Quick answer

Standard stack: MMR titer, varicella titer, hepatitis B titer (or vaccine series), Tdap, flu shot, plus TB screening. Titers prove IMMUNITY — vaccines alone rarely satisfy clinical contracts.

Who this covers

Why titers instead of vaccine records

Rotation contracts want laboratory PROOF of immunity. Childhood vaccines fade for a minority of people, and 'my mom says I had chickenpox' satisfies nobody's compliance office.

The core titer panel

  • MMR IgG — measles, mumps, rubella immunity in one draw
  • Varicella IgG — chickenpox immunity
  • Hepatitis B surface antibody (quantitative) — requires ≥10 mIU/mL; non-reactive results trigger a revaccination series then re-titer

Common extras

Tdap within 10 years, annual influenza, meningococcal for some programs, and occasionally hepatitis C antibody screening.

The hepatitis-B non-responder path

Roughly 5–10% of people don't seroconvert after the standard series. Programs handle it via repeat series ± higher-dose formulation, then documentation of antigen-negative status — budget time for this if your first titer comes back negative.

Order the required tests

Direct-access laboratory testing — no doctor visit needed. Results arrive as forwardable PDFs that satisfy most compliance offices.

Frequently asked questions

Can one blood draw cover everything?

Yes — MMR, varicella, and hep-B titers run off a single venipuncture. Ask the lab to batch them; it saves a needle and usually costs less than separate orders.

What if my titer shows no immunity?

Normal outcome — get the booster/vaccine series, wait the recommended interval (usually 4–8 weeks), re-titer. Start early enough to absorb this loop.
