How many ounces of urine must you pee for an ETG, what is considered inconclusive?

I took an ETG just now, but was not very much, I even pointed it out to the lady, but she didn't care. Can that little amount help me or go against me?

Depends on lab and the PO, if they feel you gave a little on purpose it can go against you.
Normally there is a line on the cup and they want it filled to at least that point.

Do you normally not urinate much ?

I do. I am nervous because I got a New Years random, and I never drink, but I went to Vegas and did, my last drink was Tuesday at 5pm (glass of Chard), As soon as I found out yesterday that I needed to pee today at 11am, I have since drank 1 gallon of water, took 2 detox shots, exercised (cardio for 25min) did a salt water flush, ate a big meal, took 2 creatine pills 2 hours before testing along with 1 monster. I urinated a lot! And then my piss test came, and I barely got anything out, because I spent one second eliminating my urine away from the cup, before peeing into it. My urine was very concetrated and looked very good, just a tad worried. Any advise or knowledge on what I've wrote.

Probably fail... people think they can cheat on tests and they are pretty good about catching people trying.

Anything like that registers as a fail... particularly since sometimes if they had done nothing they might have passed.
