High blood protein : When to see a doctor?

A total protein test can determine whether you have high blood protein. Other more-specific tests can help determine where it's coming from, for instance, the liver or the bone marrow. A serum protein electrophoresis (SPEP) test measures individual blood proteins. It can reveal which specific protein type is causing your high blood protein levels. Your doctor may use a SPEP if he or she suspects you have a bone marrow disease.
