Total Protein with Albumin-to-Globulin Ratio (Serum)

Why This Test Matters

Total protein in your bloodstream is made up of albumin and globulin proteins, both of which play key roles in maintaining fluid balance, transporting nutrients, and supporting immunity. Albumin, produced by your liver, helps keep fluids in your blood vessels, while globulins assist with immune function and transporting substances like iron and hormones. An imbalance between these proteins can signal underlying health issues.

How the Test Works

Your blood sample is analyzed to measure total protein content and separately assesses albumin and globulin levels. The albumin-to-globulin ratio is then calculated to compare their proportions. This ratio can be affected by conditions like liver disease, chronic inflammation, or malnutrition.

Common Conditions Monitored

This test is often used to diagnose or monitor conditions such as liver cirrhosis, chronic kidney disease, malnutrition, or autoimmune disorders. Low albumin levels may indicate liver or kidney problems, while elevated globulins could suggest chronic infections or inflammatory conditions.

What to Expect Before the Test

No special preparation is needed for this test. You may have a small needle inserted into your arm to draw blood, similar to other routine blood tests. If you’re on certain medications, let your healthcare provider know before the test.
