Usually calculated as total protein minus albumin; reflects antibody and other globulin proteins.
What it is
Globulin is often a calculated line on liver/protein panels. It groups many proteins including immunoglobulins.
Why it matters
High or low globulin prompts review of inflammation, liver disease, immune issues, or lab calculation quirks, not a diagnosis by itself.
This guide is educational only and cannot diagnose you. Discuss results, especially anything outside your laboratory’s reference interval, or that does not match how you feel, with a GP or other appropriately qualified clinician.
How it affects the body
Globulins include transport proteins and antibodies that shape immune defence and inflammation.
For athletes
Transient shifts after illness are common; persistent unexplained changes need medical advice.
