Laboratory Control Standard definition

Laboratory Control Standard or “LCS” means a sample of reagent water spiked with known amount of the analyte of interest. The purpose of an LCS is to determine whether the methodology is in control and whether the laboratory is capable of making accurate and precise measurements.
