Abstract
Traditional balance techniques have given variable data on Zn absorption by the premature infant. However, in the majority of studies undertaken prior to 36 weeks post-conception, Zn absorption has not been sufficiently positive to meet calculated requirements for growth. Use of stable isotopes can help to avert some of the potential sources of error with traditional balance studies and allows measurement of true absorption. This was a pilot study of 70 Zn absorption in premature infants, in which isotopically enriched zinc was fed and Zn stable isotope ratios in fecal samples were measured by a Fast Atom Bombardment/Mass Spectrometry (FAB/MS) technique (1).
