Unusual malabsorption of levothyroxine
Abstract
We report a 50-year-old woman, with overt hypothyroidism undergoing thyrotropin (TSH)-stimulating hormone suppressive levothyroxine (LT4) treatment after subtotal thyroidectomy. At her first visit to our department, the laboratory results revealed a borderline low free thyroxine (FT4) level accompanied by a clearly elevated TSH level. Both parameters did not significantly change during therapy with an oral dose of 500 microg of LT4. Investigations revealed malabsorption of oral administrated LT4. Thyroid serum hormone levels only became normal during parenteral therapy with LT4.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
