I have a few specific questions, if someone wouldn't mind answering them.

All of the following information is in the DoT document I linked to earlier. I am going under the assumption that I will be tested under these procedures and guidelines.

Apparently the cutoff limit for the initial cannabis test is 50 ng/mL, while the confirmation test is 15 ng/mL.

If the first test comes back negative, would they likely do the confirmation test? It seems that the confirmation test, with it's significantly lower cutoff point, would be used to weed out false positives. If not, why wouldn't they just lower the initial test to 15 ng/mL?


Also...

(a) As a laboratory you must consider the primary specimen to be dilute when:
(1) The creatinine concentration is greater than or equal to 2mg/dL but less than 20 mg/dL, and
(2) The specific gravity is greater than 1.0010 but less than 1.0030 on a single aliquot.

My question regarding those two is, do they test for significantly high levels of each (if possible), or are they only testing for low levels (dilution). In other words, do I have to get these levels "just right", or can I begin creatine loading now, then use gatorade and rolaids to increase the specific gravity enough to beat this part of the test?

According to the document, there are only 4 possible outcomes.

Negative (normal levels, no drugs)
Negative-dilute (no drugs, but creatine and specific gravity below normal)
Positive (drugs)
Positive-dilute (drugs, creatine and specific gravity below bormal)


None of which say anything about levels above normal, so I was just wondering.

Hopefully someone comments on this...if not, I really hope someone finds this information useful. I'll continue to post with questions, issues and of course the results.
