Another study from Brazil [2]
measured urinary iodine excretation and serum TPOAb and TgAb antibodies from 39 subjects with Hashimoto's, none of whom were receiving treatment at the time of the study.
Another study from western Australia (a region that has previously been shown to be iodine replete)
measured urinary iodine concentration (UIC) of 98 women at 6 months postpartum and checked their thyroid status both postpartum and 12 years later [23].
Before introduction of iodized salt and at 10, 20, 40, and 52 weeks, we
measured antithyroid peroxidase antibodies (TPO - Ab), antithyroglobulin antibodies (Tg - Ab),
urinary iodine (UI), and thyroid hormones, and examined the thyroid using ultrasound.
