Opioids and their metabolites

Does a drug test detect Morphine?

Yes. Morphine is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 50 ng/mL. The LabX 12-panel screen includes a Opiates line designed to pick up Morphine. A screen is presumptive; adding laboratory confirmation identifies Morphine specifically.

What is Morphine?

Morphine is a naturally occurring opioid and one of the oldest pain medicines in use. It is also the compound the body produces when it breaks down heroin and, in part, codeine.

Also known as or found in: MS Contin.

Medical use

Morphine is prescribed for moderate to severe pain, including pain after surgery and pain related to cancer, in short-acting and extended-release forms.

How LabX tests for Morphine

Morphine is measured by liquid chromatography with tandem mass spectrometry (LC-MS/MS), which separates the compounds in a sample and identifies each one by its mass. That is different from a rapid screen, which reacts to a family of drugs and can occasionally react to a related substance. The laboratory reports Morphine as detected when its concentration is at or above the cut-off of 50 ng/mL, within a reportable range of 50–10,000 ng/mL. It is one of 16 compounds in the opioids and their metabolites family on the 76-drug confirmation panel.

Detection window

The laboratory's confirmation report lists an approximate detection window of 1-3 days for Morphine. Treat that as a rough guide only: how long any compound stays measurable varies with the amount taken, how often it is used, body composition, metabolism, kidney and liver function, and hydration. A laboratory result cannot be used to work out when a substance was taken.

Screen versus confirmation

The LabX 12-panel screen includes a Opiates line designed to pick up Morphine. A screen is presumptive; adding laboratory confirmation identifies Morphine specifically.

Worth knowing

Morphine on a report can come from prescribed morphine, from codeine, from heroin, or in small amounts from poppy seeds. The heroin-specific marker 6-MAM, when present, helps separate those possibilities.

Common questions

Does a drug test detect Morphine?

Yes. Morphine is one of the 76 compounds in the LabX LC-MS/MS confirmation panel, reported as detected at or above 50 ng/mL. The LabX 12-panel screen includes a Opiates line designed to pick up Morphine. A screen is presumptive; adding laboratory confirmation identifies Morphine specifically.

What is the laboratory cut-off for Morphine?

LabX reports Morphine as detected at or above 50 ng/mL, and the method's reportable range is 50–10,000 ng/mL. A result below the cut-off is reported as not detected; it does not prove none was present.

How long can Morphine be detected?

The laboratory lists an approximate window of 1-3 days, but it varies with dose, frequency of use, metabolism and hydration, and cannot be used to tell when something was taken.

Can a 12-panel drug screen detect Morphine?

The LabX 12-panel screen includes a Opiates line designed to pick up Morphine. A screen is presumptive; adding laboratory confirmation identifies Morphine specifically.

Is Morphine a prescription medicine?

Morphine is prescribed for moderate to severe pain, including pain after surgery and pain related to cancer, in short-acting and extended-release forms.
