TSH-T4 relationship?

[Guest guest]

Refering to Andys book what does it mean if someones TSH-T4

relationship is to the left and outside of the normal area? My GF has

history of hypothyroid, but all thyroid test normal (other then the

relationship) has indicators of thyroid or copper problem. (low K) and

goiter and nodules on thyroid ultrasound. In addition to this, she

meets counting rules. Also, has low HDL which andy indicates can be

because of mercury. What does this relationship T-4-TSH mean if it is

left of normal?

Thanks!
