Convalescent-phase serums were needed to support confirmation in three cases. When available, CSF samples from acute-phase cases also yielded positive WN virus IgM results, although testing at a lower dilution than for serum was necessary.

Gamma globulin from the serum of normal subjects or patients convalescent from hepatitis agglutinated collodion particles sensitized with acute-phase serums obtained from patients with viral hepatitis or certain other acute infectious diseases.

Selenium concentrations in the serums of 17 acutely ill Legionnaires' disease patients were significantly lower than in their matching convalescent-phase serums. This trend was not observed in ten similarly paired samples of serum from control patients with pneumonia.
