Chronological changes in values for thyroid radioiodine uptake measurements (RID) have
been reported in the last four decades. These changes are attributed to geographical and …

Although in vitro measurements of serum thyroid hormones and particularly the sensitive
TSH assay have in recent years taken over as first-line tests, measurement of the thyroid …

A 24-hour thyroid uptake test of sodium iodide I131 performed on 66 euthyroid subjects in
Chicago has been analyzed. The new normal range, based on mean±2 standard deviations …

Thyroidal radioiodine uptake data for 8813 euthyroid subjects (2559 males, 6254 females)
were obtained from 11 American, 5 Australian, and 2 far eastern hospitals. Corrections were …

The authors have developed a method to estimate the 24-hour sodium iodide thyroid uptake
based on a 5-minute Tc-99m pertechnetate thyroid uptake using the equation: Estimated …

RESULTS Results of the radioactive iodine uptake on 432 euthyroid patients are shown in
the histogram of Fig. 1. The mean value is 17.4% with a range of 0.8-63.5%. This figure also …

The radioactive iodine uptake (RAIU) merits a position of prominence in thyroid function
testing. With reasonable care function testing. With reasonable care technical errors virtually …

METHODS Thyroid uptake and biologic half-time measurements were made on 127patients
treated for hyperthyroidism at the Harbor UCLA MedicalCenter. No distinctionwas made …

Equations are given for the conversion of the 24-hr thyroidal uptake of radioiodine (U24) to
its equivalent fractional thyroidal clearance rate (k1). Data on U24 for several different …

Results of tests of thyroid function in Arkansas patients have been analyzed with the aid of a
digital computer. Included in the series were 467 patients unaffected by prior medication …
