Total protein test

Find out about the health conditions a total protein test can help diagnose. If your total protein level is too high or too low, you'll need further tests to identify the specific proteins.

A total protein test measures the amount of protein in your blood.

Proteins are important for the health and growth of the body's cells and tissues.

The test can help diagnose a number of health conditions, including:

If your total protein level is low, you may have a liver or kidney problem, or it may be that protein isn't being digested or absorbed properly.

A high total protein level could indicate dehydration ↗ or a certain type of cancer ↗, such as multiple myeloma ↗, that causes protein to accumulate abnormally.

If the result of a total protein test is abnormal, further tests will be needed to identify which proteins are too high or too low. This will enable an accurate diagnosis to be made.
