Acetyl fentanyl overdose deaths have recently been confirmed in Pennsylvania. If states observe clusters or increases in illicit opioid-related overdoses above expected levels, acetyl fentanyl could be involved. CDC encourages laboratories to use an ELISA test to screen specimens from suspected illicit, nonpharmaceutical opioid overdose deaths. If an ELISA test is positive for fentanyl, CDC recommends confirmatory testing by GCMS.
