Rubella IgG antibodies
- This test is used to screen for Rubella immunity. As from 01/04/16, following the decision of Public Health England and the Department of Health , Rubella immunity is no longer routinely tested for as part of an antenatal screen. Please contact the laboratory if there is a clinical need for testing.
- If Rubella infection is suspected, please request Rubella IgM antibodies
- Satisfactory evidence of Rubella immunity is defined as:
- at least two previous Rubella IgG antibodies screening tests with detectable antibody greater than 10 iu per ml or;
- at least two documented doses of Rubella vaccine or;
- one documented dose of vaccine followed by one Rubella IgG antibody screening test with detectable antibody greater than 10 iu per ml
- Antibody levels may fall with time. Providing that the criteria above are met a subsequent negative antibody test does not indicate loss of immunity.
- When blood is submitted for rubella antibody testing, results should be reviewed together with vaccination history and previous results.
- Second Rubella infections despite immunity, have been documented. If there is clinical suspicion (especially in pregnancy) please contact the Consultant Microbiologist to discuss.
