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 certain infectious diseases. Rather than simply recording a positive or negative result, a titer quantifies antibody levels, which can indicate whether prior vaccination or past infection has produced a measurable immune response.
About Immunity Detection & Titer Testing in Romeoville
Titer testing is used to assess immune status for diseases such as measles, mumps, rubella, varicella, hepatitis B, and others, depending on the panel ordered.
A titer test works by diluting a blood sample in a series of steps and adding a known quantity of antigen. The highest dilution at which antibodies are still detectable is reported as the titer, often expressed as a ratio such as 1:40 or 1:80. Higher titers generally reflect greater antibody concentration.
Results are interpreted against reference thresholds that vary by disease and by the purpose of testing. A result at or above the threshold is typically considered evidence of immunity, while a result below it may suggest susceptibility and the possible need for vaccination or a booster. Some assays also distinguish between IgG and IgM antibodies to help differentiate past exposure or vaccination from recent infection.
The panel may include one or several targets depending on the clinical or administrative reason for testing. Common settings include pre-employment or school health requirements, healthcare worker screening, and confirmation of immunity before immunosuppressive treatment. Because antibody levels can wane over time, a titer below the threshold does not necessarily mean the immune system has no memory of the pathogen; it means circulating antibodies are below the level the assay recognizes as protective.
