Measles IgG:
What is Measles IgG?
Measles IgG is an antibody that is produced by the body in response to a measles infection. It is an indicator of whether the person has been exposed to the measles virus and is considered the most reliable way to determine immunity.
What is a Normal Measles IgG Level?
A normal Measles IgG level is generally accepted to be above 0.9 IU/mL or higher. A measles IgG level of 1.0 IU/mL or higher is considered to be indicative of immunity, while levels below 0.9 IU/mL indicate the person may not be immune and should consider receiving the measles vaccine.
What is the Measles IgG Test Used For?
The Measles IgG test is used to determine if a person has been exposed to the measles virus and is therefore immune, or if the person should receive the measles vaccine for protection. This test is used in instances where a person has not been vaccinated or is unsure if they have been vaccinated. It is also used to confirm a measles diagnosis in cases of suspected measles infection.
What is the Difference Between Measles IgG and Measles IgM?
Measles IgG is an antibody produced in response to a measles infection, while Measles IgM is a marker of a current infection. While Measles IgG is used to determine immunity, Measles IgM is used to diagnose an active infection.
