To ensure the validation of urine drug testing results employ an external control, such as the iScreen Control Negative with 3x cut-off
The clinical controls are designed to work with most of our urine drug tests excluding adulterants. In both 5mL and 20mL options, the liquid solution vials are convenient for any office.
Controls are available in both positive and negative formats and are used to demonstrate the results of urine-based drug tests. The negative control will yield expected negative on each panel.
