No special preparation is required for this test. You may eat, drink, and take your medications as normal, unless instructed otherwise by your healthcare provider.
Patient should empty the bladder, then drink a large glass of water and collect a urine sample within one hour. Significant loss of β2-microglobulin activity may occur in acidic urine (pH ≤6). Urine should always be collected at high diuresis and the pH adjusted to between 6 and 8 with 1 mol/L sodium hydroxide.
