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.

False positive for valium

What can cause a false-positive urine getting pregnant while taking klonopin screening for benzodiazepines? First introduced in the s, benzodiazepines fall under the class of drugs referred to as sedative-hypnotics. It is not uncommon, however, for physicians to prescribe benzodiazepines along with opioids for patients with chronic pain.

When used in conjunction with opioid pain medications, benzodiazepines have been shown to enhance pain relief, but the combination can be accompanied by increased risks for abuse and accidental overdose. Given the increasing and widespread use of benzodiazepines, both alone and in conjunction with other medications, it is important for clinicians to use and understand urine drug screen UDS to fully manage patients.

UDS results can help optimize treatment by providing information about the presence of possibly illicit or non-prescribed drug use. However, clinicians need to be aware that false positive results can occur, necessitating confirmatory testing. What could cause a false-positive screen for benzodiazepines? A search of false positive benzodiazepine screenings showed the selective serotonin reuptake inhibitor SSRI sertraline "For valium," others and the effects of taking celebrex with tramadol 50mg high blood pressure anti-inflammatory drug NSAID oxaprozin Daypro, others to be associated with, or possible causes for valium, these false-positive results.

Although the mechanism is unknown, sertraline, which is used to treat depression, obsessive-compulsive disorder, panic disorder, and anxiety, has been shown to increase levels of benzodiazepines when used in combination. Nasky et taking clenbuterol and phentermine together performed a 2-year retrospective examination of records identifying patients with positive benzodiazepine screenings that GC-MS confirmed were falsely positive.

Sixty-two of the positive screens determined by positive false with the pharmacy database also had an active benzodiazepine prescription. In the remaining 98 patients without an active benzodiazepine prescription, 26 Most benzodiazepines undergo extensive metabolism in for valium liver, and there have been reports of cross reactivity to for valium metabolites. Typical detection windows for benzodiazepines in the urine are 2 to 7 days, depending on "valium" individual benzodiazepine drug used and other factors, such as time of last "for valium," drug half-life, route of administration, and individual differences in pharmacokinetics.

Nordiazepam and temazepam then are metabolized further to the final active metabolic product oxazepam. Thus, the presence of nordiazepam, temazepam, and oxazepam together on a UDS is consistent with diazepam use. One study compared valium for cross reactivity of oxaprozin with benzodiazepine assays using the fluorescence polarization immunoassay Abbott FPIAthe enzyme multiplied immunoassay technique Behring EMIT false positive. Twelve individuals participated and supplied urine at baseline, 24 hours, 48 hours, and 72 hours following a one-time dose of 1, mg of oxaprozin.

Baseline urine samples were available from 4 participants; all screened negative for benzodiazepines. Oxaprozin for valium was low 1. The results showed that 35 urine samples screened positive for benzodiazepines after 48 hours. The investigators used a GC-MS for valium confirmatory analysis. The study concluded that all positive for valium screenings should be confirmed by another analysis to rule valium potential false-positive results.

With conflicting evidence concerning the different benzodiazepine immunoassays, a study by Darragh et al, examined 3 different immunoassays specific for benzodiazepines to determine diagnostic accuracy. Out of urine screenings, were confirmed positive by LC-MS for 1 or more benzodiazepines. The highest sensitivities were found with samples for valium alpha-hydroxyalprazolam and the lowest sensitivities were found with samples containing lorazepam and 7-aminoclonazepam.

This study shows that even with a high sensitivity immunoassay such as the HS-CEDIA, there are still discrepancies that could lead to false reports if not confirmed. The use of urine drug analysis in patient care settings is useful for clinicians. Although tramadol 37.5 acetaminophen 325 dosage with oxaprozin is low, patients with a positive screening for benzodiazepines who also have an active prescription for oxaprozin or sertraline should have a confirmed GC-MS or LC-MS analysis.

It is not known whether sertraline or oxaprozin is a direct cause for false positive UDS, but the association cannot be ruled out. Benzodiazepine-positive screenings and any other positive screening results should be confirmed using another technique to rule out false positives that otherwise may compromise therapy.
