High blood protein levels rarely cause symptoms, according to Mayo Clinic. However, a high blood protein level might be a symptom itself of a disease or condition, and doctors can order further tests to determine the cause of the elevated blood protein level.
Blood marrow disorders, multiple myeloma and HIV/AIDS can cause high blood protein levels, explains Mayo Clinic. Dehydration can cause blood protein levels to rise as well, and patients might experience elevated counts as their bodies fight infections and react to inflammation. Other potential causes are chronic inflammatory conditions.
The human body uses proteins for a variety of tasks, reports Mayo Clinic. Protein helps the body fight disease, and it plays a role in building muscles. Protein transports substances through the body, including drugs in some cases, and it helps regulate various body functions. Albumin is a protein, as are antibodies and enzymes.
Standard blood tests that include protein tests typically only check the overall level of protein in the blood; they don't look at specific types of protein. Because of this, doctors might order serum protein electrophoresis tests to examine the levels of different types of blood proteins. This information can help a doctor make a diagnosis if she suspects a patient has a bone marrow disease, notes Mayo Clinic.
