The normal value of beta-2 microglobulin is less than 2 mg/L. The test is used as a tumor marker for some blood cell cancers. Some severe infections, viral infections, inflammatory conditions, and autoimmune disorders can elevate this level.
structure
Beta2-microglobulin is a protein found on the surface of many cells. Testing is done primarily when evaluating a person for certain kinds of cancer affecting white blood cells.
Serum: less than or equ to 2.7 g/ml . Urine: less than 1 mg 24 hours 0-160 g/L
Serum: less than or equ to 2.7 g/ml . Urine: less than 1 mg 24 hours 0-160 g/L
excessive urine production and urination; excessive thirst; dehydration; constipation; anorexia nervosa; vomiting; elevated levels of glucose, phosphate, calcium, uric acid, amino acids, and protein (especially beta2-microglobulin.

Testing is done primarily when evaluating a person for certain kinds of cancer affecting white blood cells including chronic lymphocytic leukemia, non-Hodgkin's lymphoma, and multiple myeloma or kidney disease.
The blood test requires 5 mL of blood.Urine may be a single collection or collected throughout a 24-hour time period. The urine should be refrigerated until it is brought to the laboratory and must not become acidic.
Discomfort or bruising may occur at the puncture site or the person may feel dizzy or faint. Pressure to the puncture site until the bleeding stops reduces bruising. Warm packs on the puncture site relieve discomfort.
The meaning of an abnormal result varies with the clinical condition of the person tested.with multiple myeloma, a higher level means a poorer prognosis than a lower level.with kidney disease, an increased blood level means the problem is tubular.
Beta1 and beta2 are different types of adrenergic receptors found in the body. Beta1 receptors are primarily located in the heart and play a role in regulating heart rate and contractility. Beta2 receptors are found in the lungs, blood vessels, and other tissues, and are involved in processes such as smooth muscle relaxation and bronchodilation.
There are three types of bronchodilators: Beta2 agonists, anticholinergic agents, and theophylline and its derivatives
