Symptom: High blood protein

    High blood protein (hyperproteinemia) is an increase in the concentration of protein in the bloodstream. High blood protein is not a specific disease or condition in itself, but it might indicate you have a disease.

    High blood protein rarely causes signs or symptoms on its own. But sometimes it is uncovered while you're having blood tests done as part of an evaluation for some other problem or symptom.

    High blood protein
    1. Bone marrow disorder
    2. Multiple myeloma
    3. Amyloidosis
    4. Monoclonal gammopathy of undetermined significance
    5. Chronic inflammatory conditions
    6. HIV/AIDS
    7. Dehydration (which may make blood proteins appear falsely elevated)

    A high-protein diet doesn't cause high blood protein.

    High blood protein is not a specific disease or condition in itself. It's usually a laboratory finding uncovered during the evaluation of a particular condition or symptom. For instance, although high blood protein is found in people who are dehydrated, the real problem is that the blood plasma is actually more concentrated.

    Certain proteins in the blood may be elevated as your body fights an infection or some other inflammation. People with certain bone marrow diseases, such as multiple myeloma, may have high blood protein levels before they show any other symptoms.

    Proteins are large, complicated molecules that are vital to the function of all cells and tissues. They are made in many places throughout your body and circulate in the blood.

    Proteins take a variety of forms — such as albumin, antibodies and enzymes — and have many different functions, including:

    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.
