|Additional information||This more sensitive assay replaces the NBT test in detecting defects in the generation of peroxide by the monophosphate shunt, and is capable of detecting the carrier state.
The neutrophil oxidative index and the net fluorescence are compared with those of a healthy control and the results are interpreted in a separate report.
This test was developed and its performance characteristics determined by the Clinical Laboratories at the Medical Center at UC San Francisco. It has not been cleared or approved by the U.S. Food and Drug Administration.
An interpretation of this test by a laboratory physician will automatically be performed and billed for separately.
