Normal or raised TSH, raised free thyroid hormones
Normal or elevated TSH in the presence of raised free thyroid hormones is a rare disorder but may be clinically important.
The causes of this pattern of abnormality are:
- artefact - need to repeat the tests
- interfering antibodies
- familial dysalbuminaemic hyperthyroxinaemia
- amiodarone therapy
- thyroid hormone receptor mutations
- acute psychiatric disease
- TSH secreting pituitary tumour
- intermittent thyroxine overdosing
