“If they're inclined to try to sneak something in to substitute or adulterate their sample, they do have a greater ability to do that in a urine test,” Tedrow said. “That doesn't really exist at all in the oral side because the collector is right there in front of them the whole time.”
The other benefit is it's a more discrete process than having someone go into the restroom and bring out a urine sample.
How long will it take to get the results?
It should take less than 24 hours. Tedrow said the lab can usually provide negative results within the same day.
If a positive result is revealed, a secondary confirmation tests is conducted to specifically identify and quantify the drug, or drugs, in question. That takes about three days. This second round of testing provides more specific information about what was found.
“The prevalence of a false positive, because we're doing the confirmation test, is going to be virtually nonexistent,” Tedrow said.
