The Measles IgG Titer test measures antibodies in your blood to determine immunity against measles. A positive result means you are protected, while a negative result may indicate the need for vaccination. This test is important for healthcare workers, travelers, and students in clinical settings.
A Quantitative Measles IgG titer is a blood test that measures the level of antibodies against the measles virus (rubeola) in your bloodstream. This test determines whether you have immunity to measles, either from prior vaccination or past infection.
Purpose: The test checks for protective immunity, which is especially important for individuals at high risk of exposure (e.g., healthcare workers, travelers, or students in clinical settings).
Interpretation:
Positive titer: Indicates immunity to measles, meaning you are protected against infection.
Note: This test does not diagnose an active measles infection—it only assesses immunity. If measles infection is suspected, additional testing (such as IgM antibodies or PCR) may be needed.
