A total protein test is frequently ordered as part of a comprehensive metabolic panel (CMP) when an individual undergoes a routine health checkup. Total protein may also be ordered to provide general information about a person’s nutritional status, such as when someone has undergone a recent, unexplained weight loss. It can be ordered along with several other tests to provide information when someone has symptoms that suggest a liver, kidney, or bone marrow disorder, or to investigate the cause of abnormal pooling of fluid in tissue (edema).
This test will also look at the ratio of albumin to globulin in your blood. This is known as the “A/G ratio.”
The normal range for total protein is between 6 and 8.3 grams per deciliter (g/dL). This range may vary slightly among laboratories. These ranges are also due to other factors such as:

Your total protein measurement may increase during pregnancy.
