Webpleocytosis was defined as CSF nucleated cell count (NCC) >5 cells/μL with >40% of the NCC being neutrophils, ... For cases with CSF red blood cell (RBC) counts >500 cells/μL, the NCC was adjusted by calculating and subtracting the number of leukocytes expected from peripheral blood contamination, using the ratio of 1 leukocyte to 500 RBCs. WebThe presence of red blood cells (RBCs) in the CSF is frequently used to differentiate patients with intracerebral hemorrhage from those with cerebral in-farction (table 3). In four patients with intracerebral hemorrhage in whom the CSF was clear, the RBC counts were less than 3,000 per cubic millimete (0r , 72 , 840, and 2,170 per cubic ...

Any cell that is found in the bone marrow, including megakaryocytes and blasts, can be seen. A differential should not be reported on CSF con-taminated with bone marrow but a note that “bone marrow contamination suspected” should be reported instead.

While a traumatic lumbar puncture ("bloody tap") can result in RBCs being present in the CSF, the blood will progressively clear with each tube of CSF withdrawn.
