This marijuana THC urine test detects THC at the absolute lowest level of detection available for at-home testing kits. With UTest, you get results from below the industry testing standard of 50 ng/ml, at an ultra sensitive15 ng/ml level.
  • EXCLUSIVE SINGLE PANEL MARIJUANA DRUG TEST - The accurate single test strip detects THC in any form including CBD and hemp products at the 15 ng/mL level, and with 99% accuracy. This allows you to detect even the faintest trace of THC in your system so that you know when it is safe to take official tests for work, school, sports, and more.
  • RESULTS IN 5 MINUTES - These THC test strips are the first home cannabis detection test that measures drug levels as low as 15 ng/mL. That is comparable to laboratory GCMS testing so UTest users get the assurance they need to pass a standardized urinalysis lab test. It produces the results quickly, within 5 minutes of collecting your urine sample.
  • EASY TO USE URINE TEST - This quick testing kit for home is a one step, easy to use, self testing device. Collect a urine sample, then dip the absorbent end of the test into your sample until the “C” line appears. Next, replace cap back onto the absorbent end and lay your test on a flat surface. Read your results at 5 minutes.
  • ALL-IN-ONE TESTING & SUPPORT SERVICE - We are not just a product, we are a service. Each kit is designed for at-home use and includes UTest test(s), an informational pamphlet, a results tracking sheet, instructions, test interpretations, and complimentary customer service contact.

okay so im just gonna start off by saying im an infrequent user meaning I smoked usually 4-5 a month. Probably 2-3 hits max. I usually smoke thc carts, joints, blunts, once from a bong (idk if that matters) anyways. I had smoked Saturday, probably 2 hits max from my wax pen, (before this I had smoked the previous Thursday so 2 days before 2-3 hits max) the following Monday I was advised to complete a drug test within 72 hours. I completed it the last day to get the best chance of coming out negative. Mind you my employer is checking for 12 panel, urine test. I bought a 50mg THC test from CVS on Monday to see where I was at, I tested negative. I bought another thc test from the dollar store and tested negative. Still was hesitant did more research. Found out different labs do different cut off levels. You can search on google for cut off levels if you know the lab, mine was quest. For quest they do urine thc cut off levels at 50mg and confirmatory test at 15mg. This confirmatory test is ONLY used when the 50mg comes out positive meaning you failed so they’re testing you at 15mg to confirm. Now, I know I tested negative at 50mg but I wanted to be a extra sure. I ordered these 15mg test and took them on Wednesday. I was negative, the line showed up but was very faint. I tested again Thursday (the day of my test) and I was very faint, negative. After my drug test, I smoked. I bought a thc test from the dollar tree and boom came out positive, only reason I mention this is don’t waste your money on 20-30 dollars worth of test at cvs, just buy them at the dollar store. Anyways here I am 3 days later and HR is continuing my onboarding process so I’m guessing I passed my urine test (I’ll update if I didn’t). This was my experience but please do you research. Also if you’re going to try detox methods please do your research as *most* don’t work. You have to let nature take its course unfortunately. *I did not participate in any detox, excessive exercises, excessive water drinking, etc* just know how to play the game.

5.0 out of 5 stars Excellent product review answers ALL QUESTIONS
Reviewed in the United States on February 17, 2020
Please read! Excellent product, 100% recommend. People must be doing these wrong and not reading the directions because it is so simple I don’t know how you could screw it up. It is the most sensitive test on the market! 20/5ng. If you are getting a drug screen and it will be put through a gas spectrometer there’s no way of cheating it, if you’re clean on this you are clean! Things that you need to know and exactly how to do it:

Do not buy the products that state it will make you clean, they are a lie. The technology can pick up on the chemicals that are in those so-called detox products, you will fail.

Do not drink an exorbitant amount of water, You will fail! The machine will see that it is diluted.

Do not use other peoples urine or fake urine because it will test for male or female, plus also every single medication that you are on and if somethings off, you fail.

