Trichloroacetic Acid, Urine
Use
Trichloroacetic Acid, Urine is used for assessing exposure to trichloroethylene, tetrachloroethylene, and related compounds. The clinical utility lies in its ability to detect and quantify exposure levels in individuals who are potentially exposed to these chemicals through their occupation or environment. This test aids in occupational medicine by establishing biological exposure indices and evaluating if safe exposure levels are maintained.
Special Instructions
Submit a 10 mL aliquot from a random or spot urine sample collected at the end of shift, end of exposure, or end of workweek. Ensure the specimen is sent refrigerated. Unauthorized users can't access pricing details unless they sign in. New clients must establish a contact with Mayo Clinic Laboratories to optimize test selection and pricing.
Limitations
The test measures Trichloroacetic Acid levels but does not specify the exact source of exposure (e.g., occupational vs. environmental) due to variability in absorption, distribution, metabolism, and excretion. Variations in biological exposure indices can occur based on individual differences. Specific thresholds for toxic exposure are not established for all markers, making the interpretation challenging for unestablished toxic levels. Variability in exposure time, frequency, and metabolic differences can affect measurement results.
