Rubella Immunity & Antibody Blood Test (IgG / IgM)

Rubella (German measles) is usually a mild illness, but infection during pregnancy can cause serious harm to a developing baby, including miscarriage, stillbirth, and congenital rubella syndrome. This blood test checks whether you have antibodies against rubella, which shows whether you are protected or whether you may have been recently exposed.

It is suitable for anyone who wants to confirm their immunity, particularly women planning a pregnancy, pregnant women with no documented vaccination history, healthcare workers, and people who have had close contact with a confirmed case. A simple blood sample is all that is required.

Rubella Antibodies

• Rubella IgG: Detects past infection or vaccination. A positive result generally indicates immunity and protection against future infection.
• Rubella IgM: Detects recent or current infection. A positive result may suggest acute infection and is usually interpreted alongside IgG and clinical history.

Why it matters

Knowing your rubella immunity status allows you to take action before or during pregnancy. If you are not immune, vaccination can be arranged before conception. If recent infection is suspected, prompt clinical review helps protect both mother and baby. For healthcare workers, documented immunity supports occupational health clearance and safe practice.
