What is this test?
The Beta 2 Globulin test is a blood test that measures the level of beta 2 globulin proteins in your blood serum. This test uses a technique called electrophoresis, which separates different proteins in the blood based on their electrical charge. Beta 2 globulin is one of several protein fractions measured during this process, along with albumin, alpha 1, alpha 2, and beta 1 globulins.
Beta 2 globulin proteins are produced by the liver and play important roles in your immune system. They include certain transport proteins and components of the complement system, which helps your body fight infections. Measuring these proteins can provide valuable information about your overall health status.
Reference range
Reference values vary by laboratory; typically reported as a percentage of total protein or as absolute concentration. Beta-2 globulin fraction generally constitutes 2.2-5.0% of total serum protein (approximately 0.2-0.5 g/dL). Interpretation should be made in conjunction with the complete electrophoretic pattern.N/A
No special patient preparation is required. Fasting is not necessary for serum protein electrophoresis testing.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Elevated beta 2 globulin levels may indicate: chronic inflammatory diseases (such as rheumatoid arthritis or lupus), certain infections, liver disease, or some types of cancer. Decreased levels may be seen in malnutrition, kidney disease (nephrotic syndrome), or liver dysfunction.
The test is often ordered as part of a complete protein electrophoresis panel to help diagnose and monitor conditions affecting protein metabolism. Results are always interpreted in context with other protein fractions and clinical symptoms.
