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("bloody tap") can result in RBCs being present in the CSF, the blood will progressively clear with each tube of CSF withdrawn.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.
WebComparison with cell counts obtained with a hemocytometer showed good correlation (>97%) between the GloCyte and the hemocytometer, including at very low cell counts.
