Rapid Determination of Sufentanil in Human Plasma by UHPLC–QqQ-MS-MS

Efavirenz (EFV) (6), used for the treatment of HIV, has been shown to cross-react with Biosite Triage 8 ® kit for benzodiazepines . The authors created a blinded study in which half of the patients (n = 50) were therapeutically dosed with EFV and the other half (n = 50) were not.

These false-positive results support the generally accepted practice that immunoassay positive results are considered presumptive until confirmed by a second independent chemical technique.Immunoassays dominate urine drug screens (UDSs) because they are simple to use, easy to automate and provide rapid results (Because many providers have limited knowledge of immunoassay cross-reactivity data, patients with false-positive results may lose eligibility in rehabilitation programs, be inappropriately terminated from employment or suffer from medical staff bias because of lack of trust (This review focuses on cases where the cause of a false positive is identified.

While it is useful to understand some of the common causes of false-positive immunoassay results, in the majority of cases the cause of false-positive screening results is unknown. Diseases & Conditions Efavirenz belongs to a class of drugs known as non-nucleoside reverse transcriptase inhibitors (NNRTIs).

Many cross-reactivities exist with other analytes, potentially causing a false-positive result in an initial drug screen.

Immunoassays provide useful clinical information, but should be viewed as ‘presumptive positive’ results until confirmed by an independent chemical technique such as GC–MS or liquid chromatography–tandem mass spectrometry.The authors acknowledge the generous funding provided by Waters Corporation for the University of California, San Diego (UCSD) clinical chemistry fellowship program.

Simply adding the parent drug to DFU and demonstrating the absence of a positive result does not rule out ingestion of a particular drug as the cause of a false-positive result.

PO: May be administered without regard to meals. These articles were then analyzed to determine if they included data on false-positive urine immunoassay results.
