Home Drug Testing Tips & Advice
We are passionate about what we do and our goal is to make drug testing simple. With that in mind, we thought it would be helpful to explain a few things you should know to avoid getting a false-positive result. If you have ever thought your positive drug test result was a mistake, you could be right.
There are a few products that can cause a false positive on a THC test. Vitamin supplements, especially ones containing riboflavin can cause a false positive. Most supplements are made synthetically, but some companies produce riboflavin from hemp seed oil. Ibuprofen can also cause a false positive for THC, barbiturates, or benzodiazepines. So if you’ve got a headache just before you take a home drug test you should grab some aspirin or acetaminophen instead.
Some people claim second-hand smoke will trigger a positive drug test result. This rumor is false. You would have to be in a very enclosed space with someone smoking heavily non stop to test positive for THC.
You might have heard about the rumor about poppy seeds and positive drug test results. People say if you eat poppy seeds, like on a bagel or in a muffin, you might test positive for opiates. Well, this rumor is true. Poppy seeds actually contain trace amounts of opiates, like opium and codeine. Opiates can usually be detected in urine for up to 48 hours, so you should avoid eating anything with poppy seeds in that time frame.
Cold medicines, while tremendously helpful when you have congestion or sore throat, can lead to a false positive for amphetamines. This is because the primary ingredient in most cold medicines is Pseudoephedrine, which is a synthetic amphetamine and is often used to make drugs like meth.
Thanks for taking the time to read this post. We hope it provides you with more knowledge, so when you go to use one of our home drug tests, you can be assured you’re getting the right results.

“I really like this drug test (Utest-O-Meter). I used a detox (desperate times) and then followed up with this test a few hours later. . . the test was useful in verifying that the detox did not work.”
“This company is amazing. I got the test Saturday around 7pm and took it at 10pm. I emailed them that same night and got a reply within minutes. Highly recommend trying this one to figure out where you are.”
“I was a little skeptical ordering a test online to check for a pre-employment drug screen. The first time the lines were a little faint, so I tried again. When I contacted U-TEST, I was called by the owner of the company. They have been around for 26 years. I also received emails on the correct way to perform the test.”
“Don’t waste your money on $15-$20 tests like the ones at Rite Aid, CVS, or Walmart. This test is highly sensitive and measures down low to 15ng. Accurate and beneficial to have, always have a couple on hand to test yourself before anything.”
“I had bought a dollar store test when I found out on a Thursday I had a pre employment test coming up the next Monday. It was a 50ng that produced a very faint line. So I ordered this test and it was here on Saturday. I took it the next day and it was easy to read and gave me a clear negative, all the way across. Trusted it and passed my lab test the next day.”

“The customer service is amazing and very responsive. . .the product works. They also gave me tips around what to do to get the best baseline of where you stand. AWESOME PRODUCT.”
“Good news. I am below the 20ng on day 138. It took a long time because I am overweight, old, smoked concentrated oils, and have been on bed rest the past 11 months due to bad injuries. And two surgeries. Thank you for [the] fast delivery and great product.”
“This product saved my job and I highly recommend using this if you have any upcoming drug test for work.”
“Worth the price & gave me the results I needed. Sensitivity is very good, making it lower than a normal urinalysis test is very beneficial and lets you feel confident about the results either way.”
“This is hands down the best test on the market. It really gives you the reassurance you need to know you will pass a lab test. I passed this and a few days later passed my pre employment LabCorp test.”
“Super easy to use, love the discreet packaging they use. . .Passed with flying colors at home and passed my UA for a new job. I had about 2 weeks clean. Extremely quick results, less than a minute.”
“Have brought these several times and they work as described. Please follow the directions. If you were a heavy smoker like I was it took me over four months to rid the THC out of my body (been smoking over 15 years, the first time clean).”
“I like that if this test is negative then I know for sure that the lab test will be negative. I also like that you can send a picture of your results to the company and they will read them for you if you're not sure of your results! Love this product and I will buy again 👍👍.”
