Antibody titers refer to the concentration of specific antibodies present in the blood, indicating the strength of an immune response to a particular antigen. Measuring antibody titers is crucial for assessing immunity levels, vaccine efficacy, and diagnosing infections or autoimmune conditions.

Assessing immunity levels

Vaccine efficacy measures the percentage reduction of disease in a vaccinated group compared to an unvaccinated group under optimal conditions, indicating how well a vaccine works in controlled clinical trials. It is a critical metric for understanding a vaccine's potential impact on public health and guiding immunization strategies.

Diagnosing Infections

Autoimmune conditions occur when the immune system mistakenly attacks the body's own healthy cells, perceiving them as threats. These disorders can affect any part of the body, leading to chronic inflammation and tissue damage, and often require lifelong management to control symptoms and prevent complications.
