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.
