Description
Estimated cost for Beta-2 microglobulin at general public hospitals in China is about ¥15-40, and at Grade 3A hospitals about ¥20-50, varying by hospital tier and region.
Main Uses
The primary purpose of the β2-microglobulin test is to assess kidney function, particularly in diagnosing and monitoring kidney diseases. It is also used to evaluate and monitor the progression of multiple myeloma, lymphomas, and other hematological malignancies. Additionally, it helps in assessing the effectiveness of treatments for these conditions.
Normal Range
The normal range for β2-microglobulin (β2M) in blood is typically between 0.8 to 2.4 mg/L, while in urine it is usually less than 300 μg/L over 24 hours. These values can slightly vary depending on the laboratory and the specific method used.
Low Values - Possible Causes
Low levels of β2-microglobulin are rare and not commonly reported. However, they may be associated with conditions such as immune deficiencies, certain types of leukemia, or severe liver disease. It's important to note that a low value is less clinically significant compared to high values.
High Values - Possible Causes
High levels of β2-microglobulin can indicate kidney dysfunction, multiple myeloma, lymphomas, HIV/AIDS, or other inflammatory conditions. Elevated levels might also be seen in patients undergoing dialysis or those with chronic infections.
