Adderall false positive drug test

Determining the source of the methamphetamine is an important next step and is not always as straightforward as it appears. Background Methamphetamine increases synaptic dopamine, primarily by stimulating presynaptic release rather than by blocking reuptake. Small doses have central stimulant effects without significant peripheral actions.

Public Understanding of Chemistry: Chemistry and its social-political-economic context continue to change. Chemistry and chemistry-based technology that impact our lives make for the complexity and controversy of life and set the stage for thinking about public understanding of chemistry. On December 22,a urine sample UA was collected from an ex-convict suspected of methamphetamine use. When the test came back positive, he lorazepam concentrate sl administration subsequently charged.

With the prospect of a violation of his existing release looming, he reached out to a consulting chemist, Dr. He claimed to have not previously tested positive for any Drugs of Abuse since drug test was paroled. In the document faxed to Dr. Manuta by the Defendant, he described the medications that he was taking at the time, including prescriptions.

The nanogram is a metric mass unit equal to one-billionth of one gram 10 -9 gthe mass of a typical human cell [1]. With the testing located in California, the urine samples must be collected and preserved in accord with accepted protocols and standards prior to being shipped drug test the facility. CDOC personnel need to properly package these urine samples, per the accepted methodologies, in order for the test results obtained to be can family physicians prescribe xanax meaningful.

Drug test of dextroamphetamine C 9 H 13 N. Structure of methamphetamine C 10 H 15 N. Structure of pseudoephedrine C 10 H 15 NO. According to ImmunoChemistry Technologies, LLC [3], the immunoassay methodologies offer rapid identification of specific molecules. An advantage of ImmunoChemistry Technologies is that many samples can be analyzed in a day via these techniques. False-positive test results can be obtained via the strength of white valium tablets identification techniques such as IA.

A check on a positive sample with GC-MS enables one to have greater confidence in the test result [4]. Redwood Toxicology Laboratory RTLthe laboratory used for the urine testing, indicates that approximately 85, urinalyses are done each week for Drugs of Abuse. This throughput level suggests that immunoassay methods are used at RTL [5].

This huge throughput corresponds to 12, samples per day, samples per hour, and more than 8 samples per minute. Less than 10 seconds per sample appears to be the usual analysis time. Review of the analytical results may not be done prior to sending them to CDOC. RTL has two methods for "drug test" methamphetamine in urine. This level is less than the cut-off level that the RTL methods noted in the previous paragraph can detect.

There is uncertainty on what was actually measured in the positive test reported by CDOC personnel to the Defendant. Methamphetamine C 10 H 15 N bears similarities to dextroamphetamine in its chemical structure drug test. Mass Spectrum .25 mg ativan daily Methamphetamine. Mass Spectrum of Pseudoephedrine.

The similarities between these three chemical structures are striking. As a result, there is, to a reasonable degree of drug test certainty, some doubt cast regarding whether the "drug test" methodologies used by RTL personnel are sensitive enough to consistently and reliably distinguish between these very similar molecules. The half-life of pseudoephedrine is about test drug 6 hours.

Depending on the pH of the urine, it can take up to 16 hours for pseudoephedrine to be eliminated in drug test [11]. Based on the chemical structure similarities between methamphetamine and pseudoephedrine, one would expect their respective mass spectra to positive adderall false alike. It would require an experienced chemist to distinguish between these molecules, based on a thorough review of immunoassay test data.

The Defendant provided urine samples when requested. Based on the 6-hour biological half-life of pseudoephedrine, it is possible that the Defendant had residual pseudoephedrine in his urine concurrent with producing this test sample. In this instance, the identification propecia after prostate cancer diagnosis code pdf methamphetamine when residual pseudoephedrine is present results in a false-positive.

Likewise, the prescription medication Adderall XR has amphetamine in it. The mass spectrum of amphetamine should be obtained when this urine sample is analyzed. In this instance, the presence of amphetamine is not a true false-positive; rather, it is what one expects to observe from a medication where amphetamine is one adipex 427 for sale its ingredients.

Given the similar chemical structures of dextroamphetamine in Adderall XRmethamphetamine, and pseudoephedrine, the immunoassay technique presently in use may not be consistently and reliably sensitive test drug to distinguish between the subtle differences in these molecules. As a result, a false-positive for methamphetamine is not an improbable outcome. As the mass spectra of methamphetamine and pseudoephedrine are nearly indistinguishable, this would be an example where a false-positive could occur.

The mass spectrum of methamphetamine is, to reasonable degree of scientific certainty, what can result from this matching process. Also, the standard adult dose for pseudoephedrine is 60 mg. There are six orders of magnitude between mg and ng. Such concentrations would have, to a reasonable degree of scientific certainty, saturated the sensitive detector.

Moreover, had the parolee been a habitual user of methamphetamine, he would have, to a reasonable degree of scientific certainty, tested positive for methamphetamine more often than this one time. When all of the information presented here is read with understanding, it is clear that false-positive results were obtained for methamphetamine and amphetamine in the urine sample collected.

The Defendant was found not morphine and adderall interaction at his January 12, hearing. His curfew ended and his ankle monitoring device was removed at that time. The CDOC appealed the initial exoneration. The parolee was released from custody when the appeal was unsuccessful. He is now a free man. Cate Manuta Chemical Consulting, Inc. All rights are reserved.
