High Urine Cal (5 mL)

The DRI Drugs of Abuse Urine Calibrators and Controls are liquid and ready-to-use. They are prepared by spiking negative human urine with known quantities of d-methamphetamine, benzoylecgonine (major metabolite of cocaine), morphine and phencyclidine. The Low Calibrator is used as a qualitative cutoff reference for distinguishing between “positive” and “negative” samples. When a rough estimate of drug concentration is required, a calibration curve can be established with the Negative, Low and High Calibrators. The High Calibrator also can be diluted with the negative urine calibrator to prepare calibrators with desired concentration
