RT Journal Article SR Electronic T1 Euthyroid Range Reevaluation for Radioactive Iodine Uptake Test JF Journal of Nuclear Medicine Technology JO J. Nucl. Med. Technol.

YR 1985 UL http://tech.snmjournals.org/content/13/4/206.abstract AB A new radioactive iodine uptake euthyroid range with 131I was obtained at our institution. The thyroid status of 150 patients seen at this institution for RAIU tests was determined utilizing thyroid hormone levels. A mean and standard deviation (s.d.) of the RAIU was calculated on the 57 patients with normal hormone levels. Two s.ds. about the mean yielded a range of 3.0–37.4%. We established a new normal range of 10–35% with the previous normal range being 10–30%.
