- Elevated levels can sometimes indicate problems in the central nervous system.
Key Takeaways
- IgG is an antibody, meaning it helps fight infections.
- IgG can be measured in bodily fluids like CSF.
- A CSF IgG index is a medical test that looks at the quantity of IgG in the Cerebrospinal Fluid.
- It is a protein produced by the body to fight germs.
