Testing is conducted by trained professionals. Once a urine sample is collected from your teen, it is shipped to our lab and tested for the drug categories we ordered at the time of the collection. After the lab testing is complete, the findings are sent to a Medical Review Officer (MRO) for review. If there are any positive drug classes reported, the MRO will contact you directly to see if there is an explanation for the presence of the substance (ie. prescription medications).
