  • Nicotine and Cotinine, LC/MS/MS, Urine
  • NICOTINE U
  • LAB3979

Additional Technical Information

Ordering Recommendations

Recommended for determination of active or passive nicotine use or for differentiation between nicotine replacement and tobacco use. For a screening test to determine active exposure to nicotine and compliance with smoking-cessation programs, Cotinine Screen, Urine (2007081) is preferred.

Reference Interval

Effective August 17, 2015
Drugs CoveredCutoff Concentrations
Nicotine2 ng/mL
Cotinine (metabolite)5 ng/mL
3-OH-Cotinine (metabolite)50 ng/mL
Nornicotine (metabolite)2 ng/mL
Anabasine (tobacco biomarker)3 ng/mL

Interpretive Data

Methodology: Quantitative Liquid Chromatography-Tandem Mass Spectrometry

Positive cutoff:
Nicotine                2 ng/mL
Cotinine                5 ng/mL
3-OH-Cotinine          50 ng/mL
Nornicotine             2 ng/mL
Anabasine              3 ng/mL

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 drug 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.

Additional Technical Information

Ordering Recommendations

Confirm diagnosis of anti-NMDAR encephalitis. May be used in monitoring treatment response in individuals who are antibody positive.

Reference Interval

Effective May 21, 2012

Interpretive Data

Anti-NMDA receptor IgG antibody is found in a subset of patients with autoimmune limbic encephalitis and may occur with or without associated tumor. Decreasing antibody levels may be associated with therapeutic response; therefore, clinical correlation must be strongly considered. A negative test result does not rule out a diagnosis of autoimmune limbic encephalitis.
