Abstract
A system for determining a concentration of hemoglobin A1C includes a first lateral flow test strip, the first lateral flow test strip providing for a percent of HbA1C concentration; a second lateral flow test strip, the second lateral flow test strip providing for the total amount of hemoglobin; an antibody-microparticle stripe on each of the first and second lateral flow test strips; a conjugate stripe on each of the first and second lateral flow test strips; and a sample treatment buffer. The sample treatment buffer is strongly denaturing, and antibodies in the antibody-microparticle strip are covalently bound to microparticles.
