What is this test?
The Beta-2 Globulin and Total Protein test is a laboratory analysis that measures the levels of beta-2 globulin proteins and total protein in your blood serum using a technique called electrophoresis. Electrophoresis separates the different protein fractions in your blood based on their electrical charge, allowing doctors to identify and quantify each type, including beta-2 globulin.
Why is this test performed?
This test is performed to evaluate your overall health status and to help diagnose or monitor various conditions affecting your liver, kidneys, immune system, and nutritional status. Beta-2 globulin is a type of protein produced by the liver and plays important roles in immune function and transporting substances in the blood.
How is the test done?
A healthcare professional will draw a small blood sample from a vein in your arm. The blood is then sent to a laboratory where electrophoresis is used to separate and measure the different protein fractions, including beta-2 globulin and total protein levels.
Do I need to prepare for the test?
Generally, no special preparation is needed for this test. Your doctor may instruct you to fast for a certain period before the blood draw if other tests are being performed simultaneously. Always follow your healthcare provider's specific instructions.
Reference range
Beta-2 globulin typically represents 2.2-5.0% of total protein in serum. Reference values may vary by laboratory and specimen type (serum, urine, CSF, or other body fluid). Results are reported as a fraction or percentage of total protein.N/A
No special patient preparation is required. Fasting is not necessary for this test.
