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("bloody tap") can result in RBCs being present in the CSF, the blood will progressively clear with each tube of CSF withdrawn. By the third tube, the CSF should be nearly clear, even with a bloody tap. WebThe growth-associated protein 43 (GAP-43) is a presynaptic phosphoprotein in cerebrospinal fluid (CSF). The ε4 allele of apolipoprotein E (APOE) is an important genetic risk factor for Alzheimer’s disease (AD).

Web(example: 111 is average), so My calculation is ((average number of cells counted x dilution factor)/(2 x 10^-4)). which is (111 * 20 * 10000)/2 = 11,100,000 cells per mL.
