Understanding Albumin/Globulin Ratio: Normal vs Optimal Ranges

?What is Albumin/Globulin Ratio?

The albumin/globulin (A/G) ratio compares the two major protein fractions in the blood. Albumin, produced by the liver, is the dominant serum protein. Globulins include a diverse group of proteins involved in immune function and transport. A normal ratio reflects healthy liver synthetic function and balanced immune activity.

!Why It Matters

A reversed or low A/G ratio (below 1.0) can indicate liver disease, nephrotic syndrome, malnutrition, or chronic inflammation driving elevated globulins. A high ratio may suggest hypogammaglobulinaemia. The ratio helps distinguish the cause of abnormal total protein and guides further investigation.

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

• Oedema or ascites in severe hypoalbuminaemia
• Fatigue and weight loss from malnutrition or liver disease
• Recurrent infections with low globulins

How to Improve Your Levels

• 1Treat underlying liver disease
• 2Ensure adequate dietary protein intake
• 3Manage chronic inflammatory conditions
• 4Investigate and treat nephrotic syndrome if present

When to Test

Part of a comprehensive metabolic panel; useful when total protein is abnormal.
