FAQ
Frequently asked questions
What is rubella?
Rubella, also known as German measles, is a contagious viral infection. While often mild, it can cause serious problems if contracted during pregnancy, especially for the developing fetus.
How does this test confirm immunity?
The test detects IgG antibodies, which are produced by your immune system after exposure to the virus or after receiving a vaccination. The presence and level of these antibodies suggest immunity.
What does a 'titer' mean?
A titer refers to the amount or concentration of antibodies in the blood. A higher titer generally indicates a stronger immune response and potentially greater immunity.
Can this test be done at home?
This test requires a blood sample to be collected by a trained healthcare professional. While you may order the test online, the sample collection must be done at a designated lab or clinic.
