LEGIGM

IgM antibodies to Legionella pneumophila serogroups 1,6 additional L. pneumophila serogroups (2,3,4,5,6,8) species are measured using an IgM specific conjugate.

We recommend that the IgM test always be performed in conjuction with polyvalent antibody test.

The IgM response to Legionella tends to develop concurrently with the IgG response and may remain elevated as long as the IgG response remains elevated. Cross-reactions have been described with several species of bacteria and mycoplasma.
