Term ID:
3203
Name:
Impaired oxidative burst
Synonym:
Negative NBT reduction test; Negative nitroblue tetrazolium reduction test
Definition:
In the NBT test, neutrophils change the colorless compound NBT into a compound with a deep blue color. If this test is negative (i.e., no blue color is produced), then this indicates a defect in superoxide-generating NADPH oxidase activity with inability to efficiently kill phagocytized bacteria.
