How is the level of metal ions measured?
The measurement is not performed in every laboratory, and is best carried out on ‘whole blood’ not just the plasma. It is also best done in a laboratory that specializes in the test, so that the results are reliable. A technique called ‘mass spectroscopy’ is used. This requires a special and quite expensive instrument, which explains why many labs don’t do the measurement themselves.
