Short answer: If you can't find your vaccine records, a titer test proves your current immunity directly from a blood sample — no need to track down decades-old paperwork. If you're not sure which vaccines you're missing, ordering a combined panel like the Immunity Panel + TB is usually faster and cheaper than guessing at individual tests one at a time.

Quick answer

Titers measure your current immunity status, regardless of whether you were vaccinated or when. That makes them the standard workaround clinical and nursing programs accept when vaccination records are missing, incomplete, or simply can't be located.

What to order

• Check your childhood pediatrician's office and your state's immunization registry first — many records turn up faster than expected
• If records truly can't be found, order titers for whichever tests your program requires — usually MMR, Varicella, Hepatitis B, and a TB screen
• Not sure which ones you need, or missing more than one record? The Immunity Panel + TB bundles all four of the most commonly required tests into a single order and a single lab visit — simpler and less expensive than ordering each test separately
• If you only need to confirm one specific vaccine, an individual titer (linked below) is enough
• If a titer comes back non-immune, re-vaccination is the straightforward next step — there's no downside to a booster you may already have had

FAQ

Do I have to get every vaccine again if I can't find any records?

No — titers let you prove immunity to specific diseases individually, so you only need to address the ones where you're not already immune.

Will a titer be accepted even if my school wants vaccination dates?

Most nursing and clinical programs accept a current titer as an alternative to historical vaccination dates when records are unavailable, but confirm with your specific program's compliance office.

What's the easiest way to cover multiple missing records at once?

The Immunity Panel + TB combines the four titer/screening tests most schools require — Hepatitis B, MMR, Varicella, and TB — into one lab order, which is typically faster and less expensive than ordering each test individually.
