An opiate screen is a blood test that looks for opiates, a group of medicines and drugs that come from the opium poppy or are made to act like it. It is ordered to check for recent use, to help assess a possible overdose, or to monitor someone in treatment or under medical supervision.

What it measures

  • Morphine — A common opiate used for pain; often the marker the test is built around.
  • Codeine — A pain medicine that the body converts into morphine.
  • Heroin — A drug that breaks down quickly into morphine in the body.
  • Hydrocodone — An opiate pain medicine sold under several brand names.
  • Oxycodone — An opiate pain medicine, also available in long-acting forms.

Who it is for

The test is usually ordered by an emergency doctor, a pain or addiction specialist, or another clinician when recent opiate use needs to be checked. It may also be used as part of a workplace or treatment program that requires drug testing.

Preparation

No fasting is needed. Tell the person drawing your blood about any opiate medicines you take, including prescriptions, so the result can be read correctly.

Results and what they mean

Results are usually reported as positive (opiates found) or negative (none found), sometimes with a number for each substance. A positive result does not by itself mean misuse, because prescribed medicines and some foods can cause it. Only a clinician can interpret the result in your situation; this is general information, not medical advice.
