Total Protein with Albumin-to-Globulin Ratio (serum/plasma)

Why Total Protein and Albumin-to-Globulin Ratio Matter

Total protein includes albumin and globulin proteins, which are vital for transporting nutrients, maintaining fluid balance, and supporting immune responses. Albumin is often the most abundant protein in blood, while globulins include proteins like antibodies and transport proteins. An abnormal ratio may signal conditions like malnutrition, liver disease, or immune disorders.

How the Test Works

Blood is drawn and processed to separate serum or plasma, where protein levels are measured using a specialized laboratory method. The albumin-to-globulin ratio is calculated by comparing the concentrations of these two protein types.

What the Results Typically Indicate

Low total protein or an elevated albumin-to-globulin ratio may suggest conditions like protein loss (e.g., kidney disease), malnutrition, or chronic inflammation. A low albumin level alone could indicate liver disease or poor nutritional intake, while high globulin levels might point to immune system overactivity or certain infections.

Common Conditions Monitored

Doctors may use this test to diagnose or monitor conditions such as liver disease, kidney disease, malnutrition, chronic infections, or autoimmune disorders. It can also help assess fluid balance and overall protein synthesis in patients undergoing certain treatments.
