FIG. 2.

Serum glucan levels were significantly increased in ICU patients with confirmed infections compared to levels in normal controls and ICU patients without infections. However, assaying serum glucan levels did not appear to be specific for the presence of fungal infections, since glucan levels were increased in ICU patients with either fungal or bacterial infections. A 20-pg/ml cutoff was established based on the normal control values. The data are presented as individual patient values. The bars show the mean value for each group.
