Also, 10–15% of normal individuals can have high level anti-TPO antibody titres. [ 4 ] [ 6 ] [ 7 ] High serum antibodies are found in active phase chronic autoimmune thyroiditis. Thus, an antibody titer can be used to assess disease activity in patients that have developed such antibodies.
These normal hormonal changes often make pregnancy look like a hyperthyroid state but may be within the normal range for pregnancy, so it necessary to use trimester specific ranges for TSH and free T4. [23] [24] True hyperthyroidism in pregnancy is most often caused by an autoimmune mechanism from Graves' Disease. [23]
One study of patients treated with levothyroxine observed that 35 out of 38 patients (92%) had declines in thyroid peroxidase antibody levels over five years, lowering by 70% on average. 6 of the 38 patients (16%) had thyroid peroxidase antibody levels return to normal. [116]
Between 1990 and 2000, 43 cases were published. Since that time, research has expanded and numerous cases are being reported by scientists around the world, suggesting that this rare condition is likely to have been significantly undiagnosed in the past. Over 100 scientific articles on Hashimoto's encephalopathy were published between 2000 and ...
Thyroid function tests (TFTs) is a collective term for blood tests used to check the function of the thyroid. [1] TFTs may be requested if a patient is thought to suffer from hyperthyroidism (overactive thyroid) or hypothyroidism (underactive thyroid), or to monitor the effectiveness of either thyroid-suppression or hormone replacement therapy.

Reference ranges often depend on the analytical method used, for reasons such as inaccuracy, lack of standardisation, lack of certified reference material and differing antibody reactivity. [11] Also, reference ranges may be inaccurate when the reference groups used to establish the ranges are small. [12]
Thyroid peroxidase is a frequent epitope of autoantibodies in autoimmune thyroid disease, with such antibodies being called anti-thyroid peroxidase antibodies (anti-TPO antibodies). This is most commonly associated with Hashimoto's thyroiditis. Thus, an antibody titer can be used to assess disease activity in patients that have developed such ...
