Clinical Application
Mercury amalgam fillings - measurement of urinary mercury is not helpful for identifying increased mercury exposure due to dental amalgam. A chelation challenge should not be performed. Blood and urine measurements can be carried out but only after abstinence from fish consumption for one week prior to collection (consider whether low levels may provide reassurance).
