Question

Why must you get the rubella titer for rubella?

a) To confirm recent infection
b) To assess immunity status
c) To diagnose active disease
d) To monitor treatment response

Answer 1

The rubella titer is used to assess an individual's immunity status against rubella, which is crucial for healthcare workers to ensure they do not spread the disease to susceptible patients.

Step-by-step explanation:

You must get the rubella titer to assess immunity status. The rubella titer is part of the MMR titer test, which indicates whether an individual has a sufficient level of antibodies against measles, mumps, and rubella to be considered immune. This test is crucial for healthcare workers to prevent the spread of these diseases to vulnerable populations. The MMR vaccine is typically administered during childhood, but immunity can wane over time. Consequently, a titer test is required to confirm if an individual still has immunity or needs another dose of the vaccine. If a healthcare worker's titer is low, they may need to be re-vaccinated before starting work.
