ETG 2000ng/ml Calibrator

The DRI Ethyl Glucuronide Calibrators and Controls are liquid and ready-to-use. They are prepared by spiking negative human urine matrix with known quantities of Ethyl Glucuronide. The DRI Ethyl Glucuronide 500 ng/mL and 1000 ng/mL Calibrators can be used as a qualitative cutoff references for distinguishing “positive” from “negative” samples. A rough estimate of drug concentration in the samples can be obtained by running a standard curve using all calibrators and by quantitating samples off the standard curve. The controls are sold separately. Each laboratory should establish its own acceptable control ranges
