CATU | Test | CATU | [NAME], [NAME] | Catecholamine Fract, Free, U | High-Performance Liquid Chromatography (HPLC) Includes unconjugated epinephrine, norepinephrine, and dopamine | [NAME], 24-hour graduated: 24Urine |  |  | 2 | mL | Container/Tube: Plastic, 10-mL urine tube (Supply T068) [NAME]: 2 mL Collection Instructions: 1. Collect urine for 24 hours. 2. Add 25 mL of 50% acetic acid as preservative at start of collection. Use 15 mL of 50% acetic acid for children <5 years old. This preservative is intended to achieve a pH of between approximately 2 and 4. 3. This assay is of greatest value when the specimen is collected during a hypertensive episode. 4. Discontinue any epinephrine, norepinephrine, or dopamine injections/infusions at least 12 hours before specimen collection, unless drug monitoring is the goal. 5. Discontinue drugs that release or hinder metabolism of epinephrine, norepinephrine, or dopamine for at least 1 week before obtaining the specimen (see [NAME] for details). If this is not possible for medical reasons, contact the laboratory to discuss whether a shorter drug-withdrawal period may be acceptable. 6. Do not perform the test on patients withdrawing from legal or illegal drugs known to cause rebound plasma catecholamine release during withdrawal (see [NAME] for details). Additional Information: 1. 24-Hour volume is required. 2. See [NAME] in Special Instructions for multiple collections.
