Rubella Serology

Alias: German Measles

Discipline: Virology

Test information: Rubella (German measles) is a viral infection that's now rare in the UK due to the introduction of the MMR vaccine. Rubella serology is performed for the assessment of immunity, usually as part of an occupational screen where MMR vaccination status is uncertain.

It may also be used to assess the susceptibility of contacts of suspected or proven cases of Rubella - particularly pregnant women. Please note Rubella immunity is not routinely available as part of the routine antenatal booking screen in accordance with the IDPS guidance. Full Rubella IgM and IgG serological profile is available by referral for clinical investigations.
