Details about Rubella Antibody (IgG) Immunity
What is the Rubella Antibody (IgG) Immunity test?
The Rubella Antibody (IgG) test measures IgG antibodies against the rubella virus, indicating whether a person has protective immunity. Immunity usually develops after vaccination (MMR) or previous infection.
Rubella is generally mild in children and adults, but infection during pregnancy—especially in the first trimester—can cause congenital rubella syndrome, leading to severe fetal complications.
This test does not diagnose active infection. It is specifically used to confirm immune protection.
Why do I need a test for Rubella Antibody (IgG)?
Confirming rubella immunity is especially important for women planning pregnancy, healthcare workers, and individuals without documented vaccination history.
Knowing your immune status helps prevent avoidable risks and guides vaccination decisions.
You may benefit from this test if you:
-
Are planning pregnancy or are in early pregnancy
-
Need confirmation of rubella immunity
-
Have no vaccination records
-
Work in healthcare, childcare, or education
-
Are undergoing fertility treatment
-
Need immunity screening for employment or travel
-
Want reassurance before conception
-
Require pre-pregnancy screening

Your Rubella Antibody (IgG) results explained
Non-immune (IgG not detected)
A negative or low IgG result indicates no confirmed immunity to rubella. This means you may be susceptible to infection.
Vaccination may be recommended, particularly before pregnancy.
UK reference interpretation:
-
Non-immune: IgG below protective threshold
Immune (IgG detected)
A positive IgG result confirms protective immunity against rubella. This indicates successful vaccination or past infection and provides reassurance for pregnancy planning.
UK reference interpretation:
-
Immune: IgG above protective threshold
High IgG levels
High IgG levels indicate strong or long-standing immunity. This is expected following vaccination or previous exposure and is not harmful.
UK reference interpretation:
-
High: Well above protective level

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
