Senast uppdaterad: Senast reviderad:


Definition:
Subklinisk hypertyreos definieras som lågt eller inte mätbart TSH med samtidiga normala värden på FT4 och FT3.
Förekomst:
Prevalensen verkar vara <1 %.
Symtom:
Även om tillståndet per definition är utan symtom, kan vaga symtom och tecken på tyreotoxikos förekomma.
Kliniska fynd:
Som regel normala fynd, bedöm eventuell struma och förmaksflimmer.
Diagnostik:
TSH, FT4, FT3 och autoantikroppar för tyroidea.
