What is a Total Protein Test?
The Total Protein Test, also known as total serum protein, is a measure of total protein in the blood. There are two main types of protein in the blood, namely:
- Albumin: This protein stops the blood from leaking out of blood vessels. It helps in the circulation of hormones, medicines, vitamins, and other vital substances within the body.
- Globulin: It protects the body against infection and helps in the transportation of nutrients in the body.
A constant ratio exists between these proteins in the blood. Any alteration of this ratio indicates underlying pathological conditions such as kidney problems and liver malfunction. This test measures the ratio between the two called the albumin/globulin ratio.
