1 Panel Drug Test for Opiates (OPI).

Described as a rapid, one-step urine drug test, this product is designed to test for illicit substances from human urine in a one-step operation. This product is an excellent solution for testing loved ones at home or for employees in the workplace. It’s simple to administer and easy to interpret. Parents use these at home when they need to test their loved ones regularly. These quality one-panel drug test kits conform to NIDA guidelines with accurate cut-off levels giving you the confidence of testing, with consistently precise results every time.

Explanation: The process requires the absorbent finger to be dipped into a urine sample for the device to work.

Therefore, the presence of a metabolite for Opiates is a good indicator that a person has used that substance.
