Siemens Healthineers, Erlangen, Germany, is now distributing the Ark fentanyl assay from Ark Diagnostics, Fremont, Calif. The assay will provide laboratories with a greater window to screen for fentanyl to more effectively triage patients who have been exposed to this opioid.

The Centers for Disease Control and Prevention describes fentanyl as a synthetic opioid that is 50 times more potent than heroin and 100 times more potent than morphine. There are two types of fentanyl. Pharmaceutical fentanyl is prescribed to manage severe pain in cancer and surgical patients and to provides end-of-life palliative care. Nonpharmaceutical fentanyl, or illicitly manufactured fentanyl, is often mixed with heroin or cocaine—with or without the user’s knowledge. Addictive cocktails incorporating illicitly manufactured fentanyl have created the leading cause of drug overdose death.

Both the potency of fentanyl and the alarming rise in misuse and abuse poses an overdose danger, thereby increasing the need for effective diagnostic tests that can confirm the presence of fentanyl. Fentanyl can be absorbed into the body several different ways, and it poses a risk to anyone, including first responders and healthcare personnel, who come into contact with the drug.4

The Ark fentanyl assay extends the detection window to provide the information clinicians need to triage patients more appropriately. This is important because fentanyl absorption occurs at different rates depending upon the type of exposure, and during this time a patient will typically face suppressed respiratory function and should be closely monitored. When consumed, fentanyl is metabolized to norfentanyl and other metabolites. About 90% of the dose is excreted in urine as norfentanyl, while parent fentanyl accounts for less than 7%. Because fentanyl metabolizes quickly, assays measuring solely the parent fentanyl typically have a shorter window for detection. The Ark fentanyl assay can detect both norfentanyl and the parent fentanyl, enabling laboratories to identify more true positives.

Identifying more true positives also supports patients seeking addiction treatment. Many healthcare facilities do not currently have fentanyl testing on their assay menu, which is hindering patients’ ability to seek detox support. Insurance providers often require a positive drug test to cover treatment costs or patients can be denied admission completely.

“Fentanyl testing provides necessary clinical information for more effective patient care where a gap currently exists. Adding the Ark fentanyl assay to the Atellica solution menu offers laboratories an extensive drugs-of-abuse testing menu which can be run efficiently on a single instrument,” says Deepak Nath, PhD, president of laboratory diagnostics for Siemens Healthineers. “It also empowers laboratories to help identify exposure and addiction in their communities, and aids clinicians in getting patients on the path to treatment.”

The Ark fentanyl assay is FDA cleared and CE marked. It is available on automated clinical chemistry analyzers offered by Siemens Healthineers, including the Atellica solution, as well as Dimension, Dimension Vista, and Viva systems. Using the Ark fentanyl assay, opioid testing can be consolidated with other Siemens Healthineers assays, including 6-Acetylmorphine, buprenorphine, methadone, opiates, and oxycodone.
