Component

L. pneumophila (Types 1-6), Antibodies ≤0.90 IV      Negative: No significant amount of IgG/IgM/IgA antibodies to L. pneumophila detected.
0.91 to 1.09 IV  Equivocal: Recommend repeat testing in 1-3 weeks with fresh sample.
≥1.10 IV      Positive: IgG/IgM/IgA antibodies specific to L. pneumophila suggesting current or prior infection. A positive result cannot distinguish between previous or active infection, therefore this result alone cannot be used to establish a diagnosis.
