Euthyroid sick syndrome must be differentiated from other causes of hypothyroidism on the basis of clinical features and laboratory findings.  
[[Euthyroid]] sick syndrome must be differentiated from other causes of [[hypothyroidism]] on the basis of clinical features and laboratory findings. In [[euthyroid]] sick syndrome, serum [[T3]] is decreased more than [[T4]], the T3RU (T3 resin uptake) is high, and [[Thyroid-stimulating hormone|TSH]] is normal or mildly decreased. In [[primary hypothyroidism]], serum [[T4]] is decreased more than [[T3]], the T3RU (T3 resin uptake) is low, and [[TSH]] is increased. Other causes of [[hypothyroidism]] include transient hypothyroidism, sub-clinical hypothyroidism, central hypothyroidism ([[pituitary]] or [[Hypothalamic|hypothalamic]]) and peripheral [[resistance]] to [[Thyroid-stimulating hormone|TSH]]/[[Thyrotropin-releasing hormone|TRH]].

Overview

Euthyroid sick syndrome must be differentiated from other causes of hypothyroidism on the basis of clinical features and laboratory findings. In euthyroid sick syndrome, serum T3 is decreased more than T4, the T3RU (T3 resin uptake) is high, and TSH is normal or mildly decreased. In primary hypothyroidism, serum T4 is decreased more than T3, the T3RU (T3 resin uptake) is low, and TSH is increased. Other causes of hypothyroidism include transient hypothyroidism, sub-clinical hypothyroidism, central hypothyroidism (pituitary or hypothalamic) and peripheral resistance to TSH/TRH.

Differentiating Euthyroid sick syndrome from other Diseases

Euthyroid sick syndrome must be differentiated from other causes of hypothyroidism on the basis of history and symptoms and laboratory findings:[1][2][3]
