Measurement of serum thyroxine-binding capacity.
A new method for free thyroxine-binding sites on thyroxine-binding globulin has been described. This method for thyroxine-binding capacity has the virtues of reasonable specificity and convenience for routine use. When used with serum thyroxine levels it should be valuable in the calculation of free thyroxine and total thyroxine-binding globulin. A more directly estimated TBC as reported here should have more value than the various and more empirical T3 uptake methods.
