Drug Monitoring Panel 1 with Confirmation Urine

Laboratory
Quest Diagnostics
Test code
39422
Specimen
Urine
Fasting
Not stated as required

What the laboratory says this test is for

The test is a screening assay using a homogeneous enzyme immunoassay method of analysis. Presumptive positive screen results are reflexed to a more specific and sensitive liquid chromatography mass spectroscopy (LC/MS/MS) test. Therapeutic urine drug monitoring is important for ensuring compliance to treatment strategies, as well as ensuring non-diversion for illicit purposes. Urine or oral fluid are the specimens of choice for routine monitoring of patients taking prescription drugs. Use of serum/plasma should be limited to anuretic patients, or where a patient's clinical appearance does not coincide with their prescribed medications. No single monitoring approach provides adequate information about the pattern or dose of patient drug use. Safest prescribing habits should include a combination of tools and laboratory test results to correctly detect drug use patterns. Urine drug test results equal to or greater than cutoff are reported as positive and results less than cutoff are reported as negative. Quantitative values cannot be used to assess the drug dose, because the drug is extensively metabolized and excreted in the urine.

Drug Monitoring Benzodiazepines with Confirmation Urine

Laboratory
Quest Diagnostics
Test code
39371
Specimen
Urine
Fasting
Not stated as required

What the laboratory says this test is for

The benzodiazepine class of drugs are traditionally classified as depressants. They are used therapeutically to produce sedation, induce sleep, relieve anxiety, treat muscle spasms, and to prevent seizures. In general, benzodiazepines act as hypnotics in high doses, anxiolytics in moderate doses, and sedatives in low doses. The test is a screening assay using a homogeneous enzyme immunoassay method of analysis. Presumptive positive screen results are reflexed to a more specific and sensitive liquid chromatography mass spectroscopy (LC/MS/MS) methodology. Therapeutic urine drug monitoring of the benzodiazepines is important for ensuring compliance to treatment strategies, as well as ensuring non-diversion for illicit purposes. Urine or oral fluid are the specimens of choice for routine monitoring of patients taking prescription drugs. Use of serum/plasma should be limited to anuretic patients, or where a patient's clinical appearance does not coincide with their prescribed medications. No single monitoring approach provides adequate information about the pattern or dose of patient drug use. Safest prescribing habits should include a combination of tools and laboratory test results to correctly detect drug use patterns. Urine drug test results equal to or greater than cutoff are reported as positive and results less than cutoff are reported as negative. Quantitative values cannot be used to assess the drug dose, because the drug is extensively metabolized and excreted in the urine.

Chlordiazepoxide and Metabolites

Laboratory
Quest Diagnostics
Test code
91123
Specimen
Serum
Fasting
Not stated as required

What the laboratory says this test is for

This definitive drug assay is used to measure concentrations of chlordiazepoxide, norchlordiazepoxide, and nordiazepam in serum. This therapeutic drug monitoring assay may be used to assess if chlordiazepoxide and metabolites are within therapeutic range. Urine and oral fluid are the specimens of choice for routine monitoring of patients taking prescription drugs.Chlordiazepoxide is a long-acting benzodiazepine used to treat adults for anxiety disorder, preoperative apprehension and anxiety, and withdrawal symptoms of acute alcohol use disorder. It is also used to treat children older than 6 years for anxiety.Chlordiazepoxide has several active metabolites, and prolonged duration of action may lead to serious adverse effects in older individuals, children, and individuals with disabilities or hepatic or renal impairment. Common adverse effects include drowsiness, fatigue, dizziness, ataxia, forgetfulness, slurred speech, irritability, and rash. Chlordiazepoxide intoxication and overdose can be life-threatening, especially when chlordiazepoxide is combined with alcohol and other central nervous system depressants [1,2]. However, routine quantitative tests of chlordiazepoxide are not needed unless medical conditions warrant monitoring or for individuals taking other drugs that increase the risk of intoxication [2].The results of this test should be interpreted in the context of pertinent clinical history and physical examination findings.References1.

What the laboratory says this test is for

Benzodiazepines are widely used as anxiolytics, sedative- hypnotics, muscle relaxants, and anticonvulsants. Benzodiazepines include drugs such as diazepam Valium®, chlordiazepoxide Librium®, oxazepam Serax®, lorazepam Ativan®, alprazolam Xanax®, clonazepam Clonopin® and triazolam Halcion®. Many common benzodiazepines are detected in urine by their metabolites oxazepam and nordiazepam. Psychological and physiological addictions, misuse and abuse of benzodiazepines have been described.
