Order Immunity Detection & Titer TestingImmunity detection and titer testing measures the concentration of specific antibodies in the blood to determine whether a person has protective immunity against a particular infectious disease. Rather than simply reporting a positive or negative result, a titer quantifies antibody levels, which can clarify whether prior infection or vaccination has produced a measurable immune response.
About Immunity Detection & Titer Testing in Philadelphia
Titer testing translates antibody concentrations into actionable information about immune status.
A titer test works by diluting a blood sample repeatedly and adding a known quantity of antigen. The highest dilution at which antibodies still bind and produce a detectable reaction is reported as the titer, often expressed as a ratio such as 1:40 or 1:80. A higher ratio indicates a greater concentration of specific antibodies.
Titers are commonly used for diseases such as measles, mumps, rubella, varicella, hepatitis B, and hepatitis A. For some conditions, a result above a defined threshold is accepted as evidence of immunity, while a result below that threshold may suggest susceptibility and the possible need for revaccination. Interpretation depends on the specific disease, the laboratory method, and the individual's health history.
Because antibody levels can decline over time, a titer reflects immune status at the moment of collection rather than a permanent guarantee of protection. Results should be reviewed alongside vaccination records and clinical context, and they do not replace a medical evaluation when symptoms or exposure concerns are present.
