Hypothyroidism is second only to diabetes mellitus as the most common endocrine disorder , In primary hypothyroidism, the thyroid-stimulating hormone (TSH) level is elevated, and free thyroid hormone levels are depressed, in contrast, patients with secondary hypothyroidism have a low or undetectable TSH level , When symptoms are nonspecific, a follow-up assessment of the free thyroxine (T4) level can help distinguish between primary and secondary hypothyroidism 

Laboratory Values in Hypothyroidism *

TSH level
Free T4 level
Free T3 level
Likely diagnosis

High
Low
Low
Primary hypothyroidism

High (>10 µU per mL [10 mU per L])
Normal
Normal
Subclinical hypothyroidism with high risk for future development of overt hypothyroidism

High (6 to 10 µU per mL [6 to 10 mU per L])
Normal
Normal
Subclinical hypothyroidism with low risk for future development of overt hypothyroidism

High
High
Low
Congenital absence of T4-T3­converting enzyme; amiodarone (Cordarone) effect on T4-T3 conversion

High

Peripheral thyroid hormone resistance

Low

Pituitary thyroid deficiency or recent withdrawal of thyroxine after excessive replacement therapy

TSH = thyroid-stimulating hormone; T4 = thyroxine; T3 = triiodothyronine
