The protein is produced by a group of cells in the bone marrow called plasma cells. Plasma cells are normally found in the bone marrow and represent approximately one percent of all marrow cells. They produce the antibodies that help your body fight infection. Abnormal proteins circulating in the blood are not rare. They occur in one percent of healthy people over the age of 50 and in three percent of people over the age of 70.
Monoclonal gammopathy occurs in both sexes and in people of all backgrounds and occupations.
Generally, the abnormal protein in the blood produces no symptoms. Most monoclonal gammopathies are detected as part of a complete physical examination. In your situation, detecting the abnormal protein is of no great concern now. Discuss with your physician the need for follow-up. A test called serum protein electrophoresis was performed on your blood.
