Impaired oxidative burst (HP:0003203)help
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.
