Background: Morbidity and mortality are associated with thyroid hormone levels in populations. This has invited a debate on what is the better parameter for assessment of thyroid function: the controlling hormone thyrotropin (TSH) or peripheral thyroid hormone measurements (thyroxine (T4) and triiodothyronine (T3)).Aim: To assess the ability of TSH and total T4 (TT4) to discriminate between subtle differences in thyroid function.Me...

Objectives: Measurement of TSH-receptor antibodies (TRAb) in hyperthyroid, pregnant women is an important tool when distinguishing between the autoimmune Graves’ disease and the physiological gestational hyperthyroidism. Evidence to support a cut-off for TRAb in early pregnancy is needed along with information on the frequency and follow-up of TRAb-positive as opposed to TRAb-negative hyperthyroidism.Methods: Within the North Denmark Region Pregnanc...

Objectives: Thyroid disease in women of reproductive age is predominantly of autoimmune origin, and thyroid peroxidase antibodies (TPO-Ab) as well as thyroglobulin antibodies (Tg-Ab) are key markers of autoimmune hypothyroidism. Adding to this, much focus in pregnancy is on euthyroid women who are positive for thyroid autoantibodies. The observational findings are diverse, and evidence to substantiate the applied cut-offs for definition of thyroid autoantibody-positivity in ea...
