Method Name

Quantitative Chemiluminescent Immunoassay

Reporting Name

Beta-2-Microglobulin, Urine

Specimen Type

Urine


Specimen Required


1. Patient should empty bladder.

2. Have patient drink at least 0.5 liters of water.

3. Within 1 hour, collect a random urine specimen.

4. Transfer 3 mL from a well-mixed random collection to plastic, 10-mL urine tube (T068).
