Beta 2 Microglobulin Test Serum - Test for Beta 2 Microglobulin, Reasons Preparation and Procedure to Conuduct Beta 2 Microglobulin Test

Beta 2 Microglobulin Test

The term beta2 microglobulin effectively refers to a protein which you will find on the surface of countless cells. There are B2M tests involving Beta 2 microglobulin and serum, which may be undertaken for various reasons.

Reasons for Beta 2 Microglobulin Test

Usually it is undertaken when it comes to detecting some cancers, or when evaluating the same. Such cancers are typically those which target one’s white blood cells, like non-Hodgkin's lymphoma as well as chronic lymphocytic leukemia. Even in cases of kidney disease and in patients with multiple myeloma, this test may be prescribed. The levels of the protein beta 2 microglobulin in serum help the doctor better understand certain conditions. By serum we mean the part of blood which is both yellowish and liquidy in nature. In some cases, urine may be used for the Beta 2 microglobulin test instead of serum.

The reason this protein is thus employed is because Beta 2 microglobulin has a range of special characteristics on account of which it can be an effective tumor marker. With regards to its use in kidney disease and damage evaluation, it also is helpful when the doctor finds it necessary to determine whether it is glomerular or tubular disorders affecting the patient. At the same time, it must be said that B2M is not capable of giving an accurate diagnosis when it comes to pinpointing disease. However, it could not only point the health care practitioner in the right direction but it could also help determine the prognosis, which is most likely in the patient’s case. However, for the latter use, it is usually augmented by other tests.

Besides these uses, B2M tests also prove useful in kidney transplant patients, as a monitoring tool. This is not a common practice, but helps keep an eye on warning signs of kidney rejection. As a monitoring tool, it could help in cases where mercury in addition to other hazardous exposure like cadmium exposure is an occupational hazard.
 

Preparation for Beta 2 Microglobulin Test

Ask your doctor about Beta 2 microglobulin in serum testing preparation.

Procedure to Conduct Beta 2 Microglobulin Test

The B2M test is typically via blood or urine collection. In very rare cases of B2M testing, cerebrospinal fluid may be needed. Usually, the serum is taken and added to a substance or multiple substances so as to bind the protein. The amounts of beta 2 microglobulin in serum prove useful in aiding prognosis and in evaluation of various diseases.
