CS Site-Specific Factor 6
Urinary 5-HIAA Lab Value
Notes
**Note 1**: Carcinoid tumors can release large amounts of serotonin. 5-Hydroxyindoleacetic acid (5-HIAA) is-a breakdown product of the hormone serotonin. The 5-HIAA test measures the amount of acid secreted in the urine over a 24-hour period. **Note 2**: Record to the nearest milligram (mg) the highest 5-HIAA lab value documented in the medical record prior to treatment. For example, code a pretreatment 5-HIAA of 550 mg over 24 hours as 550. **Note 3**: Code 000 is reserved for exactly 0 mg (no measurable amount of 5-HIAA). Do not round tiny values down to 0 ng/ml; any measured value less than or equal to 1 mg should be coded 001. For code 001, also round 1.1-1.4 mg down to 1 ng/ml. For codes 002-979, round values to the nearest mg. **Note 4**: For an uncertain value, record the stated closest value. For example, code a value stated as "less than 5 mg" as 005.Default
