Measles titer: a titer of igG of less than 9 means there was no previous exposure to measles or there was a previous exposure but the immunoglobulin level is decreasing, the level does not discriminate between post exposure to the actual virus or from immunization. Someone who is vaccinated against measles will have a high IgG level that is greater than 9 ( in this case 24.7)

Low IgM value means no current or very recent infection.

IgG: Elevation of your IgG means you are immunized. It follows the elevation of the IgM which occurs when you have an acute case of the measles. All the best.
