Formula used: A/G Ratio = Albumin ÷ (Total Protein - Albumin)

Calculation: 0 ÷ (0 - 0) = 0.00

Normal range: 1.2-2.2 (may vary by laboratory)

Clinical Significance

Example Calculation

Normal Adult Example

Albumin: 4.0 g/dL (normal range)

Total Protein: 7.0 g/dL (normal range)

Globulin: 7.0 - 4.0 = 3.0 g/dL

A/G Ratio Calculation

A/G Ratio = Albumin ÷ Globulin

A/G Ratio = 4.0 ÷ 3.0

A/G Ratio = 1.33 (Normal)

Blood Proteins Overview

A

Albumin

3.5-5.2 g/dL

Most abundant blood protein, maintains oncotic pressure

G

Globulin

2.6-3.5 g/dL

Includes antibodies and transport proteins

T

Total Protein

6.0-8.5 g/dL

Sum of albumin and globulin

A/G Ratio Ranges

1.2-2.2

Normal range (most common)

<1.0

Low - may indicate disease

>2.5

High - may indicate dehydration

Note: Reference ranges may vary between laboratories. Always consult your lab's specific ranges.

Understanding the Albumin Globulin Ratio

What is the A/G Ratio?

The albumin globulin ratio (A/G ratio) is a blood test that measures the ratio of albumin to globulin proteins in your blood serum. This ratio provides valuable information about liver function, kidney health, immune system status, and overall protein metabolism.

Clinical Uses

  • Assess liver function and protein synthesis
  • Evaluate kidney function and protein loss
  • Screen for inflammatory conditions
  • Monitor immune system disorders

Conditions Associated with Abnormal Ratios

Low A/G Ratio (<1.0)

  • • Liver disease (cirrhosis, hepatitis)
  • • Kidney disease (nephrotic syndrome)
  • • Autoimmune disorders
  • • Multiple myeloma
  • • Chronic inflammation

High A/G Ratio (>2.5)

  • • Dehydration
  • • Immunodeficiency disorders
  • • Leukemia
  • • Certain medications
