Description
The urinary β2-microglobulin test assesses early kidney tubular damage—often needed for monitoring diabetes, hypertension, or autoimmune disease—and costs ¥7–30 at partner hospitals in China, with ChinaMedicalHub assisting with booking and interpreter support.
Main Uses
Urinary β2-microglobulin testing is primarily used to assess kidney function, particularly to detect early signs of renal tubular damage. It is also useful in monitoring the progression of kidney diseases, evaluating the effectiveness of treatments, and diagnosing conditions that affect the kidneys' ability to filter waste from the blood.
Normal Range
The normal range for urinary β2-microglobulin (β2-MG) is typically between 0.1 to 0.3 mg/L. This can vary slightly depending on the laboratory and the specific method used for measurement.
Low Values - Possible Causes
Low values of urinary β2-microglobulin are less common and usually not clinically significant. However, they may be observed in cases of severe protein malnutrition, certain genetic disorders, or after kidney transplantation when there's a successful graft function.
High Values - Possible Causes
High values of urinary β2-microglobulin can indicate conditions such as proximal tubular dysfunction, acute or chronic kidney disease, heavy metal poisoning, interstitial nephritis, or post-renal transplant rejection.
