What is considered a high beta-2 microglobulin?

What is considered a high beta-2 microglobulin?

The amount of beta-2-microglobulin in the blood….The Revised International Staging System.

RISS Stage Group	Factors
III	Serum beta-2 microglobulin is 5.5 (mg/L) or greater AND Cytogenetics are considered “high-risk”* AND/OR LDH levels are high

What is a beta-2 microglobulin serum test?

This beta-2 microglobulin (B2M) test is used as a tumor marker for some people with blood cell cancers. It is not diagnostic for a specific disease, but it has been associated with the amount of cancer present (tumor burden) and can give a healthcare practitioner additional information about someone’s likely prognosis.

Is beta-2 microglobulin the same as beta globulin?

Beta globulins are a group of globular proteins in plasma that are more mobile in alkaline or electrically charged solutions than gamma globulins, but less mobile than alpha globulins. Examples of beta globulins include: beta-2 microglobulin.

What is beta-2 microglobulin amyloidosis?

Beta-2 ̶ microglobulin (beta-2m) amyloidosis is a disabling condition that affects patients undergoing long-term hemodialysis (HD) or continuous ambulatory peritoneal dialysis (CAPD). Case reports involving patients with near ̶ end-stage renal disease also exist.

What causes high beta-2 microglobulin?

Conditions associated with an increased rate of cell production or destruction, severe infections, viral infections such as CMV (cytomegalovirus), and some conditions that activate the immune system, such as inflammatory conditions and autoimmune disorders, can cause increases in beta-2 microglobulin levels, but the …

What are the symptoms of Stage 2 multiple myeloma?

Stage 2. Classification of stage 2 multiple myeloma occurs with test results that are between the levels expected for stage 1 and stage 3. Stage 2 indicates the progression of the cancer. A person may start to experience symptoms, such as bone pain, loss of appetite, and fatigue.

What are the three stages of multiple myeloma?

In this system, there are three stages of myeloma: Stage I, Stage II, and Stage III. The stage depends on factors including: The amount of myeloma cells in the body. The amount of damage the myeloma cells have caused to the bone.

What does an elevated beta globulin mean?

Elevated beta-globulin levels may be indicative of chronic liver or kidney disease, or chronic inflammatory diseases such as aspergillosis or avian chlamydiosis. The most common reason for elevated beta globulins in birds, which is attributable to the transferrin component, is egg production.

What causes high beta globulin?

What is the normal beta 2 microglobulin level?

Beta 2 microglobulin normal range 1 Beta 2 microglobulin in urine normal range: < or =300 mcg/L 2 Beta 2 microglobulin in serum normal range: 1.21-2.70 mcg/mL 3 Beta 2 microglobulin in cerebrospinal fluid (CSF) normal range: 0.70-1.80 mcg/mL

What is the normal range for beta 2?

The normal range for Beta 2 micro globulin in a test is extremely low. If there is no detection in a urine test, it is assumed that the level of Beta 2 micro globulin is within the safe range.

How is beta 2 microglobulin ( B2M ) used as a tumor marker?

This test measures the amount of a protein called beta-2 microglobulin (B2M) in the blood, urine, or cerebrospinal fluid (CSF). B2M is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body. B2M is found on the surface of many cells and is released into the body.

How does Beta 2 microglobulin affect the staging system?

The staging system is based mainly off of levels of both albumin and beta 2 microglobulin in the blood. Higher blood beta 2 microglobulin levels correspond with higher disease stages and therefore more advanced disease with worse prognosis. What are tumor markers?
