I posted a thread a few days ago about my son's condition. We have received his test results for the neutrophil oxidative burst test. The results took 3 weeks to come back when they were supposed to have taken one. When they returned, it said that my son had 0 granulocytes and the test needed to be redone. Are they redoing it to make sure he really has none? Did they mess up the blood sample? If they had messed it up, wouldn't they have just said they couldn't test his blood? A normal range of granulocytes in a person's body is >76%. Is it possible for someone to have none?
