Titer - Wikipedia

Titer (American English) or titre (British English) is a way of expressing concentration. Titer testing employs serial dilution to obtain approximate quantitative information from an analytical procedure that inherently only evaluates as positive or negative. The titre corresponds to the highest dilution factor that still yields a positive reading. For example, positive readings in the first 8 serial, twofold dilutions translate into a titer of 1:256 (i.e., 2 ). Titres are sometimes expressed by the denominat… Antibodies, or immunoglobulins, are specialized proteins produced by the immune system to identify and destroy foreign invaders, such as bacteria and viruses. An antibody titer blood test is done to determine the presence (qualitative) and amount (quantitative) of antibodies in the blood.
