In presence of smoke, the antibody can't color the antigen as cotinine prevents the antibody from coloring the antigen, and thus shows a positive outcome. The same principle applies for kits using urine, saliva and blood as samples.
Four kinds of these kits are available to detect presence of nicotine/cotinine in smokers. These include those using urine, saliva, blood and hair as test samples. Let us discuss each briefly.
