lab setting, and your results are delivered to your secure online portal — not left on a voicemail, not mailed to your house.
If you're testing yourself before someone else tests you, that answer stays yours alone.
THC DRUG TEST FAQ
How long does a THC test take in Mesa? Your visit takes about 15 minutes from the moment you sit down. A negative rapid screen is ready in minutes; confirmation testing, if needed, takes 24–48 hours.
Will delta-8 make me fail a THC drug test? Very likely, yes. Delta-8, delta-9, delta-10, and THC-O break down into the same THC metabolites this screen detects, so regular use commonly triggers a positive result — even though the products are legal to purchase in Arizona.
Can I use this test to check my own levels after quitting? Yes — this is one of the most common reasons people walk in. Many retest weekly to watch their result move from positive to negative, so you have real proof of your progress instead of guessing.
