Drug Screen by Immunoassay, Urine

Test Overview

Test Methodology

Kinetic Immunoassay (KIMS)

Test Usage

Detection of abused drugs: amphetamines, barbiturates, benzodiazepines, cannabinoids, cocaine metabolites, opiates, and oxycodone.

Reference Range*

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.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

1. Due to structural differences FENTANYL is not detected by the Opiate assay. Please contact MLabs for requests to analyze for this drug. 2. Rifampin can cause 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 can have a false positive amphetamine screen due to a metabolite of labetalol having structural similarity to amphetamine. 5. Lorazepam is not detected by the Benzodiazepine immunoassay screen. 6. If the drug screen failed to report a specific drug of interest, please contact MLabs for additional help. 7. Positive results by immunoassay should be considered presumptive. Confirmation by an alternate method may be requested by contacting MLabs.
