A liquid reagent of a stabilized thyroid hormone-immobilized carrier, by which a thyroid hormone can be measured easily in a short time and at low cost, is provided. The liquid reagent of a thyroid hormone-immobilized carrier according to the present invention includes: a thyroid hormone-immobilized carrier; and a solvent, and the pH of the solvent containing the thyroid hormone-immobilized carrier is in the range 8.7 to 11.5. The detection of a thyroid hormone using the liquid reagent of the present invention can be carried out by competitively binding a thyroid hormone in a sample and the thyroid hormone-immobilized carrier in the liquid reagent with an anti-thyroid hormone antibody and detecting a composite of the thyroid hormone-immobilized carrier and the anti-thyroid hormone antibody. According to the present invention, the thyroid hormone-immobilized carrier can be stabilized by setting the pH of the liquid reagent in the predetermined range, so that the liquid reagent can be stored for a long period of time. Moreover, it is not necessary to prepare the thyroid hormone-immobilized carrier every time the measurement is to be carried out, so that the thyroid hormone can be measured easily in a short time and at low cost. |
