Units for Blood Lead Measurement |
|
|
Units for blood lead can be confusing. Most
clinical laboratories in the UK report results in µmol/l
to be consistent with the reporting of all other clinical
measurements in mol/l units. However, the legislation for
lead exposure is still based on a blood lead measurement
in a now archaic unit, µg/100 ml. The unit of volume for
either mass (e.g. µg) or molar (e.g. µmol) unit
standards is now the litre (l) and logically a system set
to 100 ml as volume should have no place in modern
science. Please note that the units µg/100 ml are also referred to as:
