title: The estimation of serum thyroxine by competitive binding analysis: a modified method.
abstract: The method of estimating serum thyroxine by competitive binding analysis has been examined stage by stage. The extraction procedures recommended by some authors are shown to extract protein as well as thyroxine, and so produce inaccurate results. A modified method is proposed which increases accuracy and precision.
