MUMPS IgG ANTIBODY

Mnemonic

MUMPS IGG AB

Synonym

Mumps - Mumps IgG

Guidelines

Mumps, a paramyxovirus, causes a communicable, self-limiting disease transmitted by airborne droplets. Primarily a disease of children aged 4-15, mumps is also the most common cause of aseptic meningitis in childhood. The detection of IgG antibody can be used to show immunity and detect seroconversion.

Please see Updated Investigative Guidelines for Mumps from Oregon Health Authority, Public Health Division.
