Question Answer
Urine drug testing (UDT) is an effective means of doing what?monitoring patients for substance abuse or misuse
What can UDT determine?1) if a patient is taking drugs (legal or illicit) that they should be taking 2) if a patient is taking a prescribed controlled substance rather than diverting it
UDT is an important aid when prescribing what?chronic opioid medications
List the ways that UDT can be performed?1) point of service (POS) immunoassay testing 2) lab based testing utilizing gas chromotographic/mass spectroscopy, high performance liquid chromatography or liquid chromatography tandem mass spectroscopy
What is the POS (point of service) UDT based on?competitive binding and the use of antibodies to detect specific chemical structures
Panels of immunoassay tests are available to identify a large number of prescirption and illicit drugs and their metabolites, true or false?true
Tests are designed to identfy a specific substance ________, resulting in either a positive color change or a negative color change?threshold
When ordering a UDT, it is important to know what?what drugs that specific assay or panel tests for
The "Federal Five" opiate assays test only for what two drugs?codeine and morphine
An expanded panel tests for what drugs?fentanyl (Duragesic), meperidine (Demerol), semisynthetic (oxycodone (Oxycontin), hydrocodone, methadone) opioids
List the advantages of using the immunoassay POS urine drug testing?1) rapid results at the time of patient care 2) lower cost than lab-based testing 3) ease of testing 4) CLIA-waved status
Why do false positives occur in POS urine drug testing?because the test is based on an antibody identification of a chemical structure, false positives can occur due to presence of similar chemical compounds
Give one example where there is a false positive for metgadone?Quetiapine (Seroquel) can cause a false-positive result for Methadone
How can false negatives occur in POS urine drug testing?as a result of urine concentrations not meeting the pre-determined drug threshold
*** In cases, where false-positive or false negative results are possible, what is needed to confirm results? Can POS urine drug testing quantify a particular urine drug concentration?1) further lab-based testing may be necessary 2) no (only lab-based testing can)
POS urine drug testing can detect methadone intake for ____ to ____ days AFTER the final dose?2; 4
Providers must recognize that urine drug testing may test for active drugs and their metabolites, give one example?a patient on codeine may test positive for morphine (which is a metabolite of codeine)
Negative results on POS testing may indicate that the patient does NOT meet a pre-determined drug threshold level and does not necessarily indicate what?drug diversion
*** SUMMARY = UDT (urine drug testing) is an effective means of monitoring patients for what?substance abuse or misuse
*** SUMMARY = Whenever ordering a UDT, it is extremely important to know what?what drugs that specific assay or panel tests for
*** SUMMARY = UDT may test for active drugs and their metabolites, true or false?true
