The fentanyl urine test cassette is a rapid urine screening test that can be performed without the use of an instrument. The test utilizes a monoclonal antibody to selectively detect elevated levels of Fentanyl in urine. The fentanyl urine test cassette yields a positive result when fentanyl in urine exceeds 1 ng/ml.
- Ultra-high sensitivity detects fentanyl down to low levels of 1 ng/ml
- For in vitro diagnostic use
- Accurate results in 5 minutes
The fentanyl urine test cassette is an immunoassay based on the principle of competitive binding. Drugs which may be present in the urine specimen compete against the drug conjugate for binding sites on the antibody. During testing, a urine specimen migrates upward by capillary action. Fentanyl, if present in the urine specimen below 1 ng/ml, will not saturate the binding sites of antibody-coated particles in the test device. The antibody-coated particles will then be captured by immobilized FYL conjugate and a visible colored line will show up in the test line region. The colored line will not form in the test line region if the FYL level exceeds 1 ng/ml because it will saturate all the binding sites of anti-FYL antibodies. A drug-positive urine specimen will not generate a colored line in the test line region, while a drug-negative urine specimen or a specimen containing a drug concentration less than the cut-off will generate a line in the test line region. To serve as a procedural control, a colored line will always appear at the control line region indicating that proper volume of specimen has been added and membrane wicking has occurred.
