ABSTRACT:
The invention relates to a process for the immunological quantitative determination of the T.sub.3 and/or T.sub.4 thyroid hormones.
In a process for the immunological quantitative determination of T.sub.4 thyroxine and/or T.sub.3 triiodothyronine present in free form in a sample, T.sub.3 and/or T.sub.4 to be determined are put into competition with thyroglobulin for the sites of anti-T.sub.3 and/or anti-T.sub.4 antibodies present in a limited quantity, whereafter a determination is made of either the quantity of thyroglobulin fixed to the anti-T.sub.3 and/or anti-T.sub.4 antibodies, or the quantity of thyroglobulin not fixed to the anti-T.sub.3 and/or anti-T.sub.4 antibodies.
Application to the determination of the total T.sub.3 and/or T.sub.4 of a biological sample.
