Thyroid function tests (TFTs) are amongst the most commonly requested laboratory investigations in both primary and secondary care. Fortunately, most TFTs are straightforward to interpret and confirm the clinical impression of euthyroidism, hypothyroidism or hyperthyroidism. This guide aims to recap the hypothalamus-pituitary-thyroid axis and give a structure for you to interpret TFTs, along with explaining a few caveats. Hypothalamic-pituitary-thyroid (HPA) Axis

The results of thyroid function tests (TFTs) must always be interpreted in light of the clinical status of the patient: hypothyroid, euthyroid or hyperthyroid Awareness of the conditions and/or disorders that can be associated with different patterns of TFTs guides further investigation and management

Thyroid function tests are blood tests which help to check the function of your thyroid gland. They are mainly used to detect an underactive thyroid gland (hypothyroidism) and an overactive thyroid gland (hyperthyroidism). Abstract. For general screening of children who are in fairly good health and in whom CNS or pituitary disease is not strongly suspected, the newer THS assays are very useful in assessing the action of both endogenous and exogenous thyroid hormone.

Interpretation of the results of thyroid function tests is facilitated by an understanding of thyroid hormone physiology, especially the normal inverse relationship between free T 4 and TSH concentrations. Variations in assay performance mean that it may be helpful to consistently use the same laboratory for an individual patient.
