What is the normal range for rubella IgG and IgM?
10 IU/mL or greater: Detected. 19.9 AU/mL or less: Not Detected. 20.0 – 24.9 AU/mL: Indeterminate – Repeat testing in 10-14 days may be helpful. 25.0 AU/mL or greater: Detected – IgM antibody to rubella detected, which may indicate a current or recent infection or immunization.
How do you read a titer result?
The USDA considers a titer of ≥1:4 to be positive. A result of <1:2 is equivalent to a negative @ 1:4 or 1:8 result. A titer of >1:128 may indicate recent infection. A titer of ≥1:320 may indicate recent infection.

Confirm your immunity to measles, mumps, and rubella with a simple blood test. Individuals that have received the MMR vaccine can confirm and prove immunity to these diseases with our immunity screening. Best of all, no doctor’s order or insurance is required to order your test.
What are high titers?
In certain conditions, a low titer may essentially indicate the efficient removal of infectious pathogens by the immune system. In contrast, a high titer may simply be due to the presence of residual antibodies from a previous infection, or unsuccessful attempts to form antigen-antibody complexes.
What do titer numbers mean?
A titer is a measure of how much a sample can be diluted before antibodies can no longer be detected. Titers are usually expressed as ratios, such as 1:256, meaning that one part serum to 256 parts saline solution (dilutant) results in no antibodies remaining detectable in the sample.
