clinical definition of
Beta-2 Microglobulin is a protein that is present on the surface of most cells. Its levels can rise in the blood because of conditions that increases the cell production, cause destruction of cells, or activate the immune system. The protein itself causes no harm, but is an indicator for making prognosis.
Increased levels of Beta-2 Microglobulin are useful markers in diagnosing tumors, as Beta-2 Microglobulin levels can get elevated in the blood due to cancers, such as lymphoma and multiple myeloma.
when do you expect results?
24 to 36 Hours
why get tested?
The test detects the level of the protein, Beta-2 Microglobulin, in the blood. The test, like most other tests, is not done for the purpose of diagnosis, but for prognosis, and to find the severity of cancer in the patient. An increased level of Beta-2 Microglobulin indicates the presence of a problem, but the test will not help diagnose the specific condition or the disease. It will however, indicate the severity of cancer present and how advanced it is.
reason to take test
This test is ordered when the patient has been diagnosed with myeloma, as it helps stage the disease and to evaluate the effectiveness of the treatment that the patient might already be undergoing. The test also helps the doctor in making a prognosis and to decide on the future course of action.
The test may be ordered in conjugation with a urine test, and in rare cases, Cerebrospinal Fluid (CSF) may also be collected.

The test requires no prior preparation and can be done at any time of the day. Just to remain on the safe side, please inform your doctor of any medications you are on, or if you suffer from any allergies. Accordingly, your doctor may provide specific instructions.
Specimen type: Serum (Blood Sample) How is the specimen collected: Through venipuncture collection of blood from a vein within the arm
