Test ID: SSATR
Supersaturation Profile, Pediatric, Random, Urine
Specimen Type 
Describes the specimen type validated for testing
Additional Testing Requirements
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 less than 16 years old.
Necessary Information
Patient's age is required.
Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Supplies:
Urine Tubes, 10 mL (T068)
Aliquot Tubes, 5 mL (T465)
Container/Tube: 2 plastic, 10-mL urine tubes (T068) and 4 plastic, 5-mL urine tubes (T465)
Specimen Volume: 40 mL
Collection Instructions:
1. Collect a random urine specimen and divide the urine into 6 tubes.
2. Refrigerate specimen after collection. Specimen pH should be between 4.5 and 8 and will stay in this range if kept refrigerated. Specimens with pH over 8 indicate bacterial contamination and testing will be canceled. Do not attempt to adjust pH as it will adversely affect results.
Forms
If not ordering electronically, complete, print, and send a Renal Diagnostics Test Request (T830) with the specimen.
Specimen Minimum Volume Defines the amount of sample necessary to provide a clinically relevant result as determined by the Testing Laboratory
Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected
| pH | <4.5 reject >8 reject |
