Blood is a transporting and circulation system, providing tissues with minerals, trace elements including toxins. Metals circulate in the blood stream for approximately 72 hours, after which they are naturally excreted or deposited in various body tissues.
Elevated blood metals indicate immediate exposure, reduced concentrations of essential minerals and trace elements reflect an inadequate intake and may be a sign of a nutritional deficiency.
Whole blood levels reflect the intra- and extracellular metal concentration; serum and plasma levels indicate extracellular levels only.
To confirm acute metal toxicity, further diagnostics may be needed such as an appropriate provocation test.
To confirm or rule out longterm exposure, hair analysis is recommended.
