What this marker measures
Globulin is often a calculated value (total protein minus albumin). The fraction breakdown — alpha, beta, gamma — requires a separate test called protein electrophoresis when more detail is needed.
High or low: what it can mean
High Globulin
Elevated globulin can be seen with chronic inflammation, infection, certain liver conditions, or higher immunoglobulin production. It is interpreted alongside the rest of the protein panel and the broader clinical picture — diagnosis usually requires confirmation and clinical context.

Low Globulin
Low globulin may be seen with reduced immunoglobulin production or protein loss. It is interpreted together with albumin, total protein, and the wider picture.

Frequently asked questions
What is Globulin?
+
Globulin is a group of blood proteins (alpha, beta, and gamma fractions, including immunoglobulins). It is often reviewed together with albumin, total protein, and the A/G ratio.
