The more a sample can be diluted and yet still react with antigen, the higher the concentration of antibodies in that sample and the higher is its titer.
Antibodies, also called immunoglobulins (Ig), are proteins responsible for warning the body when there is a disease-causing agent (such as bacteria, viruses, among others) in the body. They act to eliminate it, and in the process, other cells will be activated to help with this task.
Titration is a laboratory procedure used to determine the concentration in amount of matter (titer) of a solution that contains an acid or a base. During the titration, there is always a mixture of solutions containing different solutes with chemical reaction occurring.
