1. What is an Albumin/Globulin (A/G) Ratio?
The albumin/globulin (A/G) ratio is a calculation derived from the results of a comprehensive metabolic panel (CMP) or a protein electrophoresis test. It compares the amount of albumin, a specific protein, in your blood to the amount of globulins, another group of proteins. Albumin and globulins perform several vital functions in the body. This ratio helps healthcare professionals assess overall health and screen for potential medical conditions.
Key Functions of Albumin:
- Maintains fluid balance in the blood vessels.
- Transports hormones, vitamins, and other substances throughout the body.
- Synthesized in the liver.
Key Functions of Globulins:
- Part of the immune system, fighting infections.
- Transports nutrients.
- Some are made in the liver, others by the immune system.
2. Why is the A/G Ratio Important?
The A/G ratio provides valuable information about the balance of these two protein types in your blood. Deviations from the normal range can indicate a variety of health issues, including liver disease, kidney disorders, malnutrition, and immune system abnormalities.
3. What Does the A/G Ratio Test Measure?
The A/G ratio test measures the proportion of albumin to globulin in your blood. A healthy A/G ratio indicates a proper balance between these two essential protein groups, reflecting normal liver function, kidney function, and immune system activity. The test doesn’t directly measure specific diseases but serves as an indicator of underlying health conditions.
