UroRisk® Diagnostic Profile

Use only Quest 24-hour Urine Collection Kits specific for renal stone formation diagnosis. Follow instructions in the kit. Test should not be ordered on patients taking lithium, as lithium can affect results. For additional information, please contact the Quest Diagnostics Nichols Institute of Valencia at 800-421-4449.

1.) Upon completion of 24-hour collection in the large orange collection container, tighten the cap on the container and mix contents in the container vigorously for one minute. A good mix will assure accurate test results.
2.) Carefully fill the two plastic white vials with urine collected in the large orange container. The two white vials must be filled within two to four hours of completion of 24-hour collection. Fill and cap vials one at a time. Cap both vials tightly, write patient's name on each vial, and place in zip-lock bags provided (do not remove absorbent sheets).
3.) Complete the patient information section. (Patient's weight is no longer needed.)
4.) Place specimen in mail-back box and mail to the laboratory. DO NOT MAIL LARGE ORANGE COLLECTION CONTAINER.

For High Urine Output: Patient with a high urine output (greater than 3.8 L) will require more than one large container. Collect urine in the first container until it is 3/4 full and then begin filling the second container to complete the 24-hour collection. Carefully follow steps 1-4 for each jug and mark one as box 1 of 2 and the other box 2 of 2.
