Total Protein with Albumin/GLOBulin Ratio (Serum)

What Does This Test Measure?

The test uses serum to separate proteins into three main categories: albumin, alpha-globulins, beta-globulins, and gamma-globulins. Albumin is the most abundant protein, supporting fluid balance and transport of substances. Globulins include proteins like immunoglobulins (antibodies) and other transport proteins. This separation helps identify imbalances that may indicate conditions such as liver disease, kidney problems, or immune system disorders.

Why Might You Need This Test?

Your healthcare provider may order this test if you have symptoms like unexplained weight loss, fatigue, swelling, frequent infections, or signs of organ dysfunction. It’s also used to monitor chronic conditions like liver disease, kidney disease, or certain cancers.

Sample Preparation and Collection

A blood sample is drawn from a vein, usually in your arm. The blood is then processed to separate serum (the liquid part after clotting) for testing. No special preparation is needed, but avoid eating or drinking for a few hours before the test if instructed.

What to Expect During the Test

The process is quick and typically painless. You may feel a slight pinch when the needle is inserted, but most people tolerate it well. The blood is then sent to a lab for analysis, which usually takes a few days to return results.
