Laboratory: Clinical Immunology
Test Name:
OXIDATIVE BURST - (B)
Test Code: OBRT
Clinical Information:
Chronic Granulomatous disease (CGD) is an inherited primary immunodeficiency disorder characterized by severe, recurring infections with formation of granulomas.  Phagocytic cells ingest, but cannot digest bacteria or fungi due to a malfunction of the nicotinamide adenosine dinucleotide phosphate (NADPH) oxidase system.
 
Patients treated with acetaminophen have decreased neutrophil oxidative burst as measured by DHR testing. To avoid falsely abnormal testing for CGD, patients should be advised to avoid acetaminophen for at least 24 hours prior to DHR testing.
