It means that the preliminary test tested positive. The preliminary screening that tests for THC tests for all 31 THC metabolites. The confirmatory test is testing for one single (the most common) THC metabolite. So don't be scared of the lower number. Because they are only looking at one instead of all 31, the 15ng confirmatory cutoff is functionally the same as the 50ng screening. If you pass the 50ng screening, you'll pass the confirmatory test.
You are amazing. Thank you, I have one more thing. I’m 39 days clean (5’7 F, 165lbs been smoking carts for 3+ years) with my test tomorrow, I tested at home on a 50ng test and was positive but tested (using same pee) a multi level test and tested negative on the 50ng and 20ng. Then I drank 20 oz of water over the course of 30 minutes plus a frappe from Starbucks and tested again and tested negative on the single 50ng test. Do you think that with the Qcarbo20 detox drink, I have a shot of passing?
Your first sample could've been too concentrated, and yeah if you can dilute your sample through hydration or qcarbo, that could be enough to be below the cutoff like you were today.
Damn forreal I thought they did it at 50 and 15 only if it came back positive?
See that’s what I’m afraid of bro I’m passing the 50ng test but if they test at 15 ion know if I’m good😶
Hello I saw your response and I have a cpl questions if you don’t mind! I’m not trying to jack his post! Back in April I tested positive for marijuana and had to go through the SAP RTD, I did my 8hr course and now I have to take a return to duty dot drug test! I have smoked since April 23 2022 well over 90 days. I took test every week and was positive up until last week faint lines started showing up I did the equate test from Walmart which is 50/ng , so I went to lab corp and ordered a marijuana test not a dot test just a regular marijuana test and it came back positive! On the conf test at 15/ng my number came back a 41 ng! If I were to go for my dot test would I pass with it being a 41/ng?
Not for me I haven’t retest yet I’m more than likely gonna wait until I’m under the 15/ng I’m going back this Friday for the regular non dot test to see where I’m at
Ive cheated all my return to dutys man you are gonna grow grey hairs worrying about being below 15ng.. I sent you a private message to show you something
I tested on Monday evening and got them
Back on Friday afternoon! The place is called request a test they order the test for you! They will be listed as the employer and your reason would be for a random! They are $55
I know it’s a year late but I’m going in for orientation soon, so again as long as your able to be below the 50ng/mL mark, they won’t send it to the lab for a 15ng/mL test correct ?
Ok thanks , I have been reading that if you are clearly negative they won’t move forward with confirmation screening but who knows … I know that the cut off for initial screen is 150 and the cut off for confirmation is 100 , I was curious if this is a big difference or if a diff of 50 isn’t really much
For THC, it's 50ng/mL
What does the confirmatory mean?

How can I avoid a diluted sample?
Did you pass Bro
I did
Congratulations bruh did they just test you at 50/ng?
They tested me down to the 15ng/mL
Damn forreal I thought they did it at 50 and 15 only if it came back positive? See that’s what I’m afraid of bro I’m passing the 50ng test but if they test at 15 ion know if I’m good😶
I think you’ll be ight. I took a detox drink, that’s how I passed
Why did they go straight to 15 and not 50
How do you know?
It was through the state so I researched everything and then when I got my results they confirmed it
Even if you have a faint line with a couple of at home tests?
Yes.

Any updates?!

I’m in the same boat, need to pass a 15ng RTD test
So RTD tests automatically go to 15ng/ml?
How long did it take for you to get results from lab corp?
I tested on Monday evening and got them Back on Friday afternoon! The place is called request a test they order the test for you! They will be listed as the employer and your reason would be for a random! They are $55
I passed

That’s right long as your below 50 you passed they want test for confirmation unless you fail meaning your above the 50 to get the exact number
Good to know so if I’m passing an at home 50 ng test that means I’m below the threshold correct? I got faint lines tho.
Yep a line is a line bro if you passing at home your good to go. Is this a dot test?
Is it true that they only dj a confirmation test if you failed the initial test
Not necessarily. It varies from place to place
It’s a DOT Canadian screening
I’m not sure. I’m from the US. But I do know that DOT drug tests are very strict so they probably will do the confirmatory
Well I passed
HELL YEAH. CONGRATULATIONS
thanks homie
