1. The abnormal cells of leukemia are definitive for the disease.
2. A lumbar puncture can increase ICP, not diagnose it.
3. Staging is done with blood cells, not cerebral spinal fluid.
4. If a child has a known diagnosis of leukemia, the lumbar puncture does not need to be done to identify meningitis unless other blood tests indicate infection.
