Albumin/Globulin Ratio

The albumin/globulin (A/G) ratio compares the levels of albumin and globulin proteins in your blood. This ratio helps evaluate liver function, kidney function, and immune system health.

Category: Metabolic Panel

Also known as: a/g ratio, albumin/globulin ratio, ag ratio, albumin globulin ratio, odnos albumin/globulin

Reference range: 1.1–2.5 ratio (Source: ABIM)

Standard unit: ratio

High values may indicate

A high A/G ratio is generally not clinically significant but may indicate underproduction of globulins, as seen in some genetic conditions or immune deficiencies.

Low values may indicate

A low A/G ratio may indicate liver disease, kidney disease, autoimmune conditions, or multiple myeloma.

Frequently asked questions

What is a normal Albumin/Globulin Ratio level?
A typical reference range for Albumin/Globulin Ratio is 1.1–2.5 ratio (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
What units is Albumin/Globulin Ratio measured in?
Albumin/Globulin Ratio is most commonly reported in ratio. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
Where do Albumin/Globulin Ratio reference ranges come from?
BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
Can I track Albumin/Globulin Ratio over time?
Yes. Upload results from any lab and BloodId charts your Albumin/Globulin Ratio over time against its reference range, so you can see whether the trend is rising, falling, or stable.
