Serum or plasma concentration of total protein

Why Is This Test Done?

Doctors may order a total protein test to check for conditions like kidney disease, liver problems, malnutrition, or certain types of infections. It can also help diagnose or monitor conditions such as multiple myeloma, inflammatory diseases, or fluid imbalances in the body.

What Does the Test Involve?

A blood sample is taken from a vein, usually in your arm. The blood is then sent to a lab where it is analyzed to determine the total protein concentration. No special preparation is typically required, but you may be asked to avoid certain medications or foods for a short time before the test.

What Are Common Results and Their Meanings?

While specific reference ranges vary by lab, lower than expected protein levels might suggest malnutrition, kidney disease, or liver problems. Higher than expected levels could indicate conditions like multiple myeloma, severe dehydration, or certain inflammatory diseases. Your healthcare provider will interpret the results in the context of your overall health and medical history.

What Does This Test Tell Me About My Health?

Total protein levels can give clues about how well your kidneys are filtering waste and how your liver is producing proteins. Abnormal results may prompt further testing to identify underlying causes, such as specific blood tests or imaging studies.
