Clinical Utility

The measure of oxidation is a useful assay in the diagnosis of chronic granulomatous disease and is also a useful means to determine the overall metabolic integrity of phagocytizing neutrophils.

Procedure

The level of reactive oxygen radicals is determined by flow cytometry. This test has not been cleared or approved for diagnostic use by the U.S. Food and Drug Administration.
