What does high rubella AB IgG mean?
Positive: A positive rubella IgG test result is good—it means that you are immune to rubella and cannot get the infection. This is the most common rubella test done. Negative: This means you are not immune to rubella.
What is rubella IgG and IgM?
When the body is infected with the rubella virus, it defends itself by producing two types of antibodies in sequence: first, IgM, which appears 3 to 7 days after the onset of symptoms and is present for a few weeks, then IgG, which appears a few days after IgM and lasts for the rest of that person’s life.
What is rubella IgG normal range?
Reference Range: 7 IU/mL or less: Negative – No significant level of detectable rubella IgG antibody. 8-9 IU/mL: Equivocal – Repeat testing in 10-14 days may be helpful. 10 IU/mL or greater: Positive – IgG antibody to rubella detected, which may indicate a current or previous exposure/immunization to rubella.
What if rubella IgM is positive in pregnancy?
Tests for rubella IgM are not indicated unless there is a history of rash in a pregnant woman or contact with a rubella-like rash. Unnecessary tests for rubella IgM may lead to problems in interpretation, because the positive predictive value of rubella IgM results has declined in countries where rubella seldom occurs.
What is the normal range of rubella IgM pregnancy?
0.8 AI or less: Negative – No significant level of detectable rubella IgM antibody. 0.9-1.0 AI: Equivocal – Repeat testing in 10-14 days may be helpful. 1.1 AI or greater: Positive – IgM antibody to rubella detected, which may indicate a current or past rubella infection.
