Unauthorized drug use in the US Army based on medical review officer evaluations.

This article examines the US Army's Medical Review Officer (MRO) drug positive urinalysis evaluations from 2009 through 2012. We retrospectively analyzed nearly 70,000 MRO results by year, drug and Army component. Of the MRO reviewable positive results, the Army's unauthorized drug positive rate was 22.

Drug positive rates for the Army, Army Reserve, and Army National Guard from fiscal year 2001 through 2011.

Objective: To examine the overall and drug-specific positive rates of Army urinalysis specimens tested from fiscal year 2001 (FY01) through FY11.

Methods: We analyzed annual Army Forensic Toxicology Drug Testing Laboratory results from FY01 to FY11.

Results: From FY01 to FY11, the Army's positive rate was 1.

Retrospective study of urinalysis for dl-amphetamine and dl-methamphetamine analysis under current Department of Defense guidelines.

Under current Department of Defense (DOD) directive, the laboratories certified to conduct urinalyis testing in support of the DOD Drug Deterrence Program are required to conduct dl-isomer analysis on all specimens that confirm at a concentration greater than 500 ng/mL methamphetamine (METH). Although the same cutoff concentration is required for amphetamine (AMP) reporting, there is no requirement for dl-isomer analysis of AMP-positive specimens. Of the 894,823 specimens screened by the Army Drug Testing Laboratory at Ft.
