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

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

  • kidney disease
  • liver disease
  • malnutrition – where a person's diet doesn't contain enough nutrients to meet their body's needs

If your total protein level is low, you may have a liver or kidney disorder, or a disorder where protein isn't 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.
