No interference of the 1,3-β-D-glucan containing nutritional supplement ImunixX with the 1,3-β-D-glucan serum test.

The detection of 1,3-β-D-glucan serum levels may permit establishing the diagnosis of invasive fungal infections more early. We tested in six healthy volunteers whether the intake of a 1,3-β-D-glucan-containing nutritional supplement leads to false-positive 1,3-β-D-glucan levels. All levels were negative, even in two different dosing regimens.
