Frequently asked questions
How long does fentanyl stay in blood?
Detection time varies by dose, use pattern, and the person. Blood levels generally fall faster than urine levels, so timing matters.
What is the difference between the screen and confirmation?
The screen is a quick initial check. The confirmation is a more precise follow-up that reduces false positives.
Can prescribed fentanyl cause a positive result?
Yes. Prescribed fentanyl and some other medicines can produce a positive screen, which is why confirmation and clinical review are used.
Does a positive result mean I overdosed?
No. A positive result only shows that fentanyl was detected; a clinician must interpret what it means for your situation.
