This page helps you to understand blood test results for Total Protein and gives you the reference range to determine if your lab test results mean that you have high, low or normal Total Protein levels.
We outline the risk factors associated with raised and low Total Protein levels.
Reference Ranges for Total Protein:
| Measurement Units | Metric | Optimal | Risk | |
|---|---|---|---|---|
| US Conventional Units | g/dl | 6-8 | < 6 or > 8 | |
| Standard International Units | g/l | 60-80 | <60 or >80 |
What is Total Protein
Total protein is the sum of the amount of Albumin and Globulin in the blood. Results of a total protein test are usually considered along with the other liver function test results as well as kidney and metabolic results. Results give information on a person’s general health status with regard to nutrition and/or conditions involving major organs, such as the kidney and liver. However, if results are abnormal, further testing is usually required to help diagnose the disease affecting protein levels in the blood [37].
Function of Total Protein
- A low total protein level can suggest a liver disorder, a kidney disorder, or a disorder in which protein is not digested or absorbed properly. Low levels may be seen in malnutrition and with conditions that cause malabsorption, such as celiac disease or inflammatory bowel disease (IBD).
- A high total protein level may be seen with chronic inflammation or infection [37].
Risk factors associated with Total Protein
Proteins have many different functions, including, helping you fight disease, regulating body functions, building muscles and transporting substances throughout the body [38].
Notable variations by Demographic Group
Low levels of total protein are more often seen in elderly patients [35].
