Opiates
- Sample Type
- Standard
- Fasting
- No
- Unit
- ng/mL
This assay screens for the presence of natural opiates, primarily morphine and codeine, in the urine. Within a Drugs of Abuse 5-Panel (DOA 5), it is used to identify the use of heroin (which metabolizes to morphine) or prescription opiates. It measures the concentration against a specific cutoff (typically 300 or 2000 ng/mL). It is vital for identifying substance use disorders or monitoring compliance in pain management programs.

Why Context Matters
False positives can occur due to the consumption of poppy seeds or the use of certain medications like fluoroquinolone antibiotics. Additionally, many semi-synthetic and synthetic opioids (like oxycodone, fentanyl, or methadone) do not cross-react with this specific assay and require separate testing.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
