Seriously ill patients often show abnormal TFTs not necessarily associated with thyroid dysfunction, the so-called 'non-thyroidal illness (NTI)' or 'low T3 syndrome' (Demers, 2004).
Non-thyroidal illness (NTI) refers to changes in thyroid hormone levels in critically ill patients in the absence of primary hypothalamic-pituitary-thyroid dysfunction, and these abnormalities usually resolve after clinical recovery.

See related research article The question of whether thyroid hormone supplementation should be provided to critically ill patients without a known history of thyroid disease is not a new debate [ 1].
