Beta 2 (B2) Microglobulin Blood Test (Labcorp)
This test measures the level of Beta-2 Microglobulin in the blood. B2 Microglobulin is a protein found on the surface of many types of cells in the body. Blood levels of B2 are normally low as it is mostly filtered out by the kidneys. When kidney function is impaired, B2 levels often rise. Measuring B2 levels in people with kidney disease can help evaluate how severe their disorder is and if they are responding to treatment.
Elevated B2 levels are also associated with certain types of cancers such as Multiple Myeloma and Lymphoma. Other conditions such as HIV or Cytomegalovirus may also increase B2-Microglobulin levels. B2 is sometimes used as a tumor marker. While it is not used as a screening, measuring B2 levels can help assess the severity of a person's cancer. It is also used in some cases to measure how effective someone's treatment has been.
B2-Microglobulin testing is typically ordered when someone has symptoms of kidney dysfunction or to monitor treatment for kidney failure. It may also be ordered after a person has been diagnosed with cancer such as Multiple Myeloma to determine what stage of the disease they are in.
Turnaround for this test is typically 3-5 business days.
