Fractional absorption of zinc [ Time Frame: 33 days ] [ Designated as safety issue: No ]
Fractional absorption of zinc is estimated by using the double isotope tracer ratio technique by administering 67Zn as oral and 70Zn as intravenous stable isotopes.The urinary enrichment with both isotopes is measured in a spot urine sample by inductively coupled plasma mass spectrometry.
