CONTININE(QUANTITATIVE METHOD) – SERUM

This test is a blood test used to measure the exact concentration of cotinine, a metabolite of nicotine. Since cotinine remains in the body longer than nicotine, it is a reliable indicator of recent tobacco or nicotine exposure.

The purpose of this test is to:

• Measure exact cotinine levels in the blood
• Assess recent nicotine or tobacco exposure
• Differentiate active smoking from passive exposure
• Monitor progress in smoking cessation programs
• Support clinical and workplace screening

CONTININE(QUANTITATIVE METHOD) – SERUM Test Purpose

The Serum Cotinine (Quantitative Method) Test measures the exact concentration of cotinine, the primary metabolite of nicotine, in the blood. Since cotinine remains in the body much longer than nicotine, it serves as a reliable biomarker for detecting recent tobacco and nicotine exposure. Unlike qualitative tests that simply indicate the presence or absence of cotinine, this quantitative test provides precise cotinine levels, helping healthcare providers assess the extent of nicotine exposure.

The test is commonly used to confirm active smoking, vaping, or the use of other nicotine-containing products such as chewing tobacco, nicotine gums, patches, and lozenges. It is also valuable for monitoring individuals enrolled in smoking cessation programs, evaluating exposure to secondhand smoke, and verifying tobacco-free status for pre-employment screening, insurance assessments, organ transplantation, or certain surgical procedures. Healthcare providers may use the results to guide smoking cessation counseling, monitor treatment progress, and assess overall nicotine exposure.

CONTININE(QUANTITATIVE METHOD) – SERUM TEST is Recommended for Individuals:

• Individuals enrolled in smoking or tobacco cessation programs.
• People who want to confirm successful smoking or vaping cessation.
• Users of cigarettes, e-cigarettes, chewing tobacco, or other nicotine-containing products.
• Individuals with suspected exposure to secondhand smoke.
• Patients undergoing pre-employment, insurance, transplant, or pre-operative evaluations requiring nicotine screening.
• Healthcare providers monitoring nicotine replacement therapy.
• Anyone advised by a healthcare provider to assess recent nicotine exposure.

FAQs

1. What is the Serum Cotinine (Quantitative Method) Test used for?
This test measures the exact level of cotinine in the blood to detect and quantify recent nicotine exposure. It helps confirm tobacco use, monitor smoking cessation, and evaluate secondhand smoke exposure.

2. Do I need to fast before the Serum Cotinine Test?
No. Fasting is generally not required before a Serum Cotinine (Quantitative Method) Test. However, follow any specific instructions provided by your healthcare provider or diagnostic laboratory.

3. How long can cotinine be detected in the blood?
Cotinine is typically detectable in the blood for 2–4 days after nicotine use, although it may remain detectable for a longer period in heavy tobacco users or individuals with frequent nicotine exposure.
