If you’re searching for a titer blood test near me, CityHealth San Leandro offers on-site immunity testing with fast turnaround. Whether you need titers for school enrollment, a healthcare job, immigration, or personal peace of mind, we can draw your blood and order the right panel — all in one visit, no referral needed.
This guide covers everything you need to know about titer testing: what titers are, why you might need them, which diseases are tested, how the process works, and what to expect with results and cost.
What Is a Titer Blood Test?
A titer (pronounced TIE-ter) is a measurement of the level of antibodies in your blood against a specific disease. Antibodies are proteins your immune system produces after exposure to an infection — either from having the disease or from a vaccine.
When you get a titer test, a lab measures how much of these antibodies are present. A result above a certain threshold means you’re immune — your body can fight off that disease. A result below the threshold means you may not have sufficient immunity, and a booster vaccine may be recommended.
Titer tests don’t tell you if you have a disease right now. They tell you whether your immune system has the memory and tools to fight it off if you were exposed.

Why Do People Need Titer Tests?
Titer tests are required in a growing number of situations. Here are the most common:
School and University Enrollment
Many colleges and universities — especially those with nursing, medical, or dental programs — require proof of immunity to diseases like measles, mumps, rubella, and varicella before enrollment. Vaccination records are the first choice, but if records are lost or incomplete, a titer test is accepted as proof of immunity.
Healthcare Worker Clearance
Hospitals, clinics, nursing homes, and other healthcare facilities typically require titer testing for all new employees. Healthcare workers are in close contact with vulnerable patients, so facilities need assurance that staff are immune to diseases like hepatitis B, MMR, and varicella. This is often required annually or upon hire.
Immigration Medical Exams
The USCIS immigration medical exam (Form I-693) requires proof of vaccination or immunity for a set list of diseases. If records are unavailable, titer testing can satisfy that requirement. USCIS-designated civil surgeons administer these exams — ask us if we can assist with the immigration process.
Pregnancy Planning
Rubella (German measles) and varicella (chickenpox) can cause serious birth defects if contracted during pregnancy. Women planning to become pregnant often get titer tests to confirm immunity before conception — because vaccination isn’t safe during pregnancy.
International Travel
Some countries require proof of vaccination for certain diseases before entry. Titer testing confirms immunity for travelers who may not have complete records.
Personal Verification
Some people simply want to know their immune status — whether childhood vaccinations are still effective decades later, or whether they developed immunity after exposure to a disease.
Which Titer Tests Are Available at CityHealth?
CityHealth San Leandro offers the most commonly required titer panels. Here’s what we test and why:
MMR Titer (Measles, Mumps, Rubella)
The MMR titer tests for immunity to all three diseases with a single blood draw. Measles is highly contagious — the MMR vaccine is one of the most important public health tools we have. Schools, universities, and healthcare employers commonly require this panel.
Varicella Titer (Chickenpox)
Varicella testing checks for immunity to chickenpox. Most people who had chickenpox as a child are immune, and many vaccinated individuals are as well. If you’ve had two doses of the varicella vaccine, you’re likely immune — but a titer can confirm this if records are unavailable.
Hepatitis B Titer (Hep B Surface Antibody)
Hepatitis B titers are commonly required for healthcare workers. The test checks for surface antibodies (anti-HBs) that develop after vaccination or infection. A result of 10 mIU/mL or higher is generally considered immune. Some people require a booster series if levels are low.
Hepatitis A Titer
Hepatitis A titers are used in food service, travel medicine, and some healthcare settings to confirm immunity. The Hep A vaccine series provides strong, long-lasting protection — but if records are incomplete, titers confirm immune status.
Other Titers Available
We can also order panels for tetanus/diphtheria antibodies, polio titers, and other specific requirements. If you have a specific institutional requirement, bring the documentation and we’ll match the right test to it.
How the Titer Test Process Works at CityHealth
The process is straightforward. Here’s what to expect:
- Schedule your visit — Book online or walk in. No referral needed.
- Tell us which titers you need — Bring any documentation from your school, employer, or institution if available.
- Blood draw — A quick venipuncture by our trained staff. Most draws take under 5 minutes.
- Lab processing — We use our on-site and partner labs for fast processing.
- Results — Most results are available within 1–3 business days. We’ll notify you and provide official documentation.
You don’t need to fast for most titer tests. Come in any time during our hours and we can draw your blood the same day.
Titer Test Results: What They Mean
Each test has a defined threshold that determines immunity:
- Immune (positive): Your antibody level is at or above the threshold. You’re considered protected. You’ll receive documentation confirming immunity.
- Non-immune (negative): Your antibody level is below the threshold. You’ll likely need a booster vaccine or a full vaccination series, depending on which disease and your history.
- Equivocal: Your level falls in an uncertain range. The lab or your provider may recommend a repeat test or vaccination.
If you need a booster vaccine after getting a non-immune result, CityHealth can often administer it the same day or at a follow-up visit. Ask about vaccine availability when you come in.
Titer Test Cost at CityHealth San Leandro
Titer test costs vary depending on which panels are ordered and your insurance coverage. Here’s what to expect:
- With insurance: Titer tests may be covered as preventive care or occupational health services. Coverage depends on your specific plan — confirm with your insurer.
- Without insurance (cash pay): Individual titer tests typically run $30–$80 per disease tested. A full 4-panel package (MMR + varicella + Hep B + Hep A) may cost $150–$250 out of pocket.
We can give you a cost estimate at the time of your visit. We don’t believe in surprise bills — ask upfront and we’ll tell you what to expect.
