| Reference Interval | The biological exposure index for xylene exposure is total methylhippuric acids at a concentration of 1.5 g/L at the end of shift. |
| Interpretation | All three methylhippuric isomers are measured in this assay and the result reported as total urinary methylhippuric acid. |
| Additional Information | Xylene isomers are often present in petroleum hydrocarbon solvents used in paints, lacquers, cleaning agents adhesives and pesticides and as a starting material for the synthesis of organic chemicals. Laboratory exposure occurs in the preparation of tissue samples for histlogical examination. Methylhippuric acid is a urinary metabolite of xylene and therefore can be measured as an indicator of xylene exposure. |
