Is it the same for dot drug testing ? I would think a dot drug test would be more sensitive

[@exploroproducts]

50 ng/ml is the official cut off level. If the company wants the confirmatory test then it is 15 ng/ml . Otherwise it also can be 15 ng/ml if the company says it before the test.

I've been using home test for over 3 years as a hemp smoke and I can make this simple for you. 2 solid rosey lines mean you are good to go with not much to worry about for an extended amount of time or indefinably if you test at least 5 times spread apart in 12-24 hours with below minimum fluid intake. Minimum below fluid intake? Dehydrated urine is your worse enemy when it comes to drug test. When you are dehydrated, you body is drawing from every recourse in your body to keep you conscience. One recourse is your fat cells where everything you consume is stored and bleeds into your blood stream, then through the liver and in to your bladder around the clock nonstop. If you test negative with very dark yellow urine which don't necessarily mean your pee is dirty, you are clean. Now a faded line is simple as this... It is a pass, but it is a warning. It tells you that there is THC metabolites present but not enough to trigger a total fail. With that said, referring to earlier in my comment, as time passes throughout the day, if you test yourself on top of the hour a few times, that line may stay consistent OR it may turn more and faint meaning that you still have a great deal of THC stored up which will eventually become a no liner, a fail. A faint line is good for up to 3 hours if your are gearing yourself up for a pre-employment drug test, but you must stay above hydrated with a B vitamin like B12 to keep your urine yellow and urinate as much as possible before you take your test and with just water, nothing else. Drinking a liquid with substance such as any type of tea could do exactly what you wanted but at the wrong time...Flush, but you could potentially flush THC in to your sample.

Hi! I’m 31F 160 lbs, smoked nightly for many years, mostly flower and I quit for 29 days, was showing negative after only a week. I then smoked a couple of days (Monday Wednesday and Saturday) very small amount and am testing negative. Is it possible to be clean this quickly, are these accurate?

[@exploroproducts]

Hi! Given your details (31F, 160 lbs, smoked nightly for years, then quit for 29 days), it's possible to test negative quickly due to several factors: 1. Metabolism: You might have a fast metabolism and lower body fat percentage, which helps in faster THC clearance. 2. Hydration: Staying well-hydrated can dilute urine, potentially lowering detectable THC metabolite levels. 3. Small Amounts: The small amounts smoked recently might not have been enough to raise your metabolite levels above the test's detection threshold. Your negative results seem plausible considering these factors. However, individual results can vary, so it's always good to consider these aspects. Additionally, for the most accurate results, ensure that you're taking the tests using your first morning urine. This sample is usually the most concentrated and provides the most reliable results.

Can i trust exploro brand tests? I fail on primescreen for 15ng but I pass consistently on exporo 20ng. I even passed a self test lab test at 15ng. I dont know who to believe!!

[@exploroproducts]

Hi dear, our tests THC Urine Drug Tests has a cut of level of 50ng/ml and if you pass it, you should be good to go as this is the official cut-off level of THC Urine Drug Test (50ng/ml). Time when you have to worry about 15 ng/ml cut-off level is either if you fail the 50ng/ml THC urine drug test or the employer tells you that this is the cut-off level of the test that you will need to pass. In your situation we suggest: 1. Make sure you do your test with the first morning urine as it is the most concentrated and will show the most accurate results. 2. Try multi level test, so you can see more clear where you stand: www.amazon.com/Exploro-Sensitive-Marijuana-Substance-Dip-Cards/dp/B0C69Q8GR8/ 3. If you still not sure and want to feel more secure, you can always do the lab test that will tell you the exact concentration of THC metabolites in your system.

[@parkerarrington9851]

I don’t understand reason two if less of the drug is there wouldn’t that mean u r farther away from the threshold. So based on reason one the line should be more solid

[@exploroproducts]

You're correct. If someone initially tests positive and then drinks a lot of water or uses detox products to dilute their urine, they might see a faint line on a subsequent test. This happens because the concentration of drug metabolites in the urine has been reduced below the threshold level. However, typically, a faint line, regardless of previous results, still indicates a negative test result because it signifies that the concentration is below the test's sensitivity limit. Does this help clarify things for you?

[@billyjoe2799]

Does the test line have to go all the way across?

[@exploroproducts]

No, not necessarily.

[@backwoodz7160]

My line is super faint almost doesn’t look like it’s there but you can see two lines. Makes me nervous if it will pass or not

[@exploroproducts]

When the "T" line on the test is faint, doesn't matter how faint it is, it is still concidered negative result. If you still have time before your initial test, repeat the testing for a few more days with the first morning urine and see, the line should slowly get darker every day. Faint line appears when THC metabolites in your body is just a little less then the cut of level of 50 ng/ml, but it is still considered a negative result.

Hey if only had one puff vape of thc and that was 14 days ago but only one and I did easy@home drug test and it was negative wil I pass the real urine test

[@exploroproducts]

Hi, as we can not guaranty for other brand tests. If the test had 50ng/ml cut of level and you didi it with the first morning urine, you should be ok. What we would recommend is do the test again for a few next days and if it stays negavite for all of them, you will be good. Remember it is important that you the test will have 50ng/ml cut of level and you do it with the first morning urine.

[@exploroproducts]

A faint line on your test usually means it’s negative, so it seems like you’re on the right track! We hope your test went well. As for the next time - keep staying hydrated and avoid heavy exercise right before your official test to minimize the chance of THC metabolites appearing. You’ve done a great job staying committed - stay positive!

I recently failed a 14 panel drug screen and it was positive for Fentanyl. I don’t take any drugs so I am very confused about this, now we are just waiting for the actual lab results. My question is why would it be positive for Fentanyl and what could have caused it if I don’t take neither drink alcohol at all.

[@exploroproducts]

It's understandably confusing to get a positive result for fentanyl if you haven't taken any drugs. False positives can happen due to the interference of other medications like trazodone, risperidone, paliperidone, or iloperidone, which might be mistaken for fentanyl by the test. Drug tests usually look for similar chemical structures that might mimic fentanyl metabolites​. If you could share what did the lab find, it might be helpful to others.

[@anthonynumi3297]

If I pass a 300nm with a faint line how long would it take to pass a 150 nm?

[@exploroproducts]

If you are saying that you pased the test with 300ng/ml cut-off level with faint line, and asking when it is possible that you would pass the test with 150 ng/ml cut-off level, it is actually hard to answer as it depends on a lot of different factors like - when was the last time person had THC, how often person has been using it, for how long, how the body metabolise THC and so. So it could take from 2 weeks to up to to 1-2 moths.

[@exploroproducts]

Hi there, we would suggest you to do the tests a few more times (before the test) with the first morning gurine and see if the situation is getting better. The possibility here is that the THC metabolites in your body is around the cut-off level and that is why it is possible to see and positive and negative result. And that is why we suggest to do a few more tests with the first morning urine, to make sure the test is negative.

Why would both the T and C lines be super faint?

[@exploroproducts]

Common Reasons for both 'T' and 'C' lines to appear faint: - Low Concentration of THC: If the concentration of THC metabolites is near the cut-off level, both lines might appear faint. - Diluted Sample: If the sample is diluted, it can result in fainter lines. - Improper Storage: If the test has been stored in conditions outside the recommended range, it might affect the results. - Sample Collection Issues: Insufficient or improperly collected samples can lead to faint lines. - Expired test: The test could be nearing its expiration date. In any case, check all these possible reasons, and repeat the test the next day with the first morning urine.
