Instant 20 Ng/ml Ultra-Sensitive Marijuana Drug Test: Two Individual Tests

I decided to try these lower sensitivity ( 20 no/mg test ) drug screening dip test for the metabolite of the THC-COOH in my system and compared it with the Ütest brand of the same 20 NL cutoff that I reordered in spite of the fact that I gave them a 1 star review as they were defective and not acurate. The "THCCheck (my ) brand is pictured on the left and the cheaper made and unreliable Ütest brand is in the right. The THCCheck dip test by far was the better choice, was completely accurate & much easier to read results. The product was also made with better quality material and was much larger and easier to handle then the inferior Ütest THC low sensitivity 20NL dip test! I have tried several other brands of the THC-COOH dip testing for home use drug screening and my favorite "50 nl standard cut off test is the "Easy@Hime" brand. I only wished they made the lower cut off testing as I use them for checking my CBD oil products! BTW, FYI, The NuLeaf CBD oil ( btw "Leafly.com recommends thier product line ) is the best on the market but if your a regular CBD oil user and consuming high mg per day, you most likely will test positive at the lower sensitivity level THC drug screening. But it clearly states that there is 1.6 mg if THC per 50 mg dose of their CBD oil. So it's not like their hiding the fact! Also FYI, "DiamondCBD" oil & gummy's is complete garbage as well as "Apothecanne" brand of CBD oils & creams, don't waste your money!

Very sensitive. Most over the counter testing kits drop to about 50ng. on a test. We all have natural THC in our bodies anyway. This one is like the Urine cup version, dropping to 20ng. The Feds and the State test at 20ng, most employers will test at 50ng.If you've had less than 3 puffs in the last 90 days then you really have nothing to worry about anyway, especially if you drink a quart of water two hours prior to actual testing and if you waited three days then you don't even need to purchase this test kit. You're Good-To-Go!When your negative you'll see two lines one very dark and the other very faint, this is good. Other kits will show you two very dark lines, these are the cheap Dollar Store variety. For the money this is the best you can do without paying $20.00 at CVS or Rite-Aid for a cup. Good luck my friend. We all know it's BS anyway.

I was sent expired tests. Completely of no use to me. Can't trust if the results are accurate.

Got them for the BF, he hasn’t smoked in a couple months and only smokes once or twice a month, but he was a HEAVY smoker for years until end of December, is heavy set and has been working to lose weight. Since it is stored in fat cells we heard that burning said fat can increase THC levels, so we wanted to test before a new job screening just to be safe. Both came back with faint lines, the first morning pee test came back fainter than the midday, perhaps a little less than half the coloration of the control, as expected. He passed though, so these must work.

Rating at a 3 star for now. I last smoked almost 40 days ago. Got a very faint line in the test portion on the first void of the day.Previously taken a walmart equate cup test at 50ng/ml 4 days ago and passed with a THICK solid line. These 20ng/ml dip tests are the faintest pass lines i have ever seen. I will purchase again in 20 days and leave my final review because i am not sure they are very good or i am somehow still "dirty"As for my smoking history i was a 4x week user up until 5 months ago, then abstained all of december, ate a few edibles in january, smoked once the first week of february. I am 5'10 175lbs and have been hitting the weights 4-5x per week the last 5 years. I do not do much cardio.

This is a very simple drug test for THC. I received two testing sticks for below 20 ng/mL. I am clean with no drugs in my system. The test is simple. Pee into a small cup, dip the tip of in and wait 10 seconds, remove, lay flat and wait 5 minutes to see either an invalid result, positive or negative.This should be great for anyone worried about an upcoming drug test for an employer, or maybe someone with a teenager in their home they suspect of marijuana use.

Not knowing whether or not the test produces accurate 'positive' readings means that I shouldn't rate this a full five stars, but it certainly accurately showed that I was negative for metabolites. This would be a great add-on purchase for anyone using 50ng-cutoff tests to personally check that levels are dropping as expected and/or graph timelines for future reference of likely positive results based on consumption.

Used these for our teenagers. Just wanted to be aure these kids are ataying on the right path. Quick and easy to use. Seem to test accurately, the wife and I used to verify. Results are easy to read and directions were easy to follow. Would recommend and buy again.
