Ok have a couple questions rolled into one here. I've done some searching and didn't come up with exactly the info I was looking for so if i missed it my apologies.

Anyway got a Labcorp pre-employment UA coming up in a few days. I've had tests in the past from quest that actually show a number you can lookup that specifies the test NIT something maybe? This one here doesn't have anything to that effect all it says is '5 Panel' for tests requested.

So should I assume that this is 50ng/ml for thc? Which is the only thing i care about.

I've bought a number of First Check home tests different batches and stores. I was relatively clean prior to the 28th of Jan where I shared one blunt probably average quality. Before that I think I was clean since Jan 14 can't remember for sure. Whereas before that maybe smoked 3 times a week. So essentially will be clean for 38 days since the 14th and 24 days from the shared blunt.

All home tests taken with first void beginning stream.
Passed home tests on Feb 10,11,14,16,17

Sorry about the background just thought more info would be better that less info, so on to the questions.

Does the speed at which a negative line develops have any indication about levels? Because in the more recent tests I've seen a fairly solid NEG line(see pic) develop within the first minute, as opposed to five.

Secondly I've read that the half-life of thc metabolites is 3-10 days. As such if i passed my first two tests 10 and 11 days before the real deal is it true that I'm at least at or below 25 ng/ml?

And for the sake of tradition the obligatory, 'Will I pass?'

Also I have two tests left should I bother using them or just return?

Thanks so much the forums here are really a great source of info and stress relief. Cheers from sunny Florida.
