T3 Uptake Method Comparison

A lab needs to do a method comparison between old and new instruments for T3 uptake (T3U) and is wondering how to go about it. One respondent recommended doing an ANOVA to show that there is no difference between the new and old T3U, as well as a regression analysis between T4 X T3U = FTI. However, other respondents suggested retiring the T3U test altogether—many labs consider it obsolete and the American Thyroid Association recommends using TSH along with free thyroxine (FT4) testing to diagnose and manage most patients with thyroid disorders.
