血清亜鉛値80 µg/dL の意味するもの

抄録

When conducting widespread medical examinations throughout our municipality, our team of clinicians discovered many subjects who exhibited symptoms of zinc deficiency despite having serum zinc levels above 65 µg/dL, the commonly accepted limit of zinc deficiency. In this paper, we propose that the range used to express zinc deficiency be adjusted upwards to a new limit of 80µg/dL. When our research team used this higher value in our diagnoses of community members involved in the study, we correctly diagnosed zinc deficiency 91% of the time, with only 9% of our diagnoses being false negatives. Using the new limit, 25% of patients may be falsely diagnosed with a zinc deficiency (false positive) if their complaints or physical signs are not appropriately considered.
