What are normal ranges for CSF?
Normal Results CSF total protein: 15 to 60 mg/100 mL. Gamma globulin: 3% to 12% of the total protein. CSF glucose: 50 to 80 mg/100 mL (or greater than two thirds of blood sugar level) CSF cell count: 0 to 5 white blood cells (all mononuclear), and no red blood cells.
What is the normal glucose mmol L level in a CSF?
Normal levels of glucose in the CSF are greater than 50 mg/dL to 80 mg/dL, or 2.8 mmol/L to 4.4 mmol/L. If your levels are lower, you may have an infection. Your healthcare provider will look at your CSF glucose level along with the other CSF tests, and possibly other tests, to better understand what your results mean.
What are the characteristics of normal CSF?
Color of the fluid—normal is clear and colorless. Changes in the color of the CSF are not diagnostic but may point to additional substances in the fluid. Yellow, orange, or pink CSF may indicate the breakdown of blood cells due to bleeding into the CSF or the presence of bilirubin.
Why is glucose low in CSF in meningitis?
The reason for the reduced glucose levels associated with bacterial meningitis was believed to be the need for glucose as fuel by infiltrating immune cells in response to infection. However, the possibility that the bacteria itself could manipulate glucose concentrations in the brain had not been explored before now.
What do my CSF results mean?
What do the results mean? Your CSF analysis results may indicate that you have an infection, an autoimmune disorder, such as multiple sclerosis, or another disease of the brain or spinal cord. Your provider will likely order more tests to confirm your diagnosis.
How do you interpret CSF IgG?
Cerebrospinal fluid (CSF) IgG synthesis rate indicates the rate of increase in the daily CSF production of IgG in milligrams per day. A result greater than 12 mg/24 hours is elevated. A CSF index greater than 0.85 is elevated and indicative of increased synthesis of IgG.
