Beta-2 microglobulin is a blood, urine or cerebrospinal fluid test to help stage a disease (an elevated B2M may indicate metastasis) and monitor treatment response.
In the healthy kidney, β 2 MG passes through the glomeruli, and is then almost completely reabsorbed by the proximal tubules. 1 In someone with signs of kidney disease, measurement . Alternative name. β2M. Description. β-2 microglobulin is a small lymphoid cell surface protein protein. Serum concentrations can be used as an index of cellular turnover and renal function sdince it is rapidly excreted through a healthy kidney. β-2 microglobulin is a useful prognostic marker in myeloma but also raised in Sjogrens syndrome, HIV related disease and . This test detects and measures one or more classes (IgG, IgM, or very rarely IgA) of beta-2 glycoprotein 1 antibodies.Beta-2 glycoprotein 1 antibody is a protein c-factro that binds to phospholipids.Phospholipids are lipid-proteins found in the outermost layer of cells (cell membrane) including blood cells such as platelets.This test measures the amount of beta-2-microglobulin in blood. It may be used to evaluate and manage renal (kidney) failure, bone marrow tumors (multiple myeloma), other types of cancer, or abnormal growths[1][2].
beta 2 microglobulin test results
The test measures the amount of beta-2 microglobulin in a sample of blood. Beta-2 microglobulin is a protein that is produced by many types of cells in the body, including immune cells and certain cancer cells. Increased levels of beta-2 microglobulin in the blood may indicate the presence of a tumor or indicate the progression of certain cancers.

Adults: 0.8 - 2.2 mg/L - New range as of 03/04/18 (Quoted by manufacturer) Limitations: Raised levels of beta 2 microglobulin may be observed in any condition where there is increased cell turnover or immune activity e.g. CMV and HIV infection, inflammatory and autoimmune disorders. NotesSchematic representation of MHC class I. β 2 microglobulin lies beside the α 3 chain on the cell surface. Unlike α 3, β 2 has no transmembrane region. Directly above β 2 (that is, further away from the cell) lies the α 1 chain, which itself is next to the α 2.. β 2 microglobulin associates not only with the alpha chain of MHC class I molecules, but also with class I-like molecules such .
The beta-2 microglobulin (B2M) test may be used in rare circumstances when kidney damage has occurred to distinguish between the two most commonly affected sites, glomeruli and tubules.It does not replace front-line kidney function tests such as urea, creatinine, and microalbumin.B2M is also non-specific in that it will increase with disorders that involve .β-2-MICROGLOBULIN OSR6151 4 x 10 mL R1 .

Other times your symptoms may lead your health care professional to test for multiple myeloma. Tests and procedures to diagnose multiple myeloma include: Blood tests. The M proteins made by myeloma cells can show up in a sample of blood. Blood tests also might find another protein myeloma cells make, called beta-2-microglobulin.Beta 2 Microglobulin (Blood) Alternate Names. B2 Microglobulin, B2M, B2MG. Test Code. B2M.

In a study of pretreatment serum beta-2-M levels in 100 patients with myeloma, it was reported that the median survival of patients with values greater than 4 mcg/mL was 12 months, whereas median survival for patients with values less than 4 .
The beta-2 microglobulin blood test is not a routine test. If your doctor has asked for it is because he wants to evaluate a possible cancer or a kidney disease. In case of suffering from multiple myeloma, values can reach to 90 o 100 mg/l in the blood. The higher they are, the worse is the prognosis of the disease. .These scoring systems get information from blood tests. The tests measure levels of beta 2 microglobulin (β2M), albumin, and lactate dehydrogenase. To stage multiple myeloma, we use genetic tests to look at certain chromosomes to see if they’re normal. We measure your levels of: Beta 2 microglobulin (BAY-tuh-2-MY-kroh-GLAH-byoo-lin). It’s .Laboratory Test Guide. Search. . Beta 2 Microglobulin, Serum. Lab Code. BETA2. Epic Name.

Beta-2-Microglobulin, Serum - Beta-2-microglobulin normally passes through the glomerulus into the proximal tubule where much of it is reabsorbed. Serum levels are therefore an index of glomerular function. When impaired, serum levels rise in inverse ratio to glomerular filtration rate. Increased amounts of beta-2-microglobulin are excreted in several renal disorders, e.g., .Lab Test: Beta-2 Microglobulin Quick Launch. Rush Medical Labs. Staff Directory; Testing Information.

Labcorp test details for β2-Microglobulin. β-2 microglobulin (β 2 MG) is a small membrane protein that is a component of the class I major histocompatibility complex found on the surface of all nucleated cells. 1 β 2 MG is especially abundant on the surface of white blood cells so increased production or destruction of these cells causes serum levels to increase. 1 Levels of .Because Beta-2 Microglobulin is increased with blood cell cancers, it may be useful as a tumor marker. Though it can be used to assess kidney function as well.

Also known as: BMG β2-microglobulin is an 11 KDa protein found on the surface of all nucleated human cells as a component polypeptide chain of the HLA Class I antigen complex.It is excreted via the renal glomerulus, the majority being reabsorbed in the proximal tubules. It exists in the serum as a stable monomer with no significant diurnal variation and is used to monitor B cell .Synonyms: β2-Microglobulin, B2M . Background: Beta-2 microglobulin is found on the surface of almost all cells in the body and is shed by cells into the blood, particularly by B-lymphocytes and tumour cells. Concentrations in the bloodstream rise with conditions that increase cell production and/or destruction, or that activate the immune system. Beta-2 microglobulin (B2m) is the 11.8 kDa light-chain moiety of major histocompatibility complex class I (MHC I) present on the surface of nearly all nucleated cells .
