Beta and Gamma Globulin Blood Test (Serum Protein Electrophoresis)

This test measures the amount of beta and gamma globulin proteins in the liquid part of your blood, called serum. It is usually done as part of a serum protein electrophoresis test, which separates blood proteins so your health care provider can see whether any of them are too high or too low. Abnormal levels may point to problems with your immune system, liver, kidneys, or bone marrow.

The beta and gamma globulin test is part of a procedure called serum protein electrophoresis (SPE). This test separates the different proteins in your blood based on their electrical charge. It specifically measures two types of proteins: beta globulins and gamma globulins.

Globulins are a group of proteins that circulate in your blood. Beta globulins include proteins that carry iron, fats, and other substances through your body. Gamma globulins are antibodies, also known as immunoglobulins, which are made by immune cells called plasma cells and help your body fight infections and other diseases.

Beta globulins are proteins that include transferrin (which carries iron in your blood), complement proteins (which help your immune system), and some antibodies. Gamma globulins are primarily immunoglobulins, also known as antibodies, which are essential for fighting infections and diseases. Both types of proteins are produced by your liver and immune system.

Your health care provider may order this test if you have symptoms that suggest abnormal protein levels. It can help diagnose or monitor conditions such as multiple myeloma and other plasma cell disorders, chronic infections, autoimmune diseases, liver disease, kidney disease, and nutritional deficiencies. It may also be used to check how well a treatment is working or to investigate unexplained symptoms such as fatigue, weakness, or frequent infections.

Your doctor may order this test if you have symptoms such as unexplained fatigue, frequent infections, bone pain, or abnormal protein levels found in routine blood tests. It helps doctors diagnose and monitor conditions affecting your immune system, liver, or bone marrow.

A health care professional will take a blood sample from a vein in your arm, usually on the inside of your elbow, using a small needle. You may feel a brief sting or pinch when the needle goes in. The sample is sent to a laboratory, where the proteins are separated and measured by a process called electrophoresis. The test itself takes only a few minutes.

A healthcare professional will draw a small sample of blood from a vein in your arm. The blood is collected in a tube and sent to a laboratory. In the lab, the sample is placed in a special gel and an electrical current is applied to separate the proteins. The amounts of beta and gamma globulins are then measured and recorded.

No special preparation is usually needed for this test. However, if your blood sample will also be used for other tests, you may be asked to fast for several hours beforehand. Tell your provider about all medicines, vitamins, and supplements you take, because some of them can affect your results. Wear a sleeve that can be rolled up easily to make the blood draw simpler.

This test usually does not require special preparation. You may be asked to fast (not eat or drink) for several hours before the test if other blood tests are being done at the same time. Follow any specific instructions given by your healthcare provider. Always inform your doctor about any medications or supplements you are taking.
