Abstract
|
|
|
The serum thyroxine levels were determined by competitive pretein binding analysis using Tetrasorb 1251 Kit in 1.102 cases with various thyroidal states and the reproducibility of T 4 test was studied in 103 cases.
Followings were the results:
1. The mean values of T-4 test were 9.1±2.8 ug/dl in 776 euthyroid cases, 19.41±4.41ug/dl in 297 hyperthyroid cases and 3.6±2.4ug/dl in 29 hypothyroid cases.
2. The diagnostic compatibilities of T-4 test were 90.3% in 776 euthyroid cases, 89.9% in 297 hyperthyroid cases and 84.1% in 29 hypothyroid cases. The diagnostic compatibility of the overall cases was 89.7%.
3. The reproducibility of T-4 test was studied with 103 samplings (103 cases). The difference of -averaged absolute values were 0.84ug/dl in 73 euthyroid cases, 0.47uiug/dl in 27 hyperthyroid cases and 1.1ug/dl in 3 hypothyroid cases. The average difference of absolute value in the overall cases was 0.751ug/dl.
4. It is again conformed that the T-4 test has a higher diagnostic accuracy than those of the conventional methods in various thyroid diseases.
