WebHistorically, calculations were used to correct the nucleated cell count for the presence of red blood cells. The theory was that a specific number of the nucleated cells present were peripheral WBCs that had been introduced into the CSF along with the red cells, thus inflating the nucleated cell count and perhaps indicating a false meningitis. WebRed blood cell count. Normally, there are no RBCs or nearly none (<1 RBC/mm 3). 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("bloody tap") can result in RBCs being present in the CSF, the blood will progressively clear with each tube of CSF withdrawn.
