For cadmium, a worker's exposure
can be assessed by either blood or urine samples; but the sample
type dictates the information gained about that exposure.
Blood cadmium levels reflect more recent exposures (previous
months) whereas urine levels reflect current lifetime exposure.
If using biological monitoring to
assess the current adequacy of control in the workplace, then blood
cadmium is recommended as it is a better reflection of current body
burden and will respond more quickly to any improvements or
interventions. If a blood sample indicates that excessive
exposure has occurred then a urine sample can be useful in
determining whether this is a short-term issue or has likely been
ongoing for an extended period of time. A urine sample can
also be measured for retinol binding protein to determine if there
are any early health effects as a result of the exposure.
