. The fluid is first tested for pressure; a high reading may signal inflammation or tumor. If pressure is normal, a small sample can be taken. It is then analyzed for antibodies, white blood cells, cellular debris, bacteria, and other organisms. Unusual concentrations may indicate disorders such as spinal meningitis, polio, or cancer. The concentrations of protein, sugar, and other chemical components are also determined. Excessive protein may be a sign of spinal tuberculosis.
