Triiodothyronine uptake rate

3,5,3,-triiodothyronine, also known as anti-rT3, is converted from T4 inner ring deiodination (T4 outer ring deiodination is converted to T3), and almost all rT3 in serum (97) %) is transformed from peripheral tissues by T4. About 50% of the T4 secreted by the thyroid is deiodinated to produce rT3, and about 3% is derived from thyroid secretion. A normal person produces about 32 μg per day and has a serum half-life of 30 to 60 minutes. rT3 is not biologically active, but it is an important controlling effect of thyroid hormone metabolism. Basic Information Specialist Category: Inspection Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Please relax when checking. Normal value 0.23 to 0.35 (23 to 35%). Clinical significance Reduce: hypothyroidism. Elevation: Hyperthyroidism. The result is low , the disease may be high: the result of hyperthyroidism in the elderly is high. Possible diseases: hyperthyroidism, precautions for hyperthyroidism in the elderly In the evaluation of hyperthyroidism, anti-triiodothyronine increased, more sensitive than T3, T4. When treated with antithyroid drugs, T3 decreased faster and rT3 decreased slowly. When both T3 and rT3 are normal, it means that the medication is appropriate. If both rT3 and T4 are lower than the normal value, it means overdose. Inspection process 1. All reagents should be used after being equilibrated to room temperature and loaded strictly according to the operating schedule. 2. Calculate the intake rate. Not suitable for the crowd No taboos. Adverse reactions and risks May cause difficulty breathing.
