Rubella Virus IgG Antibody
- Sample Type
- Standard
- Fasting
- No
- Unit
- IU/mL
This test measures the level of Immunoglobulin G (IgG) antibodies to the Rubella virus. Within an MMR Profile, it is used to determine immune status. A positive result indicates long-term immunity, either from a previous infection or successful vaccination. For pregnant women, ensuring Rubella immunity is critical because primary Rubella infection during the first trimester can lead to Congenital Rubella Syndrome (CRS), causing severe birth defects, deafness, or fetal demise.

Why Context Matters
Interpretation can be complex in patients who have recently received the MMR vaccine or those with borderline/equivocal titers. Cross-reactivity with other viruses can occasionally cause false positives, and very early testing after exposure may yield a negative result before seroconversion occurs.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
