Affordable titer testing.
A titer is a laboratory test that measures the presence and amount of antibodies in blood.
Most schools in the United States require students to provide proof that they are up to date on their vaccinations before they can start attending school.
If vaccination records are unavailable, an individual may have blood titers drawn to show that your body is protected against specific infections and diseases.
In many cases getting titers can be an affordable way to meet mandatory vaccination requirements of schools or employers.
