Overview

The Albumin-Globulin (A/G) ratio is a laboratory metric derived from a total protein test. It compares the amount of albumin to the amount of globulins (all other proteins) in the blood. Significant changes in this ratio can indicate liver disease, kidney disease, or inflammation.

💡

Pro Tips

Ensure units are consistent (usually g/dL) for both measurements.
A high ratio might be seen in leukemia or some genetic deficiency of globulin production.
The ratio is a screening tool; abnormal results require investigation of specific protein fractions.

Fun Facts

"A normal A/G ratio is typically between 1.1 and 2.5."
"Albumin is produced by the liver and accounts for about 60% of total protein."
"Globulins include antibodies (gamma globulins) and transport proteins (alpha/beta globulins)."
"A low ratio can be caused by liver cirrhosis, nephrotic syndrome, or multiple myeloma."

Formula: Globulin = Total Protein - Albumin. A/G Ratio = Albumin / Globulin.
