Albumin Globulin Ratio Calculator
Calculate A/G ratio to assess protein balance and diagnose various medical conditions
Calculate A/G Ratio
Normal range: 3.5-5.2 g/dL
Normal range: 6.0-8.5 g/dL
A/G Ratio Results
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
Albumin
3.5-5.2 g/dL
Most abundant blood protein, maintains oncotic pressure
Globulin
2.6-3.5 g/dL
Includes antibodies and transport proteins
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
