Understanding Globulin: Normal vs Optimal Ranges

?What is Globulin?

Globulins are a group of proteins in the blood that include immunoglobulins (antibodies), transport proteins, and clotting factors. They are produced by the immune system and the liver. Total globulin is calculated as Total Protein minus Albumin.

!Why It Matters

Elevated globulin (hyperglobulinaemia) may indicate chronic infection, autoimmune disease, or liver cirrhosis. Very high globulin (>4.5 g/dL) may suggest multiple myeloma or other paraproteinaemias, which requires further investigation with protein electrophoresis. Low globulin may indicate immune deficiency.

Reference Ranges

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.

Symptoms of Imbalance

• Elevated: fatigue, frequent infections, bone pain in myeloma
• Low: increased infection susceptibility

How to Improve Your Levels

• 1Treat underlying infection or inflammation
• 2Specialist evaluation for significant elevations
