What Does Total Protein Measure?

Total protein includes albumin and globulin, which are produced by your liver and immune system, respectively. Albumin helps keep fluids in your bloodstream, while globulins assist with immune responses and blood clotting. Together, they reflect overall protein health.

Why Is the Albumin-to-Globulin Ratio Important?

The ratio compares albumin (a protein that helps prevent fluid leakage) to globulin (proteins involved in immunity and clotting). A higher albumin-to-globulin ratio often suggests healthy protein balance, while an imbalance may indicate conditions like liver disease, malnutrition, or chronic inflammation.

How Is This Test Performed?

A small blood sample is drawn from your arm, and the serum (liquid part after clotting) is analyzed to measure total protein and the albumin-to-globulin ratio using standard laboratory techniques.

When Might You Need This Test?

Your doctor may order this test if you have symptoms like swelling, unexplained weight loss, fatigue, or signs of liver/kidney issues. It’s also used in routine health checks or to monitor chronic conditions.

Frequently asked questions

What causes low total protein levels?
Low total protein can result from conditions like liver disease (reducing albumin production), kidney disease (losing protein in urine), malnutrition, or severe infections. It may also occur due to overhydration or certain medications.
How long does it take to get results?
Results are typically available within 1–3 business days, depending on your lab’s processing time. Your doctor will discuss findings with you during your follow-up visit.
Can diet affect this test?
Yes, certain foods high in protein (like lean meats, eggs, or dairy) may influence results. Avoiding excessive alcohol or high-protein supplements for a few days before testing can help ensure accurate results.
