Rubella IgG is used to assess evidence of previous immunity, including in pregnancy planning. It answers a different question from diagnosis of recent infection.

Understanding the test
Also called Rubella Immunity (IgG)
Rubella IgG may be checked before or during pregnancy to assess evidence of immunity. It is different from investigating a new exposure or symptoms in pregnancy.
Rubella IgG is commonly used when immunity status matters in pregnancy planning or antenatal care.
Your clinician can interpret the level against your vaccination record and circumstances.
Before your sample
No fasting is required. Bring vaccine records and tell the team about pregnancy, pregnancy planning or a recent exposure.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

The antibody can reflect either vaccination or previous infection. The treating clinician advises on next steps according to pregnancy status, vaccine records and exposure history.

Explore Smart Report
Discuss the report with your maternity or preconception team, including any known exposure and available vaccine records.
Patient questions
Contact your maternity clinician promptly and give the exposure date. A single IgG test alone cannot reliably date a new infection.
Your clinician reviews documented doses and the antibody result together. Checking IgG helps assess immunity. Vaccination, when appropriate, provides protection.
Rubella infection in early pregnancy can harm a developing baby. Before or after pregnancy, a clinician can advise on vaccination if needed. Live rubella vaccine is not given during pregnancy.
