Why This Biomarker Matters

Elevated urinary beta-2 globulin indicates kidney tubule damage. Early detection helps identify kidney disease and guides intervention to slow progression.

Overview

Beta-2 globulin (or beta-2 microglobulin) is a small protein normally filtered by kidneys but reabsorbed in the proximal tubules. Elevated urinary beta-2 globulin indicates kidney tubular damage or dysfunction, as healthy kidneys should not excrete significant amounts. This can reflect early kidney disease, drug toxicity, or metabolic problems. The 24-hour collection quantifies total protein loss, helping assess kidney function severity.
