ARUP prints 60-120 ug/dL for all ages and Quest prints 60-130 ug/dL for adults, so the lower limit agrees and the upper limit varies by about 25 ug/dL; use the interval printed on your own report. For comparison, IZiNCG cutoffs used to assess zinc status in populations (not to diagnose one person) for people 10 and older are below 74 ug/dL (men) or 70 ug/dL (women) in a fasting morning sample, below 70 and 66 in a non-fasting morning sample, and below 61 and 59 in an afternoon sample. In a US survey, average serum zinc was about 85 ug/dL in males and 81 ug/dL in females. Results above the interval usually reflect supplements or tube contamination, and long-term excess zinc can lower copper.
