Beta-2-Microglobulin, Urine
Test Summary
Alternatively, if the collection tubes are not available, the specimen pH must be adjusted to between 6 and 8 using 1N NaOH prior to shipping.
1. Patient should void bladder, then drink at least 500 mL (approximately 17 oz) of water.
2. A urine sample should be collected within 1 hour.
3. Pour exactly 10 mL of random urine into a Quest Diagnostics Beta-2 Microglobulin Transport Tube (available through Client Supply).
4. Ship room temperature.
5. Alternatively, if the collection tubes are not available, the specimen pH must be adjusted to between 6 and 8 using 1N NaOH prior to shipping.
Beta-2 Microglobulin in urine is unstable in acidic urine (less than pH
6). Exactly 10 mL of urine in the Quest Diagnostics Beta-2 Microglobulin Transport Tube is required to achieve the required pH of between 6 and 8. Any volume above or below 10 mL will result in a pH that is outside the acceptable range.
