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 recording a positive or negative result, a titer quantifies how much antibody is present, which can clarify whether prior vaccination or past infection has produced a durable immune response.
About Immunity Detection & Titer Testing in Philadelphia
Titer testing translates antibody levels into actionable information about immune status.
A titer is a laboratory measurement of antibody concentration, typically reported as a ratio such as 1:8 or 1:64. Higher ratios indicate greater antibody presence. The immune system produces these proteins in response to either vaccination or natural infection, and their persistence varies by pathogen, vaccine type, and individual factors such as age or immune status.
Different diseases require different thresholds to be considered protective. For example, antibody levels against measles, mumps, rubella, hepatitis B, and varicella are each interpreted against pathogen-specific cutoffs. Some tests also distinguish between IgG and IgM antibodies: IgG generally reflects longer-term immunity, while IgM often indicates a more recent or active infection.
Clinicians use titer results to guide decisions about re-vaccination, to verify immunity before certain exposures or treatments, and to document immune status when vaccination records are unavailable. A result below the protective threshold does not necessarily mean a person is vulnerable, and a result above it does not guarantee complete protection, so interpretation should always occur in clinical context.
