Barbiturates Quantitative Confirmation Serum

Laboratory
Quest Diagnostics
Test code
7377
Specimen
Serum
Fasting
Not stated as required

What the laboratory says this test is for

This definitive drug assay is used to confirm presumptive positive results and identify the specific barbiturates in serum. Urine and 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.Barbiturates are a group of central nervous system (CNS) depressants that are used as sedatives, hypnotics, anesthetics, and anticonvulsants. Because barbiturates have a low therapeutic index and high abuse potential, they have been largely replaced by benzodiazepines for sedative and hypnotic purposes. Measurement of barbiturates in serum is helpful in the diagnosis and management of barbiturate intoxication as well as monitoring therapy [1]. Immunoassays are usually used to screen for barbiturate intoxication; positive screening results can then be confirmed with quantitative chromatography/mass spectrometry testing [1,2].The results of this test should be interpreted in the context of pertinent clinical history and physical examination findings.References1.

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.
