The non-albumin protein fraction — includes immunoglobulins and carrier proteins.
What is it
Globulins include immunoglobulins (antibodies) and various carrier proteins. Globulin is calculated by subtracting albumin from total protein.
Why it's measured
Globulin levels have been studied in research on chronic inflammation, infection, and certain immunologic conditions.
Reference range
Standard laboratory reference
2.0 – 3.9 g/dL
