Fentanyl Screen And Confirmation (Urine Test)

A fentanyl screen and confirmation test is a laboratory test that detects the presence of fentanyl in a person's urine. Fentanyl is a potent synthetic opioid that is commonly used as a pain reliever, but can also be misused as a recreational drug.

The screening test is usually done first, which is a quick and inexpensive test that can provide a preliminary result on whether fentanyl is present in the urine sample. If the screening test is positive, a confirmation test is usually done to confirm the presence of fentanyl and rule out any false positive results.

The confirmation test is more specific and accurate, often using techniques such as gas chromatography/mass spectrometry (GC/MS) or high-performance liquid chromatography (HPLC) to definitively confirm the presence of fentanyl in the urine sample.
