(function() { P.when('cr-A', 'ready').execute(function(A) { if(typeof A.toggleExpanderAriaLabel === 'function') { A.toggleExpanderAriaLabel('review_text_read_more', 'Read more of this review', 'Read less of this review'); } }); })(); .review-text-read-more-expander:focus-visible { outline: 2px solid #2162a1; outline-offset: 2px; border-radius: 5px; } Definitely accurate. You should test negative multiple days in a row to be sure you're negative. Will buy again. Wish it came with more in a pack.

These are AMAZING! I bought this brand and one other and this test is much MORE sensitive. I tested negative on the other and still positive on this test thanks to its higher sensitivity! Must buy if you need to know! Great price!

I can’t speak to if the 15 ng/ml reading is accurate - I have no idea if they actually truly test that low, but I CAN say that they detect whether or not THC is present in the urine sample used.In the photo, left test is of non-smoker (pass) and right test is daily smoker (fail).If you read thru the other comments, you’ll see a lot of complaints. Many which sound valid but plenty of commenters are getting their facts wrong.1. It takes around 3 days for THC to show in your urine. If you tested someone TODAY who smoked once the night before (I.e. they are not a daily smoker), they will test negative for a couple of days until the body metabolizes the THC.2. This should be a no-brainer but TWO LINES MEANS NEGATIVE, ONE LINE MEANS POSITIVE.3. You actually need to follow the instructions: the tip needs to be submerged until the C line shows. This can take around 30 seconds.4. THC levels go up and down daily due to your own personal metabolism. One day you can test negative, the next positive and so on. This doesn’t mean anything is wrong with the tests. You need to be testing negatively CONSISTENTLY for several days (not just one or two) to get a good idea of where you stand.5. These tests are NOT FDA or CLIA certified. Take that into consideration. You should buy several brands of tests at different levels and be sure you are getting consistent readings across tests consistently.Good luck to everyone and I hope these points clears up some of these idiotic reviews.

They do what they say. Easy to use, fast results.

1.0 out of 5 stars Not trustworthy.

I bought these tests to get an idea of when I will be clean of THC to pass my CDL drug test. I smoked concentrates HEAVILY for the previous 8 months, like literally was always medicated, no breaks. After only 2.5 weeks of no use I decided to try one and this test came out negative (and yes, I followed the instructions to the T). That’s quite literally impossible. I have done nothing to specifically detox myself in any “fast” manner, though I don’t really believe in the effectiveness of that anyway.I have had to pass drug tests in the past so I have a slight idea of how long it takes my body to get it out. There is absolutely no way I’m testing negative for such an advertised low of 15ng/ml.I would not trust these.
