Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Reference Range: <1:16
IgM antibodies to Legionella pneumophila serogroup 1 and 6 additional L. pneumophila serogroups (2,3,4,5,6,8) are measured using an IgM specific conjugate. We recommend that the IgM test always be performed in conjunction with the 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.
