Turnaround Time1 week
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.
