• UroRisk® Panel 15565

  14 analytes · Urine · Fasting not stated · Turnaround Set up: Mon-Sat

  Method and collection

  Method

  Inductively Coupled Plasma-Optical Emission Spectrophotometry • Ion Chromatography • Spectrophotometry (SP) • Calculation

  Collection

  No Reference Range has been established for pediatric patients <14 years old. Use only Quest 24-hour Urine Collection Kits (Mission Pharmacal or GBF, Inc.) 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 SJC at 800-642-4657. 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 ensure accurate test results. 2) Carefully fill the two white plastic 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 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. Note: Urine must only be collected and stored in the large orange collection container. Do not remove sponge from the orange collection container. Do not remove wool from the white container. Do not collect the first urination at the beginning of 24-hour collection. During collection process, store large orange container in a cool location.
