Negative Threshold cut off levels: Amphetamines 1000 ng/mL; Barbiturates 200 ng/mL; Benzodiazepines 100 ng/mL; Cannabinoids 50 ng/mL; Cocaine metabolites 300 ng/mL; Opiates 300 ng/mL; Oxycodone 100 ng/mL; Fentanyl 1 ng/mL. Creatinine >20 mg/dL
Test Usage:
Detection of abused drugs: amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine metabolites, opiates, oxycodone, and fentanyl. Creatinine for specimen adulteration.
Test Limitations:
1. Positive results by immunoassay should be considered presumptive. Confirmation by an alternate method may be requested by contacting the laboratory. 2. Rifampin can cause a false positive urine opiate screen. 3. The presence of hydrocodone in a urine sample can cause a false positive urine oxycodone screen. 4. Patients on Labetalol, Ranitidine (Zantac), Trimethobenzamide or Trazodone can have a false positive amphetamine screen due to metabolites of these drugs having structural similarity to amphetamine. 5. If the drug screen failed to report a specific drug of interest, please contact the laboratory for additional help.
Test Methodology:
Kinetic Immunoassay (KIMS)
Additional Information:
Includes Detection of abused drugs: amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine metabolites, opiates, oxycodone, and fentanyl. In addition, creatinine value for specimen adulteration. Each of the drugs may be ordered individually. Confirmation of positive results by an alternative method may be requested by contacting the MLabs Cline Services Center.
