Titer Testing in Charlotte: MMR, Varicella and Hepatitis B
Need proof of immunity for school, work or a healthcare program? Get immunity-related antibody testing for MMR, chickenpox, hepatitis A and B, and tetanus, plus separate hepatitis C infection screening at both OneSpotMD clinics in Charlotte, open 7 days. A provider sees you first, we draw your blood, and many results come back in about 1–3 business days, although timing varies by test and laboratory processing. We can fill out your immunity form. Self-pay is $140 for the visit plus the lab fee for each titer.
Bring your exact requirements: Your school or employer form, vaccine records, required test names and deadline help us order the right tests. Hepatitis C testing is infection screening, not an immunity titer. Do not wait for routine titers after a needlestick or other recent exposure; seek prompt medical evaluation.

What is a titer test?
A titer is a blood test that measures antibodies. For some infections, antibody results can support evidence of immunity, but interpretation depends on the specific test and your vaccination history. Not every antibody test measures protection. Schools, healthcare programs and employers often ask for titers as proof of immunity when vaccine records are missing or out of date.
Titers we offer
| Titer | What it checks |
|---|---|
| MMR | Antibodies to measles, mumps and rubella, interpreted with vaccination records and program requirements |
| Varicella | Varicella antibodies; tests may miss vaccine-induced immunity |
| Hepatitis B | Hepatitis B surface antibody (anti-HBs), interpreted with vaccine history; this is different from infection screening |
| Hepatitis A | Hepatitis A antibodies; the correct test depends on whether immunity or possible acute infection is being assessed |
| Hepatitis C | Hepatitis C antibody screens for possible past or current infection, not immunity. A reactive result needs HCV RNA testing to determine current infection |
| Tetanus | Tetanus antibodies when appropriate; vaccination records and wound care decisions still matter |
We don’t offer polio titers. TB testing checks for TB infection and is not proof of vaccine immunity. Need a TB test too? See TB testing.
Who needs a titer test?
| Who | Why |
|---|---|
| Nursing and healthcare students | Programs ask for proof of immunity before clinicals |
| Healthcare workers | Requirements vary by job; routine repeat immunity testing is not necessary for everyone |
| New hires | Some healthcare companies ask for titers before your start date |
| Patients with symptoms | Symptoms may need diagnostic testing for infection, not an immunity panel. Tell the provider about symptoms or a recent exposure |
Starting a new job? We also do pre-employment physicals and TB testing. See all our occupational health services.
How titer testing works
A negative varicella antibody result can miss immunity after vaccination. Documented vaccine doses may be accepted instead; review your records with the clinician and your program rather than assuming you need another vaccine. Antibody levels can also decline after hepatitis B vaccination without necessarily meaning protection is lost.
Your results
| Result | What it means |
|---|---|
| Evidence of immunity | The result may support immunity for that infection. The provider interprets it with your vaccine records and the receiving program’s requirements. |
| Negative, low or equivocal result | This does not always mean you lack protection. The provider reviews your vaccine history and the test’s limitations before recommending vaccination, repeat testing or other follow-up. |
Have a form?
Bring your school or employer immunity form to your visit. Once results and supporting records are available, we complete the sections we can verify. Your school or employer decides whether the documentation meets its requirements.
Why you shouldn’t wait
Get your titers done early, so a delay doesn’t hold up your start date.
| If you wait | What can happen |
|---|---|
| Waiting until right before your deadline | Results may take several business days, and additional documentation, vaccination or testing can take longer |
| Missing vaccine records | Without records or titers, your program or job may not clear you to start |
| Symptoms like yellow skin or eyes, or dark urine | These can be signs of hepatitis and need to be checked |
How much does a titer test cost?
- Copay: your plan’s copay amount is due at the visit when applicable.
- Coinsurance: your share depends on your plan and services.
- Deductible: your plan may apply a deductible; additional patient responsibility may be billed after insurance processes the claim.
- NC Medicaid plans: we accept most NC Medicaid plans. Copays for covered visits are usually $0 or $4; lab coverage and costs may differ. Confirm with your plan.
- Titers: coverage depends on the test, reason, coding, laboratory network and your plan. If your school or employer requires them, your plan may not cover them. Check with your insurance.
Self-pay prices
These are discounted prices for patients who don’t have insurance or choose not to use it.
The visit is $140, plus the lab fee for each titer. Each titer has its own price, depending on the test. For tests included in the agreed self-pay arrangement, lab fees are collected at the visit. Confirm whether additional or follow-up tests would have separate charges. See every price on our self-pay price list and all the plans we take on our insurance page.
