The 5 Panel Rapid Drug Screen will qualitatively determine the presence or absence of 5 classes of drugs and/or their metabolites in your urine. This test is considered a screening tool only. Positive results are considered presumptive, and should not be interpreted as definitive evidence of substance use without additional laboratory-based confirmation testing. Laboratory confirmation of presumptively positive instant drug test results is available if necessary. Additional charges for laboratory confirmations may apply.
