I am currently preparing for the implementation/validation of urine drug screen cup testing in our Pain Management Clinic. I assume that I must also validate the adulterant testing. Is QC available for the adulterant portion of the drug screen? What is the best way to validate the adulterant tests (pH, SG and CRE)? I know that I may use a UA dipstick to validate pH and SG, but what about the Creatinine? Thank you!
