Start from the immunity you need to document

Each of these answers a different immunity question, depending on what you must document.

An immunity titer test measures antibodies linked to prior vaccination or past exposure, helping document immune status for a school, employer, clinical program, travel requirement, or personal record. Options differ by the antibodies measured: measles, mumps, and rubella IgG; hepatitis B surface antibody; varicella-zoster IgG; or rabies vaccine response. Start with the requirement you need to meet and identify whether it calls for one infection-specific result, MMR results, or several immunization-related antibodies. A result should be reviewed with the requesting organization or a healthcare professional when documentation rules or symptoms matter.

What immunity antibody tests measure

These tests look for antibodies associated with specific infections or vaccines rather than measuring overall immune strength. Measles, mumps, and rubella immune-status testing measures IgG antibodies to each of those three viruses. Hepatitis B surface antibody testing measures hepatitis B surface antibody immunity quantitatively. Varicella-zoster virus IgG testing measures an antibody associated with chickenpox immunity. The rabies vaccine response end-point titer reports the response named in the test. Antibody findings support documentation and clinical assessment, but the organization requesting records determines what result format and timing it accepts.

Use the requested disease and result format

A requirement for MMR documentation calls for results tied to measles, mumps, and rubella, not a single general antibody result. The Measles, Mumps, Rubella (MMR) Immunity Profile reports all three IgG immune-status measurements. When a requirement names hepatitis B, the Hepatitis B Surface Antibody Test provides a quantitative hepatitis B surface antibody result, while a chickenpox requirement aligns with varicella-zoster virus IgG. The Immunization Panel combines hepatitis B surface antibody immunity with measles, mumps, rubella, and varicella-zoster IgG results for shoppers asked to document several immunization-related antibodies at once.

Immunity & Titer Testing FAQ

A titer test measures a specific antibody or vaccine-response result, not general immune performance. In this group, available measurements include measles, mumps, rubella, and varicella-zoster IgG; hepatitis B surface antibody; and rabies vaccine response end-point titer. The requested disease, vaccine, or documentation rule determines which result is relevant.

The Measles, Mumps, Rubella (MMR) Immunity Profile measures IgG immune status for measles, mumps, and rubella. The Immunization Panel measures those same three IgG results plus hepatitis B surface antibody immunity and varicella-zoster virus IgG. The panel fits a request covering several immunization-related antibodies; the MMR profile fits documentation limited to those three viruses.

Hepatitis B surface antibody testing measures antibody immunity, whereas tests for hepatitis B infection use different laboratory targets. The Hepatitis B Surface Antibody Test reports hepatitis B surface antibody immunity quantitatively. A result alone does not diagnose an infection or explain vaccination history; a healthcare professional can determine whether additional hepatitis B testing is appropriate.

Varicella-zoster virus IgG measures an antibody associated with chickenpox immune status. The Varicella-Zoster Virus (VZV) Antibodies, IgG (Chickenpox) test is suited to a requirement specifically asking for varicella or chickenpox IgG documentation. It is different from a test named for varicella IgM, which addresses a different antibody class and does not replace an IgG immunity result.

A rabies vaccine response end-point titer is relevant when the request specifically names rabies vaccine response or an end-point titer. It measures the rabies response identified in the product name, rather than measles, hepatitis B, or varicella antibodies. Confirm the requested test name and reporting expectations with the organization that needs the documentation.

An IgG result indicates that the laboratory detected the antibody measured, but it does not independently settle every protection or documentation question. Requirements can specify an accepted test, threshold, date, or record format. Recent vaccination timing, prior records, and the reason for testing help a healthcare professional or requesting organization interpret the result.

Quantitative hepatitis B surface antibody testing reports an amount for hepatitis B surface antibody immunity rather than only a detected-or-not-detected classification. That format is useful when a form or reviewer asks for a numerical result. The Hepatitis B Surface Antibody Test measures this quantitative antibody result; interpretation depends on the purpose of testing and the standard being applied.
