Total thyroxine binding capacity in Serum or Plasma

Total TBC SerPl

Definition

  • T-uptake in T uptake units. T uptake units bear a rough INVERSE relationship to the other T uptake (See AxSym package insert: http://www.promtest.am/tests/thyroid-diagn/T-Uptake.pdf), but actually measures a different phenomenon (total binding capacity instead of unbound hormone).
