A method for the determination of the thyroxine-binding index in serum, which method comprises mixing the serum sample to be determined with a defined amount of thyroxine and a defined amount of a determinable enzyme covalently bound to thyroxine, contacting the resulting solution with anti-thyroxine antibodies present in the solid phase, separating the liquid phase from the solid phase, and measuring the activity of said determinable enzyme in one of the phases as a measure of the tyroxine-binding index in said serum sample. |
