Order Code:LAB1152Order Name:Nicotine and Mets, Urn, Quant
Methodology:Quantitative liquid chromatography/Tandem mass spectrometry
CPT Codes: 80323 x1, 80323 x1
Turnaround Time:Specimens are sent to the reference laboratory Sun-Sat; results are reported within 1-4 days.
Compliance:

This test uses a manufacturer labeled Analyte Specific Reagent (ASR) as the reagent providing the specificity of the assay. The test was developed and its performance characteristics determined by ARUP Laboratories. It has not been cleared or approved by the US Food and Drug Administration. This test was performed in a CLIA certified laboratory and is intended for clinical purposes.

Interpretive

Reference Range:
Drugs Covered Positive Cutoff
Concentrations
Nicotine 15 ng/mL
Cotinine (metabolite) 15 ng/mL
3-OH-Cotinine (metabolite) 50 ng/mL
Anabasine (tobacco biomarker) 5 ng/mL
 
Use:For medical purposes only; not valid for forensic use.

This test is designed to evaluate recent use of nicotine-containing products. Passive and active exposure cannot be discriminated definitively, although a cutoff of 100 ng/mL cotinine is frequently used for surgery qualification purposes. For smoking cessation programs or compliance testing, the absence of expected drug(s) and/or metabolite(s) may indicate non-compliance, inappropriate timing of specimen collection relative to drug administration, poor drug absorption, diluted/adulterated urine, or limitations of testing. The concentration value must be greater than or equal to the cutoff to be reported as positive. Anabasine is included as a biomarker of tobacco use, versus nicotine replacement. Interpretive questions should be directed to the laboratory.
