# Back-to-School Lab Tests: TB, Titers, and Health-Form Requirements Without the Runaround

*College and school health forms due before enrollment? Here's what TB tests and immunity titers schools actually accept, and how to clear the requirements in days — no doctor's visit needed.*

> Most US schools and colleges require two things on the health form: proof of tuberculosis screening and proof of immunity to measles, mumps, rubella, varicella, and hepatitis B. Both are blood tests you can order online and have drawn at Quest or Labcorp: the one-visit QuantiFERON TB test ($91.99), unaffected by childhood BCG vaccination, and IgG titers when vaccination records are lost. Results in 2–5 business days as an uploadable PDF.

## Recommended tests

| Recommended | Type | Price | Why |
| --- | --- | --- | --- |
| [Tuberculosis (TB) Blood Test](https://www.test-well.com/tests/tuberculosis-blood-test) | Test | $91.99 | The TB test schools accept — one visit, BCG-proof — $91.99 |
| [MMR Immunity Test (Measles, Mumps, Rubella)](https://www.test-well.com/tests/mmr-immunity-test) | Test | $289.99 | Prove measles/mumps/rubella immunity without records |

| [Hepatitis B Immunity Test](https://www.test-well.com/tests/hepatitis-b-immunity) | Test | $31.99 | Quantitative anti-HBs — the 10 mIU/mL proof — $31.99 |

All prices are cash-pay plus one $6 lab processing fee per order; physician authorization is included.

## The August Scramble

It's the same every year. Health forms are due before enrollment, the campus health portal wants TB screening documentation and proof of immunity, and the pediatrician or clinic is booked out for weeks. For international and health-science students there's a hard **health hold** on registration until the documentation is uploaded.

The good news: essentially every lab requirement on a school health form is a blood test you can order online today — no doctor's appointment, no referral — get drawn at a Quest or Labcorp near campus or home, and upload the PDF result 2-5 business days later. This guide covers exactly what schools ask for, which specific tests they accept, and how to sequence them against a deadline.

## TB Screening: The Test Schools Accept

Tuberculosis screening is the near-universal requirement, and there are two accepted methods — but for most students the choice isn't close.

The old **skin test (PPD/Mantoux)** needs two visits: an injection, then a return 48-72 hours later for a nurse to read the reaction. Worse, it produces **false positives in people who received the BCG vaccine** as children — which is most students from outside the US.

The **QuantiFERON blood test (IGRA)** needs one draw, is read objectively by a lab, and is **not affected by BCG vaccination**. The CDC prefers it for BCG-vaccinated people, and virtually all US schools accept it — many now specify it. At [$91.99](https://www.test-well.com/tests/tuberculosis-blood-test) it's the fast path: walk into Quest or Labcorp, no appointment, result in 3-5 business days. The decision detail lives in [the TB blood test guide](https://www.test-well.com/tests/tuberculosis-blood-test#worth-it), the two methods are compared in depth in [blood test vs. skin test](https://www.test-well.com/guides/tb-blood-test-vs-skin-test), and students clearing a registration hold specifically should read [TB test for university enrollment](https://www.test-well.com/guides/tb-test-for-university-enrollment).

If your result comes back positive, don't panic. A positive means your immune system has responded to TB proteins at some point — most often latent TB infection, which is dormant and not contagious. The test itself can't tell latent infection from active disease; that's what the follow-up evaluation and chest X-ray through campus health are for. Schools enroll students with documented latent TB routinely — it's a next step, not a barrier to enrollment.

## Proof of Immunity: Titers When Records Are Lost

The second half of the form is proof of immunity to measles, mumps, rubella, varicella (chickenpox), and hepatitis B. If you have complete, dated vaccination records and your school accepts them, you're done — check before paying for anything. But when records are in another country, another language, or simply gone, a **titer test** is the accepted alternative: a blood test that measures the antibodies already in your blood and documents immunity directly.

- **[MMR Immunity Test](https://www.test-well.com/tests/mmr-immunity-test)** — measles, mumps, and rubella IgG from one draw, reported as immune/non-immune for each. The most-requested titer for enrollment.
- **[Varicella (Chickenpox) Immunity Test](https://www.test-well.com/tests/chickenpox-immunity-test) — $32.99.** Childhood chickenpox almost always leaves lifelong positive titers.
- **[Hepatitis B Immunity Test](https://www.test-well.com/tests/hepatitis-b-immunity) — $31.99.** Quantitative surface antibody (anti-HBs); the common protective threshold is 10 mIU/mL or higher.

