Albumin/Globulin Ratio — What Your Blood Test Result Means

ScanHealth Learn Liver Function Albumin/Globulin Ratio

Liver vs Immune Balance

The A/G ratio compares your liver-made protein (albumin) to your immune-made proteins (globulins). In healthy people, albumin slightly outweighs globulin (ratio >1). When the ratio flips, it usually means your immune system is overactive or your liver is underperforming.

What is Albumin/Globulin Ratio?

A/G ratio = Albumin divided by Globulin. Normal is typically 1.0-2.5. Ratio <1.0 is clinically significant and warrants investigation into liver function and immune status.

What High Albumin/Globulin Ratio Means

More albumin relative to globulin. This is generally favorable and rarely concerning.

Common symptoms:

Generally not symptomatic

What Low Albumin/Globulin Ratio Means

Globulins are overtaking albumin. This suggests either your liver isn't making enough albumin (liver disease) or your immune system is making too many globulins (chronic infection, autoimmune, myeloma).

Common symptoms:

Combined symptoms of low albumin (edema) and high globulin (depends on cause)

Why It Matters

When normal:

Quick screen for liver vs immune disorders

Helps interpret total protein abnormalities

Monitors chronic liver disease progression

Risks if abnormal:

Low ratio: liver cirrhosis, autoimmune disease, chronic infection, myeloma

Very low ratio: advanced liver failure or aggressive immune disease

What Can Cause Abnormal Levels?

Chronic Liver Disease (low ratio)

50% likely

Reduced albumin production + increased globulin from immune activation in cirrhosis.

Chronic Immune Activation (low ratio)

45% likely

Autoimmune diseases or chronic infections increase globulin production.

Multiple Myeloma

Massive monoclonal globulin production dramatically lowers the ratio.

What You Can Do

Adequate protein nutrition to support albumin production

Impact: Raises numerator of ratio \u00B7 Timeline: 2-4 weeks

Anti-inflammatory diet to reduce immune overactivation

Impact: May lower globulin fraction \u00B7 Timeline: 4-8 weeks

If lifestyle changes aren't enough:

Treat underlying liver or immune condition

Impact: Addresses root cause of imbalance \u00B7 Timeline: Varies

Recommended retest: 4-8 weeks
