  • Need help fraudulent urine screen analysis

    Could anyone tell me if I had a concentration level of 300ng/ml of methamphetamine,approx how much meth would I have to do in a 16hr time frame prior to the drugscreen and is it possible to be positive for 300 ng,/ml of methamphetamine but be negative of any amphetamines.

    Blood tests can detect meth most quickly after it's been used, typically one to three days after last use.

    Meth can be detected in saliva for one to four days after the last use.

    Meth is typically detectable in urine for one to four days but may be detectable for up to a week after heavy, chronic use. A urine test typically shows a higher concentration of meth than other drug tests because the drug's metabolites are eliminated through urine.

    A hair follicle test can detect meth in your system for up to 90 days.

    Testing to identify specific drugs, rather than classes of drugs, is needed to confirm a positive urine drug screen for methamphetamine. To ensure clinicians can accurately interpret your drug screen results, always disclose any prescription or over-the-counter medications you are taking.
