T3 total vs free t3
WebOct 16, 2013 · Intracellular T3 levels regulate pituitary secretion and blood levels of TSH, as well as the effects of thyroid hormone in multiple organs. However, T3 levels in blood are not reliable indicators of intracellular T3 concentration. Compared to patients with intact thyroid glands, patients taking T4 may have higher blood T4 and lower blood T3 levels. WebData are presented as a median with a 25 to 75 interquartile range of observed values, and categorical variables are described by counts or percentages. The studied groups (T0, T3, and C) were compared by Mann U–Whitney or Kruskal–Wallis ANOVA test and T0 vs. T3 was checked by the Wilcoxon signed-rank test.
