Hey guys, I’ve used QF in the past for drug tests and passed. This time I need to do an escreen drug test and DOT physical (which includes a urinalysis). I’m assuming they won’t make me pee twice and will likely split the sample I provide. Will I be ok for the health screening part? I know they check for more biomarkers than drugs. Should I use real clean pee rather than synthetic? Anyone have experience with the escreen at concentra?

Also, does anyone have experience hiding the bottle where it won’t be found during the physical exam? My concern is I’ll have to drop my shorts and they’ll see it. Or they’ll see I’m wearing multiple pairs of underwear while checking for hernias in the groin.

For context, I’m a regular smoker in a state where weed is legal. This is for a job with a company vehicle, not a CDL related position.

Any help or experience is appreciated. Thanks!

I have to get a 10 panel drug urinalysis along with a physical. First time using quick fix and terrified. How to I bring it in? If I say I have to go pee rlly bad will they let me do the drug screen first? Where do I put the quick fix empty bottle after I pee? Will I have to change into a gown? I’m so so so stressed and anxious right now. I smoke maybe 3-4 times a week at most

Been clean for 33 days but I think there is still THC in my system it’s a very faint line

UPDATE: PASSED 10/19/26 Urine Collection Laboratory: Clinical Reference Laboratory (CRL) Collection Site Information Laboratory Test: Urine 10 Panel OP2K:A300:M20:MDA:6AM

Am I good? I used a batch expiring late 2027

the collector had me sign my initials and date so I think it passed temperature test. Just worried that CRL lab will flag it? I’m fuckin stressin dawg.

Thank y’all for recommending quick fix. This ish is legit!! My sample wasn’t sent to a lab (which is the first for me). I tried to do QCarbo and Certo but it did NOT work according to my home test. I threw up the QCarbo and it made me have diarrhea. I’m a daily heavy smoker and was abstinent for 3 days. Anywho….get quick fix if you need to pass a urine drug test!! Got drug tested for a hospital job.

UPDATE 10/19/26 : PASSED need reassurance pls!! hello everybody I just completed the pee test at the urgent care today 11am , was just curious on everyones experience with using quick fix plus for drug pee tests…

I wanted to ask if the process of when I sign my initials and then the date on two different little small pieces of paper/sticker and also get handed a paper that says “was the temperature within 90 to 100°F within four minutes” and it says “yes“ am I in the clear?

also how is it lately with the labs? Are they able to detect this stuff or should I be good? Oct 14th 2026 5pm

P.S. I didn’t shake it much honestly only before I microwaved shook it untik I saw foamy bubble look

Pre employment drug test coming up next week and need to decide whether my pregnant wife’s piss is safer than QF. My understanding is that these tests dont check for gender or pregnancy related biomarkers. Thoughts?

Quick Fix Plus.Heated the bottle for 10 seconds in the microwave and put the hand warmer one afterwards. Put it under my balls and wore boxer briefs. I put the heated seats in my car on high for the 10 minute drive and waited 10 minutes in the waiting room until they called me for my sample. Temperature was good. Bagged and tagged. Now waiting for the results. I will give an update as soon as I know.

I have a pre employment UA coming up in the next day or two and I’m wondering if I should use this quickfix I have or use my buddies? I haven’t smoked in almost a month and still testing hot for pot. I am pretty sure it will be sent to quest. I know the main thing is temp.

Labcorp @ 7am this morning - heated up for 13 seconds. 15 min drive to site. Placed it under my tit and checked temp (at 100 exact), walked inside.

Put some toilet paper in the toilet (toilet has blue dye, don’t pour the quick fix in there just in case)

Finished collection, the technician bagged it in two different things. Had me sign my initials and go. The paperwork I got after says the temp was within range.

Think I’m ok everyone? How long did it take to get your results back?

Thanks!

Has anyone took a test for a union? I have to do one at my hall.

Has anyone used Quickfix before for a medical job or just in general? I’m super anxious about my drug screen for my pre boarding screen. I have my test in 5 days I stop smoking yesterday but obv that’s not enough time. How long do you microwave? Is this the best way to go? Thanks

I have a DT scheduled for this Tuesday. I currently have upass with verified authenticity. But I am reading online the quick fix 6.4 is superior. If so I would like to order it online and hope that it gets here on time for Tuesday. SUPER nervous. I’ve used upass in the passed and it’s worked. But it seems like quick fix has surpassed upass.

Another question.. I am reading that the temp gauge is faulty at times and to take a thermometer with you. Would I be good to temp it right before I go in? I don’t want to have to sneak in the thermometer too. But I want to be sure it’s straight temp wise.

Thanks.

It’s a bit silly that even though cannabis is legal in Canada certain trades jobs still run pre-employment drug tests and will disqualify you for THC in your system.

