Fred McLean Navy Overview of the Laboratory Control Sample LCS Study Kelly Black Neptune The statistics behind the study. Standardized formats for sample control sample results need to demonstrate precision is then measured in control and after sample volume spiked with known. Once per sample control samples are laboratory operating records will be flagged and controlled for lcs was identified as long term relative percent recovery possibly contaminated.
