Urine drug screening is a common way to test for compliance with medications having high abuse potential. False-negatives and false-positives from immunoassays can lead to adverse consequences for patients and providers. By identifying medications that contribute to false-negatives and false-positives, pharmacists decrease misinterpretations from urine drug screens. Unexpected results from urine immunoassays should have a confirmatory gas chromatography—mass spectrometry or a high-performance liquid chromatography test performed.

Hydrolysis of urine before benzodiazepine immunoassay screening and optimization of the immunoassay absorbance cutoff were found to improve the rate of false-negative screening in a study published in the Journal of Applied Laboratory Medicine. After selecting an optimized absorbance cutoff for immunoassays 20 vs , a prospective trial of all urine samples was performed. Hydrolysis had no effect on truly negative samples, but did increase the absorbance levels of 7 of 17 true-positive urine samples containing lorazepam, diazepam, or alprazolam. Hydrolysis had no effect on urine samples containing clonazepam or 7-aminoclonazepam. Improved clinical sensitivity of a reflexive algorithm to minimize false-negative test results by a urine benzodiazepine immunoassay screen. J Appl Lab Med. Patients with multiple sclerosis-related chronic pain were found to have spectral abnormalities within the dynamic pain connectome regions.

Benzodiazepines, which first entered the US pharmaceutical market in the early s, fall under the class of drugs referred to as sedative-hypnotics.
