Enterprise HealthTiter
A blood test that measures antibody levels to confirm immunity to a disease, often accepted in place of revaccination.
Key facts
- Blood test measuring antibody levels to confirm immunity.
- Accepted in place of records for MMR, varicella, HepB and more.
- Insufficient levels trigger boosters.
What it means
A titer quantifies antibodies — for measles, mumps, rubella, varicella or hepatitis B — to document existing immunity. Health systems and universities accept titers as proof of immunity when vaccination records are missing, so results must be captured against immunization requirements and trigger boosters when levels are insufficient.
Frequently asked
What is a titer used for?
To quantify antibodies and document existing immunity — for measles, mumps, rubella, varicella or hepatitis B. It's often accepted when vaccination records are missing.
What if a titer shows low immunity?
An insufficient titer typically triggers a booster or revaccination. Results are captured against immunization requirements so the gap is closed and tracked.