All three are standard blood draws with results in 2-5 business days. One format note: the varicella test reports Reactive/Non-Reactive, which most schools accept — but if your program's form says the titer must "show values" (common for nursing and EMT programs), order the [quantitative varicella titer](https://www.test-well.com/tests/varicella-titer-quantitative) ($64.99, Quest) instead. If a component comes back non-immune — mumps immunity in particular wanes with age even in protected people — schools typically ask for a single booster rather than restarting anything; campus health directs that step. The full mechanics, including when it's cheaper to just revaccinate, are in [the titer tests guide](https://www.test-well.com/guides/titer-tests-proof-of-immunity), and the decision layer for MMR specifically is in [the MMR immunity guide](https://www.test-well.com/tests/mmr-immunity-test#worth-it).

## Program-Specific Requirements

Requirements scale with the program. A general undergraduate usually needs TB screening plus MMR and varicella proof. **Nursing, medical, dental, PA, and other health-science programs** almost always require all of the above plus hepatitis B immunity — and they typically want *lab titers*, not just vaccination cards, because clinical placements verify actual immunity.

Two adjacent situations overlap heavily with the school checklist. If you're also going through a green-card process, the [immigration medical exam guide](https://www.test-well.com/guides/immigration-medical-exam-tests) covers the I-693 requirements (TB, syphilis, gonorrhea, and the same vaccination review). And international students clearing a registration hold should start with the [TB test for university enrollment guide](https://www.test-well.com/guides/tb-test-for-university-enrollment), which walks through the portal-upload process end to end.

## Timing Math: Working Backward From Your Deadline

The sequence that clears a health hold on time:

- **Order today.** The requisition is ready within minutes; a licensed physician authorizes it automatically, which is what removes the doctor's-visit step.
- **Get drawn this week.** Quest and Labcorp take walk-ins at 4,000+ locations — use the [lab finder](https://www.test-well.com/find-a-lab) to find one near campus or home. All the titers plus the TB test come from a single draw.
- **Upload in 2-5 business days.** Results arrive as a CLIA-certified PDF with each result, its reference range, and the lab's interpretation — exactly the format campus health portals ask for.

One honest caveat: there's no same-day option for any of these — the TB assay in particular takes lab time. If your deadline is tomorrow, the most useful thing you can do is get the blood draw done *now* so the clock starts; a result in progress is something most registrars will work with, a draw you haven't done yet is not.

## Frequently asked questions

### What TB test do schools and colleges accept?

Virtually all US schools accept the QuantiFERON-TB Gold Plus blood test (an IGRA), and many now prefer or specify it. It needs one visit instead of the skin test's two, is read objectively by the lab, and — critically for international students — isn't thrown off by childhood BCG vaccination the way skin tests are. It's $91.99, drawn at Quest or Labcorp, with results in 3-5 business days.

### Do immunity titers expire?

For most schools, a positive IgG titer on file is accepted as lasting proof of immunity — immunity from childhood vaccination or infection is long-lived, and a documented positive titer generally doesn't need repeating. Some healthcare programs and employers ask for titers drawn within a recent window (often 1-5 years), so check your specific form. Keep the PDF: the same result usually satisfies future requirements too.

### I lost my vaccination records — do I have to get revaccinated?

Not necessarily. A titer test measures the antibodies already in your blood and can prove immunity without any records — if you're immune (most adults vaccinated as children are), the titer is your documentation and no shots are needed. Sometimes revaccinating is simply cheaper and faster, especially if your form accepts a new vaccination card; the titer tests guide walks through when each choice wins.

### Does insurance matter for school health-form testing?

No — these are self-pay lab tests, which is what makes them fast. There's no insurance to bill, no referral, and no doctor's visit: you order online, pay the test price plus a flat $6 physician-review fee, and get drawn at Quest or Labcorp. HSA and FSA cards are accepted if you have one.

### How do I get my results to the school?

Results come back as a CLIA-certified PDF lab report with each antibody result, its reference range, and the lab's interpretation — plus, for TB, the QuantiFERON result — the exact format campus health portals and registrars ask you to upload. You download it from your TestWell account and upload it to the portal; nothing needs to be faxed from a doctor's office.
