Reference Interval:
#ExistRefRange><1:128 Negative - No significant level of Legionella pneumophila Type 1-6 IgG antibody detected. 1:128 Equivocal - Questionable presence of Legionella pneumophila Type 1-6 IgG antibody detected. Repeat testing in 10-14 days may be helpful. 1:256 or greater Positive - Presence of Legionella pneumophila Type 1-6 IgG antibody detected, suggestive of current or past infection.

| Interpretive Data: |
#ExistInterpData>Seroconversion between acute and convalescent sera is considered strong evidence of recent infection. The best evidence for infection is a significant change on two appropriately timed specimens where both tests are done in the same laboratory at the same time. This assay may detect infection by any of the serotypes 1-6. The CDC and many state health laboratories recommend testing only for antibody to Legionella pneumophila Type 1. For equivocal or positive IFA results, the CDC protocol suggests follow-up testing for Legionella pneumophila antibody Type 1.
