Transcription

1 Reporting Title: Supersaturation, U Performing Location: Rochester Specimen Requirements: Container/Tube: Plastic, 60-mL urine bottle Specimen Volume: 35 ml Collection Instructions: 1. Collect urine for 24 hours. 2. Add 30 ml of toluene as preservative at start of collection, or refrigerate specimen during and after collection. 3. 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 cancelled. Do not attempt to adjust ph as it will adversely affect results. Additional Information: Hour volume is required. 2. Patient's height in centimeters and weight in kilograms are required if patient is <18 years old. 3. See Urine Preservatives in Special Instructions for multiple collections. Forms: If not ordering electronically, submit a General Request Form (Supply T239) with the specimen.
