Frequently Asked Questions
What does urine Beta-2 Microglobulin measure?
It measures a small protein filtered by the glomerulus and reabsorbed by the proximal tubules. Elevated levels indicate proximal tubular damage or dysfunction.
Why is this test ordered?
It helps detect early kidney tubular damage from conditions like drug toxicity (aminoglycosides, cisplatin), heavy metal exposure, or chronic kidney disease.
Is fasting required for this test?
No, fasting is not required. A random urine sample is sufficient for Beta-2 Microglobulin estimation.
How is the sample collected?
A 5 mL random urine sample is collected in a clean, dry container. First-morning urine is preferred for better concentration accuracy.
What causes high urine Beta-2 Microglobulin?
Proximal tubular injury from medications, heavy metals, diabetes, hypertension, or inflammatory kidney conditions can impair reabsorption and raise urinary levels.
