New York DOH Approval Status
Specimens from New York clients will be sent out to a New York DOH approved laboratory, if possible.
Specimen Required
Patient Preparation
 
Collect
24-hour urine using Calculi Risk/Supersaturation Urine Collection Kit (ARUP supply# 46007). Available online through eSupply using ARUP Connect™ or contact Client Services at (800) 522-2787. Refrigerate during collection.  
Specimen Preparation
Transport four separate 4 mL aliquots from a well-mixed 24-hour urine collection according to the following specifications:
1st aliquot (pH 2): Transfer 4 mL urine into a Sulfamic Acid Tube. (Min: 4 mL) Mix well.
2nd aliquot (pH 2): Transfer 4 mL urine into a Sulfamic Acid Tube. (Min: 4 mL) Mix well.
3rd aliquot (pH 9): Transfer 4 mL urine into a Sodium Carbonate Tube. (Min: 4 mL) Mix well.
4th aliquot: Transfer 4 mL urine into an Unpreserved Tube. (Min: 4 mL)

Freeze specimens immediately after aliquoting. Do not exceed 4 mL in tubes.
If collection kit is unavailable, transport four 4 mL unadjusted aliquots of urine.
Additional information required: Record total volume and collection time on tube and test request form.  
Storage/Transport Temperature
Frozen.  
Unacceptable Conditions
Any specimen other than 24 hour urine collection.  
Remarks
Record total volume on transport tubes and test request form.

Interpretive Data
The values determined for this specimen are placed on the chart to indicate the approximate risk associated with the particular concentrations. Increased risk is to the right of center; decreased risk, to the left. Relative supersaturation calculated for calcium oxalate, calcium hydrogen phosphate (brushite) and uric acid calculi is displayed. Relative risk increases from the middle to the right side of this chart.
