Understanding Lab Tests for Opioid Addiction
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Opioid addiction is a complex medical condition diagnosed through clinical assessment, behavioral patterns, and medical history. While there is no blood test to diagnose opioid addiction itself, laboratory testing plays a fundamental role in monitoring treatment programs and assessing compliance with medication-assisted treatment.
Recommended Test
Methadone and Metabolite, Urine
This test detects both methadone and its main metabolite EDDP in urine samples. Methadone is a medication used to treat opioid use disorder as part of medication-assisted treatment programs. The presence of methadone indicates a person is undergoing treatment for opioid addiction, while EDDP detection confirms actual metabolism of the medication, helping healthcare providers monitor treatment compliance and effectiveness.
