A total protein blood test measures the total amount of protein in the fluid portion of your blood. The two main types of proteins measured are albumin and globulin. Proteins are essential for the health and growth of the body's cells and tissues. Albumin helps prevent fluid from leaking out of blood vessels and also carries chemicals in your blood.
Why is a total protein test done?
This test can be used to diagnose and monitor a variety of conditions, including:
- Kidney disease: Low protein levels can indicate kidney problems.
- Liver disease: Low protein levels can indicate liver problems.
- Malnutrition: Low protein levels can indicate malnutrition.
- Inflammation or infection: High protein levels can indicate inflammation or infection.
- Certain types of cancer: High protein levels can indicate certain types of cancer.
How is the test done?
A blood sample is taken from a vein, usually in your arm. The blood is then analyzed in a laboratory to determine the total protein level.
What are normal total protein levels?
Normal total protein levels vary depending on age, sex, and other factors. Your doctor can tell you what a normal range is for you.
What do the results mean?
- High total protein levels can indicate inflammation, infection, or certain types of cancer.
- Low total protein levels can indicate kidney disease, liver disease, malnutrition, or other conditions.
It's important to note that this test alone cannot diagnose any specific condition. Your doctor will need to consider your other symptoms and medical history to make a diagnosis.
