Res-O-Mat T3is an in vitro131I-T3diagnostic test used for determining the T3binding capacity of serum. An index of this binding capacity (TBC Index) is obtained by comparing the quantity of T3bound by the patient serum with that bound by pooled normal standard sera.
“Res-O-Mat T3Kit” was used in 108 cases. The test procedure was examined and the following results were obtained.
1) TBC Index: 0.86-1.11 (average 0.972) for 21 normal persons, 0.62-0.9 (average 0.764) for 24 cases with hyperthyroidism, 1.13-1.39 (average 1.215) for 4 cases with hypothyroidism, 0.83-1.13 (average 0.997) for 21 cases of non toxic goiter, and 1.05 and 1.12 for 2 cases of subacute thyroiditis. The test demonstrated that the indices obtained with hyperthyroid, euthyroid, and hypothyroid persons very slightly overlapped.
2) TBC Index decreased as the incubation time increased.
3) TBC Index was influenced by temperature of incubation.
Res-O-Mat T3 Kit doesn't need washing process, needs only 0.5ml of sera, and requires extremely simple procedure.
