DOT vs NON DOT Testing

Is the acutal testing still the same for NON DOT tests compared to DOT testing, ie: checking for creatine and specfic gravity levels of urine?

That depends on the employer. If the employer opts to have the sample tested at the lab, the likeliness of integrity checks being performed are high.
Still, some employers will opt for an on-the-spot instant test that features additional panels with creatinine and SG being among the panels.

Thanks, yes this NON DOT test is a split specimen collection which is sent to the lab so I'm sure they do all the proper checks.
