Container/Tube: 6 plastic, 10-mL urine tubes (Supply T068)
Specimen Volume: 40 mL
1. Collect a random urine specimen and divide the urine into 6 tubes
2. Specimen pH should be between 4.5 and 8 and will stay in this range if kept refrigerated. Specimens with pH >8 indicate bacterial contamination, and testing will be canceled. Do not attempt to adjust pH as it will adversely affect results.
1. Patient's age is required.
2. A timed 24-hour urine collection is the preferred specimen for measuring and interpreting this profile to determine kidney stone risk factors. Random collections with individual analytes normalized to urinary creatinine may be of some clinical use in patients who cannot collect a 24-hour specimen, typically small children. Therefore, this test is offered on random collections for children <16 years old.
Specimen must have a pH between 4.5 and 8 to be acceptable.
