Successful sub at LabCorp... I think!

Im a 24 year old female, 5'6'', 123lbs. I smoke about a quarter a week, give or take a few grams. Being completely miserable at my current job, I quit smoking a couple months ago and started looking for a new job. After testing positive at 30 days, then 38, 46 and 54 (while I'm skinny, I'm severely lacking in muscle tone and I eat pretty terribly) I had a friend pee for me a couple times and froze her urine. I still decided to abstain and was supposed to hear back one week after my second interview. After two weeks, I thought I didn't have the job, so I decided to do an internal transfer at work (which doesnt require a drug test) and just started smoking again. A stoney week later, I got an email from the company. I had to fill out an online background check with Certiphi and to go to any LabCorp within 24 hours to do a drug test.

I read everything I could about subbing and practiced with water for a night until I perfected my technique. I had two urine samples in my freezer, and defrosted the less dilute of the two. Unfortunately, an hour before the test when I checked on the urine, the bottom of the jar was full of sandy sediment. I shook the jar, warmed the jar to 100 degrees then shook it again, rolled the jar, etc etc. Nothing would work to dissolve the sediment. Total first world problem, but I have a Keurig, so I didn't have any coffee filters to run it through, nor do I have any nylons that I could have used. I ended up defrosting my other sample, which was pretty dilute and had alcohol in it. We had a few drinks before she gave me the sample. I mixed the two-- a ratio of 50% pee that had been separated from sediment and 50% diluted sample. By the time all of this had been done and the pee warmed, I had to go. Easy sub process-- I didn't have a long wait, I executed well and the sample was accepted. In and out in less than 10 minutes.

Since both samples were from the same person and both were clean, is it safe to assume that the sample will pass the drug screen? I know it runs the risk of alcohol causing a fail, but that's not what I'm worried about.

Thanks yall!
