What is Serum Globulin (Globulin)?

Serum Globulin is measured as part of a liver function panel. Your globulin is in a healthy range — your antibody and transport proteins are balanced.

What does a high Serum Globulin mean?

Your globulin is elevated, which can occur with chronic infection, inflammation, liver disease, or immune conditions.

What does a low Serum Globulin mean?

Your globulin is low, which can occur with certain immune or kidney conditions. It's usually interpreted alongside your albumin.
