Don’t Jump the Gun in Diagnosing Subclinical Hypothyroidism
Subclinical hypothyroidism (SCH) is a commonly encountered laboratory finding in clinical practice, characterised by elevated levels of thyroidstimulating hormone (TSH) in serum in the presence of normal serum levels of free thyroxine (FT4), as compared with population-based reference ranges for these values. Overt hypothyroidism, in contrast, is characterised by elevated TSH in combination with subnormal levels of FT4.
