EtG has been detected in human urine, serum and clipped hair samples of ethanol consumers. The formation of EtG depends on the serum ethanol concentration. WebThe precision and accuracy of the method were assessed at three QC concentrations for EtG (200, 625, 8000 ng/mL) and EtS (100, 312.5, 4000 ng/mL). Based on 11 analytical runs, consisting of three or four replicates, the assay precision (%CV) and accuracy for EtG ranged from 8.4 to 19.6, and 98.4% to 103.6%, respectively. how to run a clothing drive
