Recent Pre-Employment Drug Test (Substitution w/ Synthetic)

[Burnt Toast]

i need some help myself i have spent a week trying to research everything i can to decide my course of action i am6'3 265 lbs and a little overweight. i have a pre employment test for an oilfeild job. i am pretty sure it is a dot test. first question is it possible to detect synthetics through this test or is it best to strip and test days prior. i was gonna buy the same product this threads about but i am freakijg out. any help would be cool.

Under DOT regulations, a "non-human" sample (aka "substituted specimen") is determined by checking the creatinine and specific gravity. Below is the criteria applied under § 40.93 of the DOT regulations (which is still current as of this writing)..

Subpart F - Drug Testing Laboratories
§ 40.93 What criteria do laboratories use to establish that a specimen is dilute or
substituted?
(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.
(b) As a laboratory you must consider the primary specimen to be substituted when the creatinine concentration is less than 2 mg/dL and the specific gravity is less than or equal to 1.0010 or greater than or equal to 1.0200 on both the initial and confirmatory creatinine tests and on both the initial and confirmatory specific gravity tests on two separate aliquots.

As long as the synthetic batch is unexpired and had been kept away from direct sunlight, it will pass the validity checks permitted under § 40.91 of the DOT regulations.

For peace of mind, you can always test your synthetic batch with a validity test strip to make sure the creatinine, S/G, pH, etc are all within acceptable ranges. These test strips can be found online cheap by doing a Google search for "drug adulteration test kits".
