A titer test measures the antibodies left behind by vaccination or past infection, and it is the standard way to prove immunity when records are missing or a program requires it: nursing and medical school enrollment, hospital and clinical employment, immigration medicals, international placements and some graduate programs. Each disease has its own titer, and schools usually name exactly which ones they accept.
Every titer is a standard blood draw at a Quest or Labcorp patient service center after a licensed physician reviews the order, with most results in 2–5 business days. The report states whether you are immune, non-immune or equivocal for each disease, and the lab’s own letterhead result is what the school or employer files.
| If you want to… | Order | Why |
|---|---|---|
| Proof of measles, mumps and rubella immunity for school or work | MMR Immunity Test (Measles, Mumps, Rubella)$289.99 · single test | All three MMR titers in one draw — the most commonly required set |
| Chickenpox immunity when you had the disease but have no record | Varicella Titer Test (Chickenpox Immunity IgG)$32.99 · single test | Varicella IgG; a positive is accepted in place of vaccination records by most programs |
| A program that asks for a quantitative (numeric) varicella titer | Quantitative Varicella IgG Titer (Numeric Result)$56.99 · single test | Reports the antibody level, not just positive or negative, where the form requires it |
| Hepatitis B immunity after the vaccine series, or for healthcare employment | Hepatitis B Immunity Test$27.99 · single test | Hepatitis B surface antibody; a level of 10 mIU/mL or more is accepted as protective |
| The three titers nursing and medical programs ask for, in one order | Immunity Check Panel$329.99 · 3 tests | MMR, varicella and hepatitis B surface antibody together; add the TB blood test to complete the usual school list |
| Proof you do not have TB for employment, school or housing | Tuberculosis (TB) Blood Test$91.99 · single test | The IGRA blood test replaces the two-visit skin test and is not affected by BCG vaccination |
| The blood tests an immigration medical requires | Immigration Exam Prep Panel$159.99 · 3 tests | TB blood test plus syphilis and gonorrhea/chlamydia screening — the civil surgeon’s list; titers are added only if vaccination records are missing |
| A quick measles-only check during an outbreak or for travel | Measles Immunity Test$129.99 · single test | Measles IgG alone when the other titers are already on file |
Both routes satisfy most requirements, and the choice is practical. A titer confirms immunity in one visit and avoids unnecessary doses if you were vaccinated as a child but cannot find the card; it also documents natural immunity after chickenpox or measles. Revaccination skips the test but takes two or three visits over weeks to months for MMR and hepatitis B and can delay a start date. A negative or equivocal titer is not a failed test — it is the result that tells you a booster is needed, and most programs accept the booster record afterward without a second titer, except for hepatitis B, where a post-vaccination titer is often required to document response.
Nursing, medical, dental, physician-assistant and allied-health programs almost always require measles, mumps and rubella, varicella and hepatitis B — the Immunity Check Panel — plus a TB test. Hospital employment mirrors that list. Immigration medicals are set by the civil surgeon: the required blood work is TB, syphilis and gonorrhea/chlamydia screening, with MMR and varicella titers added only where vaccination records are missing. Study-abroad and volunteer placements vary; a quick measles titer is the common ask during outbreaks. Read the exact wording of your form before ordering: some require a quantitative varicella titer, and some will not accept a titer for a disease where only the vaccine record is listed.
Each titer returns a value and an interpretation: immune (protective antibody present), non-immune (none detected) or equivocal (borderline). For hepatitis B the protective threshold is a surface antibody of 10 mIU/mL or more; for the others the lab applies its own cut-off and states it on the report. Antibody levels fall over time, so a childhood vaccination can produce a non-immune result decades later even though some protection may remain; programs treat the report literally, and a booster resolves it. An equivocal result is usually repeated or boosted. The TB blood test is different: it detects infection, not immunity, so a negative is the desired result, and a positive needs clinical follow-up to separate latent infection from disease.
A blood test that measures the antibodies produced by vaccination or past infection. It proves immunity to a specific disease — measles, mumps, rubella, varicella, hepatitis B and others — for school, work and immigration requirements when records are missing.
Almost always measles, mumps and rubella, varicella (chickenpox) and hepatitis B surface antibody, plus a TB test. The Immunity Check Panel covers the three titers in one draw and the TB blood test is added to the same order; check your program’s form for a quantitative varicella requirement.
Most titers return in 2–5 business days; the TB blood test in 2–4. Order a week or two before a deadline to allow for a booster if a result comes back non-immune.
A negative or equivocal result means a booster is recommended; programs accept the booster record afterward. For hepatitis B, a follow-up titer one to two months after the booster documents that you responded.
No — titers measure protective antibodies, not active infection, with one exception: the TB blood test detects TB infection, so for TB a negative is the result you want.
Yes. Order online, a licensed physician reviews the requisition, and you have blood drawn at a nearby Quest or Labcorp. The lab report in your portal is the document schools and employers file.
