What this test is
This test measures the level of antibodies in your blood that fight specific diseases. It is commonly used to see if you are already immune to conditions like measles, mumps, rubella, hepatitis, or chickenpox. The results can help determine if you might need a booster vaccine.
What it measures
- Antibody level — Reflects the amount of specific antibodies in your blood
- Immune status — Indicates whether you are likely protected against a disease
- Titer value — Shows the concentration of antibodies present
What the test involves
A healthcare professional collects a small sample of blood, usually from a vein in your arm. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to check if you are protected against certain diseases before travel, school, or work. It can also help determine whether a previous vaccination was effective or if you need additional doses.
Preparation
In most cases, no special preparation is needed, but you should follow the specific instructions provided by the collection lab. This may include fasting or avoiding certain medications, depending on the test.
How results are reported
Results are typically reported as a numerical value that indicates your antibody level, often with a note about whether it is considered protective. Reference ranges can vary between laboratories, so your results should be interpreted in the context of the lab's own guidelines.