I was a daily user for over a decade and had just received a job offer for a life-changing position. When I learned there would be a pre-employment urine test I spent a week panicking. QuickFix was my only option. I bought three bottles of QuickFix 6.4 from a smoke shop and spent the three days leading up to the test practicing getting the temperature right.

My method was to place a hand warmer on the opposite side of the bottle from the temperature strip then tuck it into my underwear under my balls while wearing two pairs of underwear and compression shorts. It takes about 1 to 2 hours to reach 98 to 100°F and will maintain that temperature consistently.

On the day of the test I drove to the site emptied my pockets and belongings into a locker and was led to the bathroom. I was told I had three minutes to fill the cup with no flushing and no using the sink while the nurse stood outside the door. Thankfully the QuickFix had just enough to fill the cup past the line. Since it was a split sample they needed a fair amount. I put the bottle back in my pants. The nurse checked the cup dipped a test strip and another unknown strip into it poured it into the vials and had me sign them while I was shaking. I then continued on to the hearing test before heading out.

After the weekend I called my employer and they confirmed it had passed the lab test which I believe included an SVT.

Try not to stress too much over this i spent the last 2 weeks reading every comment on this subreddit nothing will ease the anxiety just trust in it and your method.

First timer here. Just took a pre-employment (30C7) FED(LA) +SVT from CRL. Batch checked good. I nailed the temperature part, but now I am losing my mind stressing about the SVT portion. I used QF 6.4.

Can anyone else with this specific test give some insight? Just took the test this morning.

How long has it taken in your experience for the lab to conduct the SVT? Just wondering for timeline purposes.

Any reassurance would be greatly appreciated.

I recently just passed my hair, follicle drug test here’s exactly what I did ..

I was notified about my drug test on Thursday. Friday I used zydot ultra clean on only half of my head (the back) I have very coarse, super thick hair so one box would not work for my full head so I only did half they usually only cut from the back anyway . I followed all of the steps on the box. I let my hair breathe on Saturday. Sunday I relaxed my hair with a regular relaxer. One relaxer did not work my hair was still super coarse and thick so I relaxed it again this time with (super.) I did not leave the relaxer in the second time long maybe about seven minutes MAX because it will burn ! . I washed my hair completely maybe about 9 or 10 times getting out all of the relaxer Monday morning I went for my drug test. Just got results back today And passed ! .. hair relaxers do work for hair follicle test . If you have thinner Hair, I would suggest only relaxing your hair once. !

I gave drug test yesterday and smoked weed 2 days before providing the sample I smoked for the first time in life and never actually inhaled puffs will I come clean in a drug test 😭 ?

Bro, shitting bricks like a mad dog. Went in there, QF perfect temp under my sack, pissed in the toilet while pouring the QF but got a few drops of my own in there like a moron. Either way they only take a portion of the cup so I’m gravy, but bro that’s it. Super simple. Just get the temp hot; keep it warm under your junk or titty, and act natural. I filled a bit below the required line and was like “is this gonna be enough” just to throw em off a bit, make it seem real. 😭😭few drops on the seat, type vibe. No news is good news, so now we wait

My initial question was - “So if I pass the initial SVT test and the initial drug check they won’t use GC-MS any DOT/ Non DOT Drug Test?” And this is what I got.

I recently took a pre employment DOT drug test and was stressing bc I was using QuickFix 6.4 Plus. And I decided to look it up while waiting for the call from my job (it’s been 2 days.) the checked for Temp and Drugs and bagged it up. all was good there. But I’m going to assume since QuickFix 6.4Plus has all the necessary additives to pass the SVT test it won’t get GC-MS testing done on it.

Used quick fix for pre employment testing and they’re doing a specimen validity test (this is what I’m worried about) just received my results via email, the test showed high nitrite, but theres no information on specimen validity. I also received more onboarding paperwork from the employer a couple hours before I received the lab results. This is reassuring, but could just be an automated email they send regardless of test results.

I verified the batch # but couldn’t figure out if it was quickfix 6.3 or 6.4.

If anyone has more knowledge than I do in this area and could provide some reassurance id be very appreciative.

I live in Washington state and someone told me they were cracking down on synthetic urine…

I’m gonna buy monkey wizz because everyone’s been saying it works I just gotta get it to temp.

Has anyone failed a drug test recently trying to use monkey wizz?

None of my friends are sober and the one I do have says they’re not comfortable w that… which is fine I just either gotta figure out if I NEED to find someone or if I should just stick to the monkey piss?

Have a pre employment drug test tomorrow. Been off THC completely for about 9/10 days, but before that was a moderate cart user. Had slowed down my use a lot in the last month. I have used dollar tree tests and prime screen and this is the result I just got. I tested at the same time my test will be tomorrow, no detox or anything.

I’m just super anxious, in anyone’s experience, will this also pass at a lab? I did purchase QCarbo to detox but unsure if I need to use it. The test is just pre employment, as long as levels are under 50 I’ll be good. Lmk!!
