3. What are globulin proteins and how are they measured in blood?
Globulins are all the proteins in the blood other than albumin, and this group is comprised of hundreds of different types. These proteins are larger than albumin and are divided into alpha, beta and gamma globulins.
Some globulin proteins can be measured directly using specific tests for the protein of interest. The tests are most valuable in instances where a specific protein is associated with a disease or condition. The specific protein tests may be ordered to provide information to the doctor when particular signs and symptoms are present that suggest one of these diseases or conditions. A few examples of proteins associated with specific conditions are C-reactive protein (inflammation), fibrinogen (clotting disorders), ferritin (iron deficiency), and ceruloplasmin (Wilson disease).
4. Can protein be measured in samples other than blood?
Yes, a test for protein can be performed on many different types of body fluids. The purpose for testing and the meaning of results vary. For more details, see the article on Body Fluid Analysis and click on the fluid of interest.
