<prompt> Thyroid hormones in blood is transpoed by:AlbuminGlobulinPrealbuminAll  <response>: A i.e. Albumin; B i.e. Globuin; C i.e. Prealbumin Thyroid hormones in blood is transpoed combined with plasma proteins. Normally 99.9 of T4 T3 in plasma is protein bound. Plasma protein which bind T4 T3 are: i AlbuminQ ii Thyroxine binding prealbuminQ TBPA new called transthyretin iii Thyroxine binding globulinQ TBG: affinity to bind T4 is maximum.
