Systems and methods for distinguishing cotinine from anabasine in a point-of-care testing device
A system for determining a level of Cotinine and Anabasine in a sample includes a test strip configured to receive a sample; and a meter configured to receive the test strip wherein the meter is configured to read the test strip and detect a level of Anabasine and Cotinine.
1. A system for determining a level of nicotine metabolites, in a sample, comprising:
a test strip configured to receive a sample; and
an analyzer configured to receive the test strip wherein the analyzer is configured to read the test strip and detect a level of a first nicotine metabolite and a second nicotine metabolite; wherein the first nicotine metabolite is Anabasine and the second nicotine metabolite is Cotinine, the test strip includes an Ab-particle Conjugate Stripe, the Ab-particle Conjugate Stripe including Ab-particle Conjugates for binding with one of Anabasine and Cotinine, the test strip includes an Ab-particle Conjugate Stripe, the Ab-particle Conjugate Stripe including microparticles combined with a Cotinine antibody and microparticles combined with an Anabasine antibody, the test strip include a first test site and a second test site, the first test site including compounds to bind with the microparticles combined with a Cotinine antibody, and the second test site including microparticles combined with an Anabasine antibody.
2. The system of claim 1 , wherein the analyzer is configured and executing code to determine whether the sample is from an individual who consumed tobacco products or an individual who consumed cessation products based on the level of the first nicotine metabolite and the level of the second nicotine metabolite.
3. The system of claim 1 , wherein the microparticles are fluorescent.
4. The system of claim 1 , wherein the microparticles have reflective properties.
5. The system of claim 1 , wherein the microparticles have properties that provide for the absorption of light.
6. The system of claim 3 , wherein the analyzer measures a level of absorption at the first test site to determine the level of Cotinine, and the analyzer measures a level of absorption at the second test site to determine the level of Anabasine.
7. The system of claim 4 , wherein the analyzer measures a level of reflection at the first test site to determine the level of Cotinine, and the analyzer measures a level of reflection at the second test site to determine the level of Anabasine.
8. The system of claim 5 , wherein the analyzer measures a level of fluorescence at the first test site to determine the level of Cotinine, and the analyzer measures a level of fluorescence at the second test site to determine the level of Anabasine.
9. The system of claim 1 , wherein the sample is blood.
