General Information
Indications – ?toxicity (particularly PN overload)
Blood measurement is the approach of choice for investigating PN overload, for other situations, blood and urine should be sent, although the usefulness of analysis for occupational monitoring purposes is questionable unless the exposure has been gross. Monitoring for Mn deficiency is not undertaken because the problem has yet to be convincingly demonstrated in humans and it is extremely difficult to collect blood without contaminating it to concentrations within the normal range.