Having said that.... I’ve never been in that situation nor will I ever be I am a medical marijuana card holder. Some doctors prefer that you stay under an amount of THC in your urine, The gas spectrometer test shows exactly how much you have in your system. You can purchase ones that have a five panel that go from 15 all the way up to 300. Those are nice to see where you stand. Remember the higher you are the longer it takes to get out of the system, and I mean the number. If you Vape, it will stay in your system much longer as do edibles. But it seems to be eliminated from the body much more quickly. However it can still build up and take a long time for it to get out of your body. So if you are going to need this test for a job even though you have a medical marijuana card, this is the test you need to make sure that you will pass!

First thing you need to do is, on the front of the package shows the information peel off the front sticker and it will show you perfect directions! Find yourself a cup for your sample, make sure that you clean it out with alcohol wipe it out and let it dry. Attain a small sample set it aside. Tear open your pouch, TAKE OFF THE BOTTOM CAP OF THE TEST!!!!!! Place the dipstick(only down to the first green line no farther!) into your sample and keep it there, straight up and down, for approximately 5 to 20 seconds depending on how long it takes to reach the C line. Once the dye reaches the C line gently take it out of the sample, do not shake! Put the cap back on and end set it down flat then walk away for 1 to 2 minutes. Come back and read your test. If you have only a line at the C then you have failed. If you have two lines one at the T and the one at the C you have passed! The two lines do not have to be the same color one is more likely than not going to be lighter than the other and that’s usually the T line. You should see it with your naked eye or readers if you need them when you read a book, if you need to get a magnifying glass to see if there is a line there… You have failed! If you need to take a picture with your phone and blow it up 100 times, I would bet pretty much that you have failed. You will see the line clearly the faintly when you are clean!

The more you smoke the longer it will take for it to get out of your system. Even if you smoke or have an edible or whatever your intake is if it is more than twice a week it will probably take up to two months for it to be completely clean out of your system. If you know you’re going to have a test, get a baseline test a five panel screen and see where you are and start making plans. There is no magic cure except for letting nature take it’s course! I hope that this has helped a lot of people and answered a lot of questions.

EXTREMELY IMPORTANT!! If you smoke a lot in your home, or you use lotions with THC in it you need to make sure that you wash your sheets and clothing etc. because it will just get re-absorbed into your skin therefore you will then test positive. Also if you go to clubs constantly and you know even at a friends house if they are smoking chilling and you’re not, you can still get a positive test because you Are absolutely breathing in THC. Everyone needs to start waking up and thinking about reality and the consequences of your own actions, if you want a job, stay out of jail if you’re on probation, or keep your pain medications prescribed to you, then I highly suggest you heed my warning‘s because these doctors aren’t playing around anymore and they absolutely will not give you the benefit of the doubt whether or not medical marijuana is legal and you are prescribed it or not every doctor can react differently so you better know whom you are dealing with. Good luck and take care all

Definitely read the instructions on the back before using so you don’t mess up!!

My husband and I both used this test this morning (mine is on the right and my husband’s is on the left in the pictures). It was very simple and fast. My husband had a fainter line than me which worried us at first, but then I read the pamphlet where it explains that even a faint red line is clean. We both went in for our drug tests today with peace of mind and both of us passed 👍 Thank you!

Reviewed in the United States on February 11, 2024
That line was SO faint I was sure I would fail, but I had no choice. I hadn’t smoked or consumed any THC in about three weeks. I’m 5’5 180lbs, so I figured I was cutting it close. I work from home, and I only walk 2 miles a day on the weekends for exercise. I had to go to a clinic in town who does the drug testing for all different companies—you know where they put blue dye in the toilet so they can tell if you flush. And they sent my drug test out to an outside lab for a 9 Panel test. And I passed! That test scared the crap out of me. That line was so faint, I felt like a teenager trying to deny a positive pregnancy test. I was holding that thing up to the light to make sure that the line was actually there. But it was, and I passed!! 10 out of 10 babyyy!!
