Cut-off Levels

militarydefenselawyers323DOD and urine testing laboratories have established “cut-off” levels.
Samples which give test results below these cut-off levels are reported as negative. A sample is reported as positive only if it gives test results above the cut-off level during both the screening (every positive screened twice) and the confirming test.
