Csf red blood cell correction
WebJul 1, 2011 · We sought to determine the relationship between cerebrospinal fluid (CSF) protein and CSF red blood cells in children with traumatic lumbar punctures. For every 1000 cell increase in CSF red blood cells per mm 3, CSF protein increases by 1.1 mg/dL (95% CI, 0.9-1.1 mg/dL). 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.

By the third tube, the CSF should be nearly clear, even with a bloody tap.
