Measles, Mumps, Rubella, Varicella

MMR/VZV titers are blood tests that measure IgG antibodies to measles, mumps, rubella, and varicella-zoster (chickenpox). Programs often require proof of immunity for school, healthcare employment, travel, or clinical rotations. Titers can also confirm a post-vaccination response or help guide planning for pregnancy when rubella or varicella immunity is uncertain.

A proactive approach is simple: order the exact titers your form requests, draw blood ≥3–4 weeks after vaccination (if you just completed a series or booster), and compare results with the assay’s ... See more

The MMR Titer Test is a quantitative blood test that measures antibody levels to measles, mumps, and rubella. Results provide exact antibody values to confirm prior infection or response to vaccination. Low levels suggest lack of protection, while higher levels indicate adequate response. Doctors order this test for school, employment, or travel requirements and to guide revaccination decisions, ensuring accurate evaluation of immune status against these viral diseases.

Also Known As: MMR Immunity Test, Measles Mumps Rubella Titer, Measles Mumps Rubella IgG Antibodies

The Measles, Mumps, Rubella (MMR) Immunity Profile is a quantitative blood test that measures antibody levels to measles, mumps, and rubella. Results confirm prior infection or vaccine response and show if antibody levels are protective. Doctors order this test for school, employment, or travel requirements, to evaluate vaccine effectiveness, and to guide revaccination decisions. It provides reliable assessment of immune protection against all three viral diseases.

Also Known As: MMR Titer Test

The Measles IgG IgM Antibodies Test measures immune response to the measles virus by detecting IgM for recent or acute infection and IgG for past exposure or vaccine immunity. This test helps confirm suspected measles cases in patients with fever, rash, cough, or conjunctivitis, and evaluates immunity in those with uncertain vaccination history, supporting diagnosis, outbreak control, and public health monitoring.

Also Known As: Rubeola Test, Measles Virus Test, Measles Titer test, Measles Infection Test

The Measles IgG Antibody Test measures IgG antibodies to determine immunity from past infection or vaccination. A positive result indicates protective immunity, while a negative result suggests susceptibility to measles. Doctors use this blood test to confirm immune status, evaluate vaccination records, or meet school, travel, or employment requirements. It provides valuable insight into measles protection and public health safety.

The Measles IgM Antibody Test detects IgM antibodies specific to the measles virus, providing evidence of recent or acute infection. IgM antibodies typically appear shortly after exposure and indicate an active immune response. This test is used to confirm measles in symptomatic patients, support outbreak investigations, and distinguish between current infection and prior immunity, aiding timely clinical and public health decisions.

The Measles Titer Test measures IgG antibody levels to determine immunity from prior measles infection or vaccination. A positive result indicates protective immunity, while a negative result suggests susceptibility. Doctors order this test to confirm immune status for school, healthcare, travel, or employment requirements. It is also used to verify vaccination response, ensuring individuals are protected against measles and reducing outbreak risk.

The Mumps Virus Titer Test measures IgG antibodies to determine immunity from prior infection or vaccination. A positive result indicates protective immunity, while a negative result suggests susceptibility to mumps. Doctors use this blood test to confirm immune status, check vaccine response, or meet school, travel, or employment requirements. It provides valuable information for individual protection and public health safety.

The Rubella IgG IgM Antibodies Test measures antibodies to the rubella virus, helping evaluate immunity or recent infection. IgM indicates an active or recent infection, while IgG confirms past infection or vaccination. Doctors use this test to assess immune status in women of childbearing age, screen during pregnancy, or confirm suspected rubella exposure, as infection can cause serious complications for unborn babies.

Also Known As: Rubella Titer, Rubella Antibodies Test, German Measles Test

The Rubella IgM Antibody Test measures immune response to the rubella virus by identifying IgM antibodies produced soon after exposure. Detection of rubella IgM helps diagnose recent infection, assess rash-related illness, and monitor risk in pregnancy where congenital rubella syndrome may occur. This test provides valuable insight into acute infection, immunity status, and systemic health.

The Rubella Titer Test measures IgG antibodies to determine immunity to rubella (German measles). A positive result indicates protection from prior infection or vaccination, while a negative result suggests susceptibility. Doctors order this test for women planning pregnancy, healthcare workers, students, or travelers. It helps confirm immune status, guide vaccination needs, and protect against congenital rubella syndrome and outbreak risks.

The Total T and B Cells Test measures levels of T lymphocytes and B lymphocytes, key white blood cells essential for immune defense. Abnormal counts may indicate immune deficiencies, autoimmune disorders, infections, or blood cancers. Doctors use this test to evaluate immune system function, diagnose underlying conditions, and monitor treatment. It is often ordered with other immune panels to provide a comprehensive view of adaptive immunity.


The Varicella Zoster Virus IgG IgM Antibodies Panel is used to assess exposure to the varicella-zoster virus, which causes both chickenpox and shingles. By evaluating the presence and levels of specific antibodies, this panel aids in diagnosing current infections, determining immunity, and guiding vaccination decisions.

The Varicella Titer Test is a blood test that measures antibodies to the varicella-zoster virus (VZV), which causes chickenpox and shingles. A positive result indicates past infection, while a negative suggests no exposure. This test is not considered reliable for confirming immunity from vaccination. Doctors use it to evaluate history of natural infection, meet school or work requirements, and provide documentation of varicella exposure status.

The Varicella IgM Antibody Test measures IgM antibodies produced in response to varicella-zoster virus, helping identify current or recent chickenpox infection. It aids in differentiating acute illness from prior exposure or immunity. This test supports evaluation of symptoms such as rash, fever, or fatigue, and provides valuable information about immune activity and viral health risks.

Before the MMR vaccine became available, three to four million people contracted measles every year in the United States. The CDC estimates that 400 to 500 people died among reported cases, 48,000 were hospitalized, and 1,000 developed brain swelling each year.

While the United States declared measles eliminated from the country in 2000, there are still outbreaks from time to time. In addition, if vaccine coverage levels were to drop, measles could once again become a constant presence. 

If you think you've been exposed to someone with measles, you'll benefit from undergoing an MMR titer test to understand if you have immunity.

Defining Measles, Mumps, Rubella (MMR)

One of the first written accounts of measles is from the ninth century by a Persian doctor. However, in 1757, Francis Home, a Scottish doctor, determined that an infection causes measles in the blood. 

In 1912, the United States declared measles ... See more
