Beta 2 Microglobulin (B2M) Tumor Marker Test

What is Beta 2 Microglobulin (B2M) Tumor Marker Test?

Beta 2 Microglobulin (B2M), also known as β2 Microglobulin or Beta-2-Microglobulin, is a protein encoded by the B2M gene that plays an important role in the immune system. It is also known as a marker for cancer, as it can be used to detect the presence of certain types of cancer, such as lymphoma and leukemia. It can also be used to monitor the response to cancer therapy. The B2M tumor marker test measures the concentration of B2M in a patient's blood or urine sample to detect the presence of cancer.

Preparation for Beta 2 Microglobulin (B2M) Tumor Marker Test

There is no special preparation required for the B2M tumor marker test. However, it is important to inform your doctor of all medications, including vitamins and supplements, that you are taking, as these may interfere with the results of the test.

Procedure for Beta 2 Microglobulin (B2M) Tumor Marker Test

The B2M tumor marker test is conducted by taking a blood or urine sample from the patient. The sample is then sent to a laboratory for analysis. The laboratory measures the concentration of B2M in the sample, which is then compared to a reference range. An elevated B2M concentration could indicate the presence of a tumor.

Types of Beta 2 Microglobulin (B2M) Tumor Marker Test

The B2M tumor marker test is typically conducted as part of a biochemical panel that includes tests for other tumor markers, such as CA-125, CEA, and AFP. It can also be conducted as a stand-alone test.

Risks of Beta 2 Microglobulin (B2M) Tumor Marker Test

The B2M tumor marker test is a relatively safe procedure, as it does not involve any radiation. There is very little risk associated with the procedure, unless the person taking the test is on blood-thinning medications, as these can produce inaccurate results.

Why is Beta 2 Microglobulin (B2M) Tumor Marker Test necessary?

The B2M tumor marker test is used to detect the presence of cancer. It is especially useful in detecting lymphoma and leukemia, as it is often elevated in these cases. In addition, it can be used to monitor the response to cancer treatment, as it is often reduced over time.

When to Perform Beta 2 Microglobulin (B2M) Tumor Marker Test?

The B2M tumor marker test is usually conducted when cancer is suspected, in order to confirm the diagnosis. It can also be used to monitor the response to cancer treatment. In addition, the test may be performed if the patient experiences certain symptoms, such as unexplained weight loss, fatigue, or fever. The test is not recommended for routine screening for cancer.
